#17328914522611452-506: A higher intensity. Most tropical cyclones that experience rapid intensification are traversing regions of high ocean heat content rather than lower values. High ocean heat content values can help to offset the oceanic cooling caused by the passage of a tropical cyclone, limiting the effect this cooling has on the storm. Faster-moving systems are able to intensify to higher intensities with lower ocean heat content values. Slower-moving systems require higher values of ocean heat content to achieve

This replenishing of moisture-bearing air after rain may cause multi-hour or multi-day extremely heavy rain up to 40 km (25 mi) from the coastline, far beyond the amount of water that the local atmosphere holds at any one time. This in turn can lead to river flooding , overland flooding, and a general overwhelming of local water control structures across a large area. A tropical cyclone
1936-493: A number of techniques considered to try to artificially modify tropical cyclones. These techniques have included using nuclear weapons , cooling the ocean with icebergs, blowing the storm away from land with giant fans, and seeding selected storms with dry ice or silver iodide . These techniques, however, fail to appreciate the duration, intensity, power or size of tropical cyclones. A variety of methods or techniques, including surface, satellite, and aerial, are used to assess
2057-422: A process known as rapid intensification, a period in which the maximum sustained winds of a tropical cyclone increase by 30 kn (56 km/h; 35 mph) or more within 24 hours. Similarly, rapid deepening in tropical cyclones is defined as a minimum sea surface pressure decrease of 1.75 hPa (0.052 inHg) per hour or 42 hPa (1.2 inHg) within a 24-hour period; explosive deepening occurs when
2178-429: A remnant low-pressure area . Remnant systems may persist for several days before losing their identity. This dissipation mechanism is most common in the eastern North Pacific. Weakening or dissipation can also occur if a storm experiences vertical wind shear which causes the convection and heat engine to move away from the center. This normally ceases the development of a tropical cyclone. In addition, its interaction with

After being struck by his ski, he was transported to a local hospital before dying from his injuries hours later. As a result of his death, the water events of the Australian Surf Life Saving championships at Kurrawa Beach on the Gold Coast were cancelled. The system made landfall near Airlie Beach, north of Mackay, at about 1:30 am AEST on Sunday morning, 21 March and headed in
3025-518: A tropical cyclone are a result of the conservation of angular momentum imparted by the Earth's rotation as air flows inwards toward the axis of rotation. As a result, cyclones rarely form within 5° of the equator . Tropical cyclones are very rare in the South Atlantic (although occasional examples do occur ) due to consistently strong wind shear and a weak Intertropical Convergence Zone . In contrast,
3146-461: A tropical cyclone's core has a negative effect on its development and intensity by diminishing atmospheric convection and introducing asymmetries in the storm's structure. Symmetric, strong outflow leads to a faster rate of intensification than observed in other systems by mitigating local wind shear. Weakening outflow is associated with the weakening of rainbands within a tropical cyclone. Tropical cyclones may still intensify, even rapidly, in

8470-469: The dominant transport routes; connecting with the Queensland provincial cities of Cairns and Townsville . Cardwell railway station in Bowen Street serves the town ( 18°16′04″S 146°01′42″E / 18.2679°S 146.0282°E / -18.2679; 146.0282 ( Cardwell railway station ) ). The town is a long narrow strip hugging the coast with Greenwood Hill immediately to
8591-486: The equator, then move poleward past the ridge axis before recurving into the main belt of the Westerlies . When the subtropical ridge position shifts due to El Niño, so will the preferred tropical cyclone tracks. Areas west of Japan and Korea tend to experience much fewer September–November tropical cyclone impacts during El Niño and neutral years. During La Niña years, the formation of tropical cyclones, along with
8712-471: The establishment of Port Hinchinbrook, the Marina Public Boat Ramp provides year-round access to the protected marine environments of Hinchinbrook Channel, Estuaries, Islands and Great Barrier Reef. The Cardwell Jetty is an important infrastructure asset, where visitors can socialize and view the coastal scenery; and anglers can enjoy both day and evening fishing activities. The Aboriginal heritage
