In meteorology , a low-pressure area , low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis forces . Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis . In meteorology , atmospheric divergence aloft occurs in two kinds of places:

These plans include the withdrawal of funding to
285-612: A convective low acquires a well-hot circulation in the tropics it is termed a tropical cyclone . Tropical cyclones can form during any month of the year globally but can occur in either the northern or southern hemisphere during December. Atmospheric lift will also generally produce cloud cover through adiabatic cooling once the air temperature drops below the dew point as it rises, the cloudy skies typical of low-pressure areas act to dampen diurnal temperature extremes . Since clouds reflect sunlight , incoming shortwave solar radiation decreases, which causes lower temperatures during

Regional development agencies were public bodies established in all nine regions in 1998 to promote economic development. They had certain delegated functions, including administering European Union regional development funds, and received funding from the central government as well. These were abolished in 2012, with statutory functions returning to local authorities and central government; however, smaller scale local enterprise partnerships were voluntarily established to take on some functions relating to coordinating economic priorities and development.

Meteorologists use the term "cyclone" where circular pressure systems flow in the direction of the Earth's rotation, which normally coincides with areas of low pressure. The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale . Warm-core cyclones such as tropical cyclones, mesocyclones , and polar lows lie within

The hot air over the ocean rises, creating a low-pressure area and a breeze from land to ocean while a large area of drying high pressure is formed over the land, increased by wintertime cooling. Monsoons resemble sea and land breezes , terms usually referring to the localized, diurnal (daily) cycle of circulation near coastlines everywhere, but they are much larger in scale - also stronger and seasonal. Large polar cyclones help determine

