Singularity (climate)
A singularity is a weather phenomenon likely to occur with reasonable regularity around a specific approximate calendar date, Barry R.G. & Chorley R.J. (1987), ''Atmosphere, Weather & Climate'', 5th ed, Routledge, outside of more general seasonal weather patterns (e.g., that May Day is usually warmer than New Year's Day in northern locales). The existence of singularities is disputed, some considering them due to seeing patterns in noise and statistical artifacts from small samples. In North America, the most significant purported singularities are January thaw (warmer weather around January 25) and Indian summer (warmer weather in mid-autumn). More fanciful ones include the British tradition that rain on St. Swithun's Day (15 July) will be followed by forty days and nights of rain, and similar folk beliefs around groundhog day. Studies Although folk tales such as St Swithun's Day generally have little credibility, some of these events have a more solid basis. Early scientific ...

Roger G
Roger is a given name, usually masculine, and a surname. The given name is derived from the Old French personal names ' and '. These names are of Germanic origin, derived from the elements ', ''χrōþi'' ("fame", "renown", "honour") and ', ' ("spear", "lance") (Hrōþigēraz). The name was introduced into England by the Normans. In Normandy, the Frankish name had been reinforced by the Old Norse cognate '. The name introduced into England replaced the Old English cognate '. ''Roger'' became a very common given name during the Middle Ages. A variant form of the given name ''Roger'' that is closer to the name's origin is ''Rodger''. Slang and other uses Roger is also a short version of the term "Jolly Roger", which refers to a black flag with a white skull and crossbones, formerly used by sea pirates since as early as 1723. From up to , Roger was slang for the word "penis". In ''Under Milk Wood'', Dylan Thomas writes "jolly, rodgered" suggesting both the sexual double entend ...

Richard Chorley
Richard John Chorley (4 September 1927 – 12 May 2002) was an English geographer, and Professor of Geography at Cambridge University, known as leading figure in quantitative geography in the late 20th century, who played an instrumental role in bringing in the use of systems theory to geography. Biography Early education Chorley was born in Minehead, Somerset in an area known as the West Country, with roots in Exmoor and the Vale of Taunton Deane. He was a product of a local primary school and Minehead Grammar School. Later on, Chorley began studying Geomorphology as an undergraduate at the School of Geography at Oxford. He served with the Royal Engineers from 1946 to 1948 and made it Lieutenant. Afterwards he went up to Exeter College, where he obtained his BA with Honours in 1951. Later in 1954 he also obtained his MA at Oxford University, and in 1974 his Sc.D. at Cambridge University. At Oxford he was greatly influenced by R.P. Beckinsale, who advised Chorley to go on ...

May Day
May Day is a European festival of ancient origins marking the beginning of summer, usually celebrated on 1 May, around halfway between the spring equinox and summer solstice. Festivities may also be held the night before, known as May Eve. Traditions often include gathering wildflowers and green branches, weaving floral garlands, crowning a May Queen (sometimes with a male companion), and setting up a Maypole, May Tree or May Bush, around which people dance. Bonfires are also part of the festival in some regions. Regional varieties and related traditions include Walpurgis Night in central and northern Europe, the Gaelic festival Beltane, the Welsh festival Calan Mai, and May devotions to the Blessed Virgin Mary. It has also been associated with the ancient Roman festival Floralia. In 1889, 1 May was chosen as the date for International Workers' Day by the Second International, to commemorate the Haymarket affair in Chicago and the struggle for an eight-hour working day. ...

New Year's Day
New Year's Day is a festival observed in most of the world on 1 January, the first day of the year in the modern Gregorian calendar. 1 January is also New Year's Day on the Julian calendar, but this is not the same day as the Gregorian one. Whilst most solar calendars (like the Gregorian and Julian) begin the year regularly at or near the northern winter solstice, cultures that observe a lunisolar or lunar calendar celebrate their New Year (such as the Chinese New Year and the Islamic New Year) at less fixed points relative to the solar year. In pre-Christian Rome under the Julian calendar, the day was dedicated to Janus, god of gateways and beginnings, for whom January is also named. From Roman times until the middle of the 18th century, the new year was celebrated at various stages and in various parts of Christian Europe on 25 December, on 1 March, on 25 March and on the movable feast of Easter. In the present day, with most countries now using the Gregorian calendar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation. Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis e ...