8833-469: The evaporation of water from the ocean surface, which ultimately condenses into clouds and rain when moist air rises and cools to saturation . This energy source differs from that of mid-latitude cyclonic storms , such as nor'easters and European windstorms , which are powered primarily by horizontal temperature contrasts . Tropical cyclones are typically between 100 and 2,000 km (62 and 1,243 mi) in diameter. The strong rotating winds of
8954-481: The eyewall of the storm, and an upper-level anticyclone helps channel this air away from the cyclone efficiently. However, some cyclones such as Hurricane Epsilon have rapidly intensified despite relatively unfavorable conditions. There are a number of ways a tropical cyclone can weaken, dissipate, or lose its tropical characteristics. These include making landfall, moving over cooler water, encountering dry air, or interacting with other weather systems; however, once
9075-568: The fake post, the then Cassowary Coast mayor Bill Shannon said that he had received phone calls from Muslim leaders from as far away as Sydney encouraging Cardwell to continue with their Christmas light displays. In the 2016 census , the locality of Cardwell had a population of 1,309 people. Aboriginal and Torres Strait Islander people made up 8.9% of the population. 72.5% of people were born in Australia and 83.0% of people spoke only English at home. The most common responses for religion were No Religion 25.6%, Catholic 22.6% and Anglican 20.6%. In
9196-410: The form of cold water from falling raindrops (this is because the atmosphere is cooler at higher altitudes). Cloud cover may also play a role in cooling the ocean, by shielding the ocean surface from direct sunlight before and slightly after the storm passage. All these effects can combine to produce a dramatic drop in sea surface temperature over a large area in just a few days. Conversely, the mixing of
9317-453: The frequency of very intense storms and a poleward extension of where the cyclones reach maximum intensity are among the possible consequences of human-induced climate change. Tropical cyclones use warm, moist air as their fuel. As climate change is warming ocean temperatures , there is potentially more of this fuel available. Between 1979 and 2017, there was a global increase in the proportion of tropical cyclones of Category 3 and higher on
9438-532: The general public regarding forecasts, watches, and warnings. Since the systems can last a week or longer, and more than one can be occurring in the same basin at the same time, the names are thought to reduce the confusion about what storm is being described. Names are assigned in order from predetermined lists with one, three, or ten-minute sustained wind speeds of more than 65 km/h (40 mph) depending on which basin it originates. Standards vary from basin to basin. Some tropical depressions are named in
9559-454: The hands of our countrymen, who employ native troopers, commanded by white men to hunt down and destroy the offenders when the opportunity offers". In January 1872, two British dugong fishermen named Henry Smith and Charles Clements were killed at nearby Goold Island by resident Aboriginals. Wet weather prevented an immediate punitive expedition of four boats of armed local white men who were eager that "the blacks" be "taught that what they do
9680-451: The intensity from leveling off before an eye emerges in infrared imagery. The SATCON weights estimates from various satellite-based systems and microwave sounders , accounting for the strengths and flaws in each individual estimate, to produce a consensus estimate of a tropical cyclone's intensity which can be more reliable than the Dvorak technique at times. Multiple intensity metrics are used, including accumulated cyclone energy (ACE),
9801-522: The intensity of a tropical cyclone. Reconnaissance aircraft fly around and through tropical cyclones, outfitted with specialized instruments, to collect information that can be used to ascertain the winds and pressure of a system. Tropical cyclones possess winds of different speeds at different heights. Winds recorded at flight level can be converted to find the wind speeds at the surface. Surface observations, such as ship reports, land stations, mesonets , coastal stations, and buoys, can provide information on