Polar lows can be difficult to detect using conventional weather reports and are a hazard to high-latitude operations, such as shipping and offshore platforms . They are vigorous systems that have near-surface winds of at least 17 metres per second (38 mph). Tropical cyclones form due to latent heat driven by significant thunderstorm activity, and are warm-core with well-defined circulations. Certain criteria need to be met for their formation. In most situations, water temperatures of at least 26.5 °C (79.7 °F) are needed down to
7125-414: The pressure difference, or pressure gradient , between a high-pressure system and a low-pressure system, the stronger the wind. Thus, stronger areas of low pressure are associated with stronger winds. The Coriolis force caused by the Earth 's rotation is what gives winds around low-pressure areas (such as in hurricanes , cyclones , and typhoons ) their counter-clockwise (anticlockwise) circulation in
7220-537: The purposes of statistical analysis, simply as Regions. International Territorial Level (ITL) is a geocode standard for referencing the subdivisions of the United Kingdom for statistical purposes, used by the Office for National Statistics (ONS). Between 2003 and 2021, as part of the European Union and European Statistical System , the geocode standard used for the United Kingdom were Nomenclature of Territorial Units for Statistics or NUTS . The NUTS code for
7315-437: The region do. The largest university by student numbers is ARU, and the next biggest is Cambridge. The smallest is Essex. For total income to universities, Cambridge receives around £1 billion—around six times larger than any other university in the region. The University of Bedfordshire receives the least income. Cambridge has the lowest drop-out (discontinuation) rate in the region. Once graduated, over 50% of students stay in
7410-556: The region include University Centre Peterborough , University of Suffolk and Writtle College . . The University of Cambridge receives almost three times as much funding as any other university in the region, due to its huge research grant—the largest in England (and the UK). The next largest, by funding, is UEA in Norwich. The University of Essex and Cranfield University also have moderately large research grants, but no other universities in
7505-663: The region, with 25% going to London and 10% going to the South East. Very few go elsewhere—especially the North of England. During the nineteenth century, several formulations of the laws of football, known as the Cambridge rules , were created by students at the University. One of these codes, dating from 1863, had a significant influence on the creation of the original laws of The Football Association . East of England's top representatives in
7600-640: The region. Cambridge hosts two universities: the University of Cambridge and Anglia Ruskin University . It is also the home of the Open University 's East of England branch. Norwich also hosts two universities: the University of East Anglia and Norwich University of the Arts . There are also other towns and cities in the region which have universities including Bedford and Luton ( University of Bedfordshire ), Colchester ( University of Essex ) and Hatfield ( University of Hertfordshire ). Other higher education centres in
7695-471: The regional local authority leaders' boards created in 2009. Regional ministers were not reappointed by the incoming Coalition Government , and the Government Offices were abolished in 2011. From 2011, combined authorities have been introduced in some city regions , with similar responsibilities to the former regional chambers (and in some cases, replacing a regional local authority leaders' board on
7790-480: The regions also had an associated (central) Government Office with some responsibility for coordinating policy, and, from 2007, a part-time regional minister within the Government. House of Commons regional Select Committees were established in 2009. However, the chambers and select committees were abolished in May 2010, restoring these functions to the main tier of local government, with limited functions transferred to
7885-609: The regions they used tended to be different and ad hoc . The stated purpose was as a way of co-ordinating the various regional offices more effectively: they initially involved the Department of Trade and Industry , Department of Employment , Department of Transport and the Department for the Environment . Following the Labour Party 's victory in the 1997 general election , the government created regional development agencies . Around
7980-418: The regulation of road traffic. Nine "standard regions" were set up in 1946, in which central government bodies, statutory undertakings and regional bodies were expected to cooperate. However, these had declined in importance by the late 1950s. Creation of some form of provinces or regions for England was an intermittent theme of post- Second World War British governments. The Redcliffe-Maud Report proposed
8075-684: The same name takes place in the town at St Peter's Church. Much of the region receives the BBC East and ITV Anglia television services, both based in Norwich (the BBC moving from All Saints' Green to The Forum in 2003, and Anglia remaining at its original base, Angia House.) These services broadcast from the Sandy Heath , Sudbury and Tacolneston transmitter groups. Some areas in close proximity to London, including Luton and south Essex , may receive their service from BBC London and ITV London ; in addition,
8170-399: The smaller mesoscale . Subtropical cyclones are of intermediate size. Cyclogenesis can occur at various scales, from the microscale to the synoptic scale. Larger-scale troughs, also called Rossby waves, are synoptic in scale. Shortwave troughs embedded within the flow around larger scale troughs are smaller in scale, or mesoscale in nature. Both Rossby waves and shortwaves embedded within
8265-690: The south-east of the town, Adder Technology ( KVM switches ) at Bar Hill at the A14 /B1050 junction north of the town, Monsanto , Play.com on the Cambridge Business Centre. The Wellcome Trust Genome Campus has the European Bioinformatics Institute at Hinxton east of Duxford near the M11 spur for the A11. These form the so-called Silicon Fen . Marshall Aerospace is at Cambridge Airport on
8360-561: The standard regions, Economic Planning Councils and Boards were set up, comprising appointed members from local authorities, business, trade unions and universities, and in the early 1970s, these produced a number of regional and sub-regional planning studies. These institutions continued to operate until they were abolished by the incoming Conservative government in 1979. However, by the mid-1980s local authorities in most regions had jointly established standing conferences to consider regional planning issues. Regional initiatives were bolstered by
8455-565: The steering of systems moving through the mid-latitudes, south of the Arctic and north of the Antarctic . The Arctic oscillation provides an index used to gauge the magnitude of this effect in the Northern Hemisphere. Extratropical cyclones tend to form east of climatological trough positions aloft near the east coast of continents, or west side of oceans. A study of extratropical cyclones in
8550-681: The sub-regions have no official status and are little used other than for strategic planning purposes. Low-pressure area Diverging winds aloft, ahead of these troughs, cause atmospheric lift within the troposphere below as air flows upwards away from the surface, which lowers surface pressures as this upward motion partially counteracts the force of gravity packing the air close to the ground. Thermal lows form due to localized heating caused by greater solar incidence over deserts and other land masses. Since localized areas of warm air are less dense than their surroundings, this warmer air rises, which lowers atmospheric pressure near that portion of
8645-657: The term is from 1695. Charles Davenant , in An essay upon ways and means of supplying the war , wrote, "The Eleven Home Counties, which are thought in Land Taxes to pay more than their proportion..." then cited a list including these four. The term does not appear to have been used in taxation since the 18th century. East Anglia is one of the driest parts of the United Kingdom, with average rainfall ranging from 450 to 750 mm (18 to 30 in). The area receives such low rainfall amounts because low pressure systems and weather fronts from
8740-465: The world's rainforests are associated with these climatological low-pressure systems. Tropical cyclones generally need to form more than 555 km (345 mi) or poleward of the 5th parallel north and 5th parallel south , allowing the Coriolis effect to deflect winds blowing towards the low-pressure center and creating a circulation. Worldwide, tropical cyclone activity peaks in late summer, when
8835-692: The year. Thermal lows also occur during the summer over continental areas across the subtropics - such as the Sonoran Desert , the Mexican Plateau , the Sahara , South America , and Southeast Asia. The lows are most commonly located over the Tibetan Plateau and in the lee of the Rocky Mountains. Elongated areas of low pressure form at the monsoon trough or Intertropical Convergence Zone as part of
8930-417: Was 6,398,497. Bedford , Luton , Basildon , Peterborough , Southend-on-Sea , Norwich , Ipswich , Colchester , Chelmsford and Cambridge are the region's most populous settlements. According to Census 2021 , Peterborough is the largest city in the East of England at 215,000. The southern part of the region lies in the London commuter belt . The East of England region has the lowest elevation range in
9025-477: Was established by separate legislation as part of the Greater London Authority . In 2011, Greater London remains administered by the Greater London Authority, which consists of an elected London Assembly and a separately elected Mayor of London . Following the abolition of the Government Offices in 2011, it was announced that the former Government Office Regions (GOR) would henceforth be known, for
