London Tornado Of 1091
The London Tornado of 1091 is the earliest reported tornado in England, occurring in London on Friday, 17 October 1091. It has been reckoned by modern assessment as possibly a T8 on the TORRO scale (roughly equivalent to an F4 on the Fujita scale) making it potentially the strongest recorded tornado in the British Isles, although this estimate is based on reports written 30 years after the tornado. The church of St Mary-le-Bow in the city of London was badly damaged; four rafters long were driven into the ground so that only protruded above the surface. Other churches in the area were demolished, as were over 600 (mostly wooden) houses. For all the damage inflicted, the tornado claimed just two known victims from a population of about 18,000. The tornado is mentioned in chronicles by Florence of Worcester and William of Malmesbury, the latter describing it as "a great spectacle for those watching from afar, but a terrifying experience for those standing near".

Anglo-Saxon Chronicle
The ''Anglo-Saxon Chronicle'' is a collection of annals in Old English, chronicling the history of the Anglo-Saxons. The original manuscript of the ''Chronicle'' was created late in the 9th century, probably in Wessex, during the reign of Alfred the Great (r. 871–899). Multiple copies were made of that one original and then distributed to monasteries across England, where they were independently updated. In one case, the ''Chronicle'' was still being actively updated in 1154. Nine manuscripts survive in whole or in part, though not all are of equal historical value and none of them is the original version. The oldest seems to have been started towards the end of Alfred's reign, while the most recent was written at Peterborough Abbey after a fire at that monastery in 1116. Almost all of the material in the ''Chronicle'' is in the form of annals, by year; the earliest are dated at 60 BC (the annals' date for Caesar's invasions of Britain), and historical material follows up ...

2006 London Tornado
The 2006 London tornado was a significant United Kingdom tornado spawned from a squall line moving over the city on 7 December 2006 at approximately 11:02 GMT. Its intensity is estimated to have been T4 on the TORRO scale, equating to F2 on the Fujita scale. Meteorological synopsis On the morning of 7 December, the UK was under the influence of a strong Atlantic Ocean low pressure system, which was named ''Ulrike'', bringing unstable weather conditions to much of the UK, and the south in particular. At approximately 07:30 GMT, a small band of thunderstorms initialised over Cornwall moving east-northeast across the country. By approximately 10:00 am, the squall line had reached Salisbury, where a drop in humidity was recorded, which may have resulted in an increase of atmospheric pressure behind the squall, causing it to accelerate forward. This increased motion in combination with a change in wind direction ahead of the storm may have initialised the rotation of the mesoc ...

Weather Events In England
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley cell, the Ferrel cell, the polar cell, and the jet stream.

Tornadoes In The United Kingdom
The United Kingdom straddles the higher mid-latitudes between 49° and 61°N on the western seaboard of Europe. Since the UK is always in or close to the path of the polar front jet stream, frequent changes in pressure and unsettled weather are typical. Many types of weather can be experienced in a single day. In general the climate of the UK is changeable, often cloudy especially in the more northerly areas of the country, with rain evenly distributed throughout the year. The climate in the United Kingdom is defined as a oceanic climate, humid temperate oceanic climate, or ''Cfb'' on the Köppen climate classification system, a classification it shares with most of north-west Europe. Regional climates are influenced by the Atlantic Ocean and latitude. Northern Ireland, Wales and western parts of England and Scotland, being closest to the Atlantic Ocean, are generally the mildest, wettest and windiest regions of the UK, and Atmospheric temperature, temperature ranges there are s ...