9922-452: The land and would shoot any who approached, that we were strong and that another party would soon follow", and he also described how a group of Aboriginals "were set upon suddenly by Dalrymple's men and rather cut up." Cardwell Post Office opened on 10 July 1864. In March 1865, Lieutenant Blakeney and seven troopers of the Native Police spent two days clearing the area around Cardwell of Aboriginal presence by "burning camps and dispersing
10043-674: The late 1800s and early 1900s and gradually superseded the existing system—simply naming cyclones based on what they hit. The system currently used provides positive identification of severe weather systems in a brief form, that is readily understood and recognized by the public. The credit for the first usage of personal names for weather systems is generally given to the Queensland Government Meteorologist Clement Wragge who named systems between 1887 and 1907. This system of naming weather systems fell into disuse for several years after Wragge retired, until it
10164-402: The local people through his interpreter that he had come to take possession of their lands, Dalrymple bizarrely expressed frustration at the supposed inability of the aboriginals to understand the concept of "Thou shalt not steal". James Morrill was more factual in his account of the founding of Cardwell writing that "I then said to [the natives] that they must clear out ... as we wished to occupy
10285-404: The main belt of the Westerlies , by means of merging with a nearby frontal zone, can cause tropical cyclones to evolve into extratropical cyclones . This transition can take 1–3 days. Should a tropical cyclone make landfall or pass over an island, its circulation could start to break down, especially if it encounters mountainous terrain. When a system makes landfall on a large landmass, it
10406-489: The marina. In 2013, the Cardwell community began being the target of an online hoax, which claimed the town's Christmas lights competition had been cancelled to appease the local Muslim community, forcing Cassowary Coast Regional Council to publicly debunk the rumours. Despite this, the hoax continues to circulate on social media. The hoax originated from an Islamophobic post on the "Meanwhile in Australia" Facebook page, which subsequently went viral. The post detailing
10527-575: The natives." In the late 1860s and early 1870s, Cardwell became a transport hub for prospectors heading to the Etheridge Shire goldfields 200 kilometres (120 mi) inland from the town. Captain John Moresby visited Cardwell in 1871 and wrote that "various tribes of aborigines roam about the vicinity, and not unnaturally regard the white men, who are rapidly dispossessing them of their homes, as mortal enemies. They ... suffer terrible retaliation at
10648-522: The observed trend of rapid intensification of tropical cyclones in the Atlantic basin. Rapidly intensifying cyclones are hard to forecast and therefore pose additional risk to coastal communities. Warmer air can hold more water vapor: the theoretical maximum water vapor content is given by the Clausius–Clapeyron relation , which yields ≈7% increase in water vapor in the atmosphere per 1 °C (1.8 °F) warming. All models that were assessed in
10769-466: The overall frequency of tropical cyclones worldwide, with increased frequency in the North Atlantic and central Pacific, and significant decreases in the southern Indian Ocean and western North Pacific. There has been a poleward expansion of the latitude at which the maximum intensity of tropical cyclones occurs, which may be associated with climate change. In the North Pacific, there may also have been an eastward expansion. Between 1949 and 2016, there
10890-402: The possibility of the storm making landfall in the region. Large swells produced by the system prompted lifeguards to close large areas of public beaches. People who wanted to go into the ocean were strongly urged to only do so in patrolled areas. Additionally, fishermen removed their shark nets from the region in anticipation of winds exceeding 65 km/h (40 mph). The removal of shark nets
11011-440: The potential of spawning tornadoes . Climate change affects tropical cyclones in several ways. Scientists found that climate change can exacerbate the impact of tropical cyclones by increasing their duration, occurrence, and intensity due to the warming of ocean waters and intensification of the water cycle . Tropical cyclones draw in air from a large area and concentrate the water content of that air into precipitation over
