Cumulonimbus Arcus
An arcus cloud is a low, horizontal cloud formation, usually appearing as an accessory cloud to a cumulonimbus. Roll clouds and shelf clouds are the two main types of arcus clouds. They most frequently form along the leading edge or gust fronts of thunderstorms; some of the most dramatic arcus formations mark the gust fronts of derecho-producing convective systems. Roll clouds may also arise in the absence of thunderstorms, forming along the shallow cold air currents of some sea breeze boundaries and cold fronts. Types Shelf cloud A shelf cloud is a low, horizontal, wedge-shaped arcus cloud. A shelf cloud is attached to the base of the parent cloud, which is usually a thunderstorm cumulonimbus, but could form on any type of convective clouds. Rising cloud motion can often be seen in the leading (outer) part of the shelf cloud, while the underside can often appear as turbulent and wind-torn. Cool, sinking air from a storm cloud's downdraft spreads out across the land surface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Squall
A squall is a sudden, sharp increase in wind speed lasting minutes, as opposed to a wind gust, which lasts for only seconds. They are usually associated with active weather, such as rain showers, thunderstorms, or heavy snow. Squalls refer to the increase of the sustained winds over that time interval, as there may be higher gusts during a squall event. They usually occur in a region of strong sinking air or cooling in the mid-atmosphere. These force strong localized upward motions at the leading edge of the region of cooling, which then enhances local downward motions just in its wake. Etymology There are different versions of the word's origins: * By one version, the word appears to be Nordic in origin, but its etymology is considered obscure. It probably has its roots in the word ''skvala'' an Old Norse word meaning literally ''to squeal''. * By another version, it is an alteration of ''squeal'' influenced by ''bawl''.

Mesoscale Meteorology
Mesoscale meteorology is the study of weather systems smaller than synoptic scale systems but larger than Microscale meteorology, microscale and storm-scale cumulus systems. Horizontal dimensions generally range from around 5 kilometers to several hundred kilometers. Examples of mesoscale weather systems are sea breezes, squall lines, and mesoscale convective complexes. Vertical velocity often equals or exceeds horizontal velocities in mesoscale meteorological systems due to nonhydrostatic processes such as buoyant acceleration of a rising thermal or acceleration through a narrow mountain pass. Subclasses Mesoscale Meteorology is divided into these subclasses: * Meso-alpha 200–2000 km scale of phenomena like fronts, squall lines, mesoscale convective systems (MCS), tropical cyclones at the edge of synoptic scale * Meso-beta 20–200 km scale of phenomena like sea breezes, lake effect snow storms * Meso-gamma 2–20 km scale of phenomena like thunderstorm convectio ...

Soliton
In mathematics and physics, a soliton or solitary wave is a self-reinforcing wave packet that maintains its shape while it propagates at a constant velocity. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. (Dispersive effects are a property of certain systems where the speed of a wave depends on its frequency.) Solitons are the solutions of a widespread class of weakly nonlinear dispersive partial differential equations describing physical systems. The soliton phenomenon was first described in 1834 by John Scott Russell (1808–1882) who observed a solitary wave in the Union Canal in Scotland. He reproduced the phenomenon in a wave tank and named it the "Wave of Translation". Definition A single, consensus definition of a soliton is difficult to find. ascribe three properties to solitons: # They are of permanent form; # They are localized within a region; # They can interact with other solitons, and emerge from the collision unchanged, e ...

Enschede
Enschede (; known as in the local Twents dialect) is a municipality and city in the eastern Netherlands in the province of Overijssel and in the Twente region. The eastern parts of the urban area reaches the border of the German city of Gronau. The municipality of Enschede consisted of the city of Enschede until 1935, when the rural municipality of Lonneker, which surrounded the city, was annexed after the rapid industrial expansion of Enschede which began in the 1860s and involved the building of railways and the digging of the Twentekanaal. The proposal for consolidation began in 1872, per the Tubantia newspaper article on 22 June 1872 that referenced a committee of 5 to oversee a study. They were: J. Mosman (Johannes Theodorus Mosman), H. Fikkert, H. G. Blijdenstein J. Bz., C. C. Schleucker, and G. J. van Heek. In sports and culture, Enschede is known for being home to football club FC Twente, one-time Dutch champions, and the University of Twente. The municipality of ...

Puducherry (union Territory)
Puducherry (), also known as Pondicherry () or Pondichéry, is a union territory of India, consisting of four small geographically unconnected districts. It was formed out of four territories of former French India, namely Pondichéry (Pondicherry; now Puducherry), Karikal (Karaikal), Mahé and Yanaon (now Yanam), excluding Chandannagar (Chandernagore), and it is named after the largest district, Puducherry, which was also the capital of French India. Historically known as Pondicherry (), the territory changed its official name to Puducherry on 20 September 2006. The Union Territory of Puducherry lies in the southern part of the Indian Peninsula. The areas of Puducherry district and Karaikal district are bound by the state of Tamil Nadu, while Yanam district and Mahé district are enclosed by the states of Andhra Pradesh and Kerala, respectively. Puducherry is the 29th most populous of the 36 states and union territories of India, and the third most densely populated ...

Pondicherry
Pondicherry (), now known as Puducherry ( French: Pondichéry ʊdʊˈtʃɛɹi(listen), on-dicherry, is the capital and the most populous city of the Union Territory of Puducherry in India. The city is in the Puducherry district on the southeast coast of India and is surrounded by Bay of Bengal to the east and the state of Tamil Nadu, with which it shares most of its culture, heritage, and language. History Puducherry, formerly known as Pondicherry, gained its significance as “The French Riviera of the East” after the advent of the French colonialization in India. Puducherry is the Tamil interpretation of “new town” and mainly derived from “Poduke”, the name of the marketplace as the “Port town” for Roman trading in 1st century as mentioned in ‘The Periplus of the Erythraean Sea’. The settlement was once an abode of many learned scholars as evidently versed in the Vedas, hence also known as Vedapuri. The history of Puducherry can broadly be classified ...