Medieval Weather Events
In the history of Europe, the Middle Ages or medieval period lasted approximately from the late 5th to the late 15th centuries, similar to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralized authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—most recently part of the Eastern Roman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disasters In London
A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Disasters are routinely divided into either "natural disasters" caused by natural hazards or "human-instigated disasters" caused from anthropogenic hazards. However, in modern times, the divide between natural, human-made and human-accelerated disasters is difficult to draw. Examples of natural hazards include avalanches, flooding, cold waves and heat waves, droughts, earthquakes, cyclones, landslides, lightning, tsunamis, volcanic activity, wildfires, and winter precipitation. Examples of anthropogenic hazards include criminality, civil disorder, terrorism, war, industrial hazards, engineering hazards, power outages, fire, hazards caused by transportation, and environmental hazards. Developing countries suffer the greatest costs wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
11th-century Natural Disasters
The 11th century is the period from 1001 ( MI) through 1100 ( MC) in accordance with the Julian calendar, and the 1st century of the 2nd millennium. In the history of Europe, this period is considered the early part of the High Middle Ages. There was, after a brief ascendancy, a sudden decline of Byzantine power and a rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. Christendom experienced a formal schism in this century which had been developing over previous centuries between the Latin West and Byzantine East, causing a split in its two largest denominations to this day: Roman Catholicism and Eastern Orthodoxy. In Song dynasty China and the classical Islamic world, this century marked the high point for both classical Chinese civilization, science and technology, and classical Islamic science, philosophy, technology and literature. Rival political factions at the Song dynasty court created strife amongst t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
11th Century In London
11 (eleven) is the natural number following 10 and preceding 12. It is the first repdigit. In English, it is the smallest positive integer whose name has three syllables. Name "Eleven" derives from the Old English ', which is first attested in Bede's late 9th-century ''Ecclesiastical History of the English People''. It has cognates in every Germanic language (for example, German ), whose Proto-Germanic ancestor has been reconstructed as , from the prefix (adjectival "one") and suffix , of uncertain meaning. It is sometimes compared with the Lithuanian ', though ' is used as the suffix for all numbers from 11 to 19 (analogously to "-teen"). The Old English form has closer cognates in Old Frisian, Saxon, and Norse, whose ancestor has been reconstructed as . This was formerly thought to be derived from Proto-Germanic (" ten"); it is now sometimes connected with or ("left; remaining"), with the implicit meaning that "one is left" after counting to ten.''Oxford English Dicti ...

Tornado Records
This article lists various tornado records. The most "extreme" tornado in recorded history was the Tri-State Tornado, which spread through parts of Missouri, Illinois, and Indiana on March 18, 1925. It is considered an F5 on the Fujita Scale, even though tornadoes were not ranked on any scale at the time. It holds records for longest path length at , longest duration at about 3½ hours, and fastest forward speed for a significant tornado at anywhere on Earth. In addition, it is the deadliest single tornado in United States history with 695 fatalities. It was also the third most costly tornado in history at the time, but has been surpassed by several others non-normalized. When costs are normalized for wealth and inflation, it still ranks third today. The deadliest tornado in world history was the Daulatpur–Saturia tornado in Bangladesh on April 26, 1989, which killed approximately 1,300 people. In the history of Bangladesh at least 19 tornadoes killed more than 100 people each, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tornado
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The most extreme tornadoes can attain wind speeds of more than , are more than in diameter, and stay on the ground for more than 100&nb ...

William Of Malmesbury
William of Malmesbury ( la, Willelmus Malmesbiriensis; ) was the foremost English historian of the 12th century. He has been ranked among the most talented English historians since Bede. Modern historian C. Warren Hollister described him as "a gifted historical scholar and an omnivorous reader, impressively well versed in the literature of classical, patristic, and earlier medieval times as well as in the writings of his own contemporaries. Indeed William may well have been the most learned man in twelfth-century Western Europe." William was born about 1095 or 1096 in Wiltshire. His father was Norman and his mother English. He spent his whole life in England and his adult life as a monk at Malmesbury Abbey in Wiltshire, England. Biography Though the education William received at Malmesbury Abbey included a smattering of logic and physics, moral philosophy and history were the subjects to which he devoted the most attention. The earliest fact which he records of his caree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