11132-413: The presence of moderate or strong wind shear depending on the evolution and structure of the storm's convection. The size of tropical cyclones plays a role in how quickly they intensify. Smaller tropical cyclones are more prone to rapid intensification than larger ones. The Fujiwhara effect , which involves interaction between two tropical cyclones, can weaken and ultimately result in the dissipation of
11253-444: The release of latent heat from the saturated soil. Orographic lift can cause a significant increase in the intensity of the convection of a tropical cyclone when its eye moves over a mountain, breaking the capped boundary layer that had been restraining it. Jet streams can both enhance and inhibit tropical cyclone intensity by influencing the storm's outflow as well as vertical wind shear. On occasion, tropical cyclones may undergo
11374-453: The roles of the regulatory processes of the three levels of government in the approval for the development and what might be learned from the experience and how processes might be improved. The Cardwell Library opened in 2008. Cardwell suffered significant damage from Cyclone Yasi , a category 5 cyclone, in February 2011. The marina and the boats within it were destroyed. As at 2019, ongoing legal disputes have prevented work on rebuilding
11495-493: The rough track to Valley of Lagoons, so it was erected in Cardwell instead. Cardwell State School is a government primary (Prep–6) school for boys and girls at 43 Victoria Street ( 18°16′07″S 146°01′51″E / 18.2687°S 146.0308°E / -18.2687; 146.0308 ( Cardwell State School ) ). In 2017, the school had an enrolment of 108 students with 6 teachers (5 full-time equivalent) and 6 non-teaching staff (5 full-time equivalent). In 2018,
11616-492: The same intensity. The passage of a tropical cyclone over the ocean causes the upper layers of the ocean to cool substantially, a process known as upwelling , which can negatively influence subsequent cyclone development. This cooling is primarily caused by wind-driven mixing of cold water from deeper in the ocean with the warm surface waters. This effect results in a negative feedback process that can inhibit further development or lead to weakening. Additional cooling may come in
11737-488: The same system. The ASCAT is a scatterometer used by the MetOp satellites to map the wind field vectors of tropical cyclones. The SMAP uses an L-band radiometer channel to determine the wind speeds of tropical cyclones at the ocean surface, and has been shown to be reliable at higher intensities and under heavy rainfall conditions, unlike scatterometer-based and other radiometer-based instruments. The Dvorak technique plays
11858-554: The school had an enrolment of 80 students with 5 teachers (4 full-time equivalent) and 6 non-teaching staff (5 full-time equivalent). There is no secondary school in Cardwell. The nearest government secondary school is Tully State High School in Tully to the north. Cardwell Police Station is at 49 Victoria Street ( 18°16′04″S 146°01′48″E / 18.2679°S 146.0299°E / -18.2679; 146.0299 ( Cardwell Police Station ) ). Cardwell Fire Station
11979-513: The sea can result in heat being inserted in deeper waters, with potential effects on global climate . Vertical wind shear decreases tropical cyclone predicability, with storms exhibiting wide range of responses in the presence of shear. Wind shear often negatively affects tropical cyclone intensification by displacing moisture and heat from a system's center. Low levels of vertical wind shear are most optimal for strengthening, while stronger wind shear induces weakening. Dry air entraining into
12100-402: The storm washed away several homes along coastal areas. Flooding was also reported on several islands; however, officials confirmed that no fatalities resulted from the storm. Maximum winds on the affected islands reached 120 km/h (75 mph). On Rennell Island, initial reports stated that at least ten homes had been severely damaged or destroyed in several villages. Light to moderate damage
12221-594: The subtropical ridge position, shifts westward across the western Pacific Ocean, which increases the landfall threat to China and much greater intensity in the Philippines . The Atlantic Ocean experiences depressed activity due to increased vertical wind shear across the region during El Niño years. Tropical cyclones are further influenced by the Atlantic Meridional Mode , the Quasi-biennial oscillation and