January Thaw
January is the first month of the year in the Julian and Gregorian calendars and is also the first of seven months to have a length of 31 days. The first day of the month is known as New Year's Day. It is, on average, the coldest month of the year within most of the Northern Hemisphere (where it is the second month of winter) and the warmest month of the year within most of the Southern Hemisphere (where it is the second month of summer). In the Southern hemisphere, January is the seasonal equivalent of July in the Northern hemisphere and vice versa. Ancient Roman observances during this month include Cervula and Juvenalia, celebrated January 1, as well as one of three Agonalia, celebrated January 9, and Carmentalia, celebrated January 11. These dates do not correspond to the modern Gregorian calendar. History January (in Latin, ''Ianuarius'') is named after Janus, the god of beginnings and transitions in Roman mythology. Traditionally, the original Roman calendar consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Summer
An Indian summer is a period of unseasonably warm, dry weather that sometimes occurs in autumn in temperate regions of the northern hemisphere. Several sources describe a true Indian summer as not occurring until after the first frost, or more specifically the first "killing" frost. Etymology The late 19th-century lexicographer Albert Matthews made an exhaustive search of early American literature in an attempt to discover who coined the expression. The earliest reference he found dated to 1851. He also found the phrase in a letter written in England in 1778, but discounted that as a coincidental use of the phrase. Later research showed that the earliest known reference to Indian summer in its current sense occurs in an essay written in the United States circa 1778 by J. Hector St. John de Crevecoeur. The letter was first published in French. The essay remained unavailable in the United States until the 1920s. Although the exact origins of the term are uncertain, it was perhaps ...

Swithun
Swithun (or Swithin; ang, Swīþhūn; la, Swithunus; died 863 AD) was an Anglo-Saxon bishop of Winchester and subsequently patron saint of Winchester Cathedral. His historical importance as bishop is overshadowed by his reputation for posthumous miracle-working. According to tradition, if it rains on Saint Swithun's bridge (Winchester) on his feast day (15 July) it will continue for forty days. Biography St. Swithun was Bishop of Winchester from his consecration on 30 October 852 until his death on 2 July 863. However, he is scarcely mentioned in any document of his own time. His death is entered in the Canterbury manuscript of the '' Anglo-Saxon Chronicle'' (MS F) under the year 861. He is recorded as a witness to nine charters, the earliest of which (S 308) is dated 854. More than a hundred years later, when Dunstan and Æthelwold of Winchester were inaugurating their church reform, Swithun was adopted as patron of the restored church at Winchester, formerly dedicate ...

Groundhog Day
Groundhog Day ( pdc, Grund'sau dåk, , , ; Nova Scotia: Daks Day) is a popular North American tradition observed in the United States and Canada on February 2. It derives from the Pennsylvania Dutch superstition that if a groundhog emerges from its burrow on this day and sees its shadow due to clear weather, it will retreat to its den, and winter will go on for six more weeks; if it does not see its shadow because of cloudiness, spring will arrive early. While the tradition remains popular in the 21st century, studies have found no consistent association between a groundhog seeing its shadow and the subsequent arrival time of spring-like weather. The weather lore was brought from German-speaking areas where the badger (german: link=no, Dachs) is the forecasting animal. This appears to be an enhanced version of the lore that clear weather on the Christian festival of Candlemas forebodes a prolonged winter. The Groundhog Day ceremony held at Punxsutawney in western Pennsylvani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubert Lamb
Hubert Horace Lamb (22 September 1913 in Bedford – 28 June 1997 in Holt, Norfolk, Holt, Norfolk) was an English climatologist who founded the Climatic Research Unit in 1972 in the School of Environmental Sciences at the University of East Anglia. Career Most of Lamb's scientific life was spent at the Met Office, Meteorological Office, UK, where he started as a Technical Officer progressing by special merit promotion. As a Quaker and conscientious objector, Lamb refused to work on the meteorology of gas spraying during World War II, and was transferred to the Irish Meteorological Service, then still closely associated with the UK Met Office. On returning to the UK service after the war his responsibilities were in the fields of long range weather forecasting, world climatology and climate change. In this capacity he was assigned to West Germany and Malta. Earlier he was also posted as meteorological adviser on a Norwegian whaling factory ship to Antarctica. He became a Membe ...

Climatic Research Unit
The Climatic Research Unit (CRU) is a component of the University of East Anglia and is one of the leading institutions concerned with the study of natural and anthropogenic climate change. With a staff of some thirty research scientists and students, the CRU has contributed to the development of a number of the data sets widely used in climate research, including one of the global temperature records used to monitor the state of the climate system, as well as statistical software packages and climate models. History The CRU was founded in 1972 as part of the university's School of Environmental sciences. The establishment of the Unit owed much to the support of Sir Graham Sutton, a former Director-General of the Meteorological Office, Lord Solly Zuckerman, an adviser to the University, and Professors Keith Clayton and Brian Funnel, Deans of the School of Environmental Sciences in 1971 and 1972. Initial sponsors included British Petroleum, the Nuffield Foundation and Royal D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
