Bow Echo
A bow echo is the characteristic radar return from a mesoscale convective system that is shaped like an archer's bow. These systems can produce severe straight-line winds and occasionally tornadoes, causing major damage. They can also become derechos or form Line echo wave pattern (LEWP). Research The term "bow echo" was first used by Theodore Fujita in his May 1978 paper "Manual of Downburst Identification for Project NIMROD." In 2004, research was done to better anticipate the formation of bow echoes, specifically the formation of bow echoes from weakly organized squall lines and supercells. Researchers determined that bow echoes were most likely to occur in weakly organized cells. A Midwest Bow Echo Workshop was held in 2007, at which meteorologists gathered to share their research to better understand bow echoes. Formation A bow echo is associated with squall lines or lines of convective thunderstorms. These echoes can range in size from 20 to 200 km, and hav ...

Gustnado
A gustnado is a brief, shallow surface-based vortex which forms within the downburst emanating from a thunderstorm. The name is a portmanteau by elision of "gust front tornado", as gustnadoes form due to non-tornadic straight-line wind features in the downdraft (outflow (meteorology), outflow), specifically within the gust front of strong thunderstorms. Gustnadoes tend to be noticed when the vortices loft sufficient debris or form condensation cloud to be visible although it is the wind that makes the gustnado, similarly to tornadoes. As these Eddy (fluid dynamics), eddies very rarely connect from the surface to the cloud base, they are very rarely considered as tornadoes. The gustnado has little in common with tornadoes structurally or dynamically in regard to vertical development, Tornado intensity, intensity, longevity, or Tornadogenesis, formative process—as classic tornadoes are associated with mesocyclones within the inflow (meteorology), inflow (updraft) of the storm, not ...

2024 São Paulo Storm
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava The Pallava dynasty existed from 275 CE to 897 CE, ruling a significant portion of South India, the Deccan, also known as Tondaimandalam. The Pallavas played a crucial role in shaping in particular southern Indian history and heritage. The ... evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to th ...

Hailstorm Piracicaba 2024-10-11
Hail is a form of solid precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures. Unlike other forms of water ice precipitation, such as graupel (which is made of rime ice), ice pellets (which are smaller and translucent), and snow (which consists of tiny, delicately crystalline flakes or needles), hailstones usually measure between and in diameter. The METAR reporting code for hail or greater is GR, while smaller hailstones and graupel are coded GS. Hail is possible during most thunderstorms (as it is produced by cumulonimbus), as well as within of the parent storm. Hail formation requires environments of strong, upward motion of air within the parent thunderstorm (similar to tornadoes) and lowered heights of the freezing le ...

Metropolitan Regions In Germany
There are eleven metropolitan regions in Germany consisting of the country's most densely populated cities and their catchment areas. They represent Germany's political, commercial and cultural centres. The eleven metropolitan regions in Germany were organised into political units for planning purposes. Based on a narrower definition of metropolises commonly used to determine the metropolitan status of a given city, only four cities in Germany surpass the threshold of at least one million inhabitants within their administrative borders: Berlin, Hamburg, Munich, and Cologne. For urban centres outside metropolitan areas that are a similar focal point for their region, but on a smaller scale, the concept of the Regiopolis and the related concepts of ''regiopolitan area'' or ''regio'' were introduced by urban and regional planning professors in 2006.

2014 Pentecost Weekend Storms In Europe
The 2014 Pentecost weekend storms in Europe were a series of intense supercells and Mesoscale convective system, MCSs affecting western and central Europe, which followed a heatwave in early June 2014, resulting from a Spanish plume Synoptic scale meteorology, synoptic weather pattern. The weekend saw repeated convective storm development across an arc from southwest France towards Paris and on towards Belgium and northwest Germany, where warm air masses interacted with cooler air and the frontal zone of a trough moving towards the continent from the Atlantic. Outbreaks of severe weather associated with this system spanned over 5 days from June 6 to June 11, with the worst damage occurring in the German state of on 9 June, where the storm was described as one of the most violent in decades by the German Weather Service (Deutscher Wetterdienst). The responsible low pressure system is also referred to as storm "Ela" in some German media. Synoptic situation On June 4, a small low pre ...