12342-419: The surface pressure decreases by 2.5 hPa (0.074 inHg) per hour for at least 12 hours or 5 hPa (0.15 inHg) per hour for at least 6 hours. For rapid intensification to occur, several conditions must be in place. Water temperatures must be extremely high, near or above 30 °C (86 °F), and water of this temperature must be sufficiently deep such that waves do not upwell cooler waters to
12463-483: The surface. On the other hand, Tropical Cyclone Heat Potential is one of such non-conventional subsurface oceanographic parameters influencing the cyclone intensity. Wind shear must be low. When wind shear is high, the convection and circulation in the cyclone will be disrupted. Usually, an anticyclone in the upper layers of the troposphere above the storm must be present as well—for extremely low surface pressures to develop, air must be rising very rapidly in
12584-438: The swells continued to increase, they may have to relocate the event elsewhere. These swells were anticipated to be the largest experienced along the Queensland coastline in the past decade and emergency management officials warned residents living along coastal areas that the waves would likely inundate low-lying regions. On 18 March, new forecasts of the future track of Ului indicated that it would make landfall in Queensland. As
12705-621: The system and its intensity. For example, within the Northern Atlantic and Eastern Pacific basins, a tropical cyclone with wind speeds of over 65 kn (120 km/h; 75 mph) is called a hurricane , while it is called a typhoon or a severe cyclonic storm within the Western Pacific or North Indian oceans. When a hurricane passes west across the International Dateline in the Northern Hemisphere, it becomes known as
12826-400: The system. By this time, deep convection had developed around a low-level circulation and banding features had formed. A slow westward movement was expected as the depression was situated north of a subtropical ridge . On 12 March, 13F was upgraded to Tropical Cyclone Ului. By early on 13 March, it was a category 2 cyclone. Later that day, Ului strengthened into a category 3, making it
12947-423: The tropical cyclone year begins on July 1 and runs all year-round encompassing the tropical cyclone seasons, which run from November 1 until the end of April, with peaks in mid-February to early March. Of various modes of variability in the climate system, El Niño–Southern Oscillation has the largest effect on tropical cyclone activity. Most tropical cyclones form on the side of the subtropical ridge closer to
13068-451: The weaker of two tropical cyclones by reducing the organization of the system's convection and imparting horizontal wind shear. Tropical cyclones typically weaken while situated over a landmass because conditions are often unfavorable as a result of the lack of oceanic forcing. The Brown ocean effect can allow a tropical cyclone to maintain or increase its intensity following landfall , in cases where there has been copious rainfall, through
13189-462: The west of the town ( 18°15′50″S 146°00′55″E / 18.2638°S 146.0153°E / -18.2638; 146.0153 ( Greenwood Hill ) ) rising to 64 metres (210 ft) above sea level. West of Cardwell the rugged topography of the Cardwell Range intercepts the trade winds resulting in high rainfall. The coastal escarpment is covered in rainforest which transitions to
13310-654: The west to eucalypt woodland and tropical savanna . Cardwell Range biodiversity has been protected by the introduction of Forestry Reserves, National Parks and Queensland World Heritage Wet Tropics Areas. Seaward lies the Hinchinbrook Channel ( 18°16′26″S 146°03′47″E / 18.2738°S 146.0631°E / -18.2738; 146.0631 ( Hinchinbrook Channel ) ) and Rockingham Bay ( 18°14′18″S 146°03′37″E / 18.2384°S 146.0604°E / -18.2384; 146.0604 ( Rockingham Bay ) ) which are both are part of
13431-402: The wind speed of Hurricane Helene by 11%, it increased the destruction from it by more than twice. According to World Weather Attribution the influence of climate change on the rainfall of some latest hurricanes can be described as follows: Tropical cyclone intensity is based on wind speeds and pressure. Relationships between winds and pressure are often used in determining the intensity of
13552-779: Was 185 kn (95 m/s; 345 km/h; 215 mph) in Hurricane Patricia in 2015—the most intense cyclone ever recorded in the Western Hemisphere . Warm sea surface temperatures are required for tropical cyclones to form and strengthen. The commonly-accepted minimum temperature range for this to occur is 26–27 °C (79–81 °F), however, multiple studies have proposed a lower minimum of 25.5 °C (77.9 °F). Higher sea surface temperatures result in faster intensification rates and sometimes even rapid intensification . High ocean heat content , also known as Tropical Cyclone Heat Potential , allows storms to achieve
13673-485: Was a first in preparation for cyclones. Although the removal of the nets would prevent damage to them from the storm, it left swimmers at risk for shark attacks. A large surfing competition, the Australian Surf Life Saving Championships, welcomed the large swells from the storm, estimated at 5 m (16 ft). Roughly 8,100 people signed up for the competition; however, managers stated that if
13794-523: Was a slowdown in tropical cyclone translation speeds. It is unclear still to what extent this can be attributed to climate change: climate models do not all show this feature. A 2021 study review article concluded that the geographic range of tropical cyclones will probably expand poleward in response to climate warming of the Hadley circulation . When hurricane winds speed rise by 5%, its destructive power rise by about 50%. Therfore, as climate change increased
13915-492: Was described as "via Cardwell". In 1985, it was proposed to build an integrated marina and resort called Port Hinchinbrook at Oyster Point south of the town. The proposal encountered many environmental objections and financial collapse of one of the development companies, before construction commenced in 1999. The long-running controversy led to the Australian Senate establishing an inquiry in May 1998 to try to understand
14036-491: Was downgraded below cyclone strength. 60,000 homes were without power in Cannonvale, Mackay, Proserpine, Sarina and surrounding areas. Most of the major damage occurred at Proserpine and the areas to the south and west such as Crystalbrook, Kelsey Creek, Silver Creek, Dittmer, Gunyarra, Andromache, Bloomsbury, Thoopara etc. Airlie Beach/Cannonvale/Cannonvalley sustained relatively minor damage due to them being sheltered from most of
14157-620: Was first identified by the Fiji Meteorological Service (FMS) late on 9 March 2010 roughly 130 kilometres (81 mi) north of Hiw Island, Vanuatu. At that time, the system was classified as Tropical Disturbance 13F. Early the following day, the system became sufficiently organised for the FMS to upgrade the disturbance to a tropical depression. Several hours later, the Joint Typhoon Warning Center (JTWC) also began monitoring
14278-424: Was led by George Elphinstone Dalrymple . They were 20 in number including James Morrill, William Alcock Tully , botanist John Dallachy , Arthur Jervoise Scott, Lieut. Marlow of the Native Police and his troopers Norman, Archy and Warbragen. Dalrymple also brought his "black boy" servant, an Aboriginal man from Stradbroke Island that he called "Cockey". They came from Bowen on the small schooner Policeman which
14399-522: Was revived in the latter part of World War II for the Western Pacific. Formal naming schemes have subsequently been introduced for the North and South Atlantic, Eastern, Central, Western and Southern Pacific basins as well as the Australian region and Indian Ocean. At present, tropical cyclones are officially named by one of twelve meteorological services and retain their names throughout their lifetimes to provide ease of communication between forecasters and
14520-614: Was sustained on Makira and Guadalcanal, with at least two homes sustaining damage. Unconfirmed reports of a large wave inundating several villages, washing away homes and overturning large boulders came from east Makira around 4:00 pm local time. Another village on the western side of Makira was reportedly inundated roughly five hours later. Later damage assessments made on Makira Island confirmed at least 13 homes were destroyed and several more were damaged. The most severe damage took place in Woau village where ten homes were destroyed. On 19 March,
14641-563: Was under the command of ex- Native Police officer Captain Walter Powell , with the 3 ton cutter Heather Bell in tow. Dalrymple's main purpose in establishing a settlement in Rockingham Bay was to create a port as close as possible to the Valley of Lagoons Station of which he was part owner. Very soon after disembarking from the Policeman , he endeavoured to create a road from the coast to
