Guerrilla Rainstorm
A is a Japanese expression used to describe a short, localized downpour of over 100 mm per hour of rain caused by the unpredictable formation of a cumulonimbus cloud. The term is often used by the Japanese media in reporting such events, but does not have an official meaning nor is it used by the Japan Meteorological Agency. History of usage The first example of the term being used was by the ''Yomiuri Shimbun'' in August 1969. It carries the same meaning as the term , but is differentiated by the added feature of being difficult to forecast, hence the reference to the aspect of ambush associated with the term guerrilla warfare. Neither "guerrilla rainstorm" nor "cloudburst" is a defined term used by the meteorological agency, which instead uses the term . Usage of the term spread in the private media from 2006.

Rain
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cumulonimbus Cloud
Cumulonimbus (from Latin ''cumulus'', "heaped" and ''nimbus'', "rainstorm") is a dense, towering vertical cloud, typically forming from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents. Above the lower portions of the cumulonimbus the water vapor becomes ice crystals, such as snow and graupel, the interaction of which can lead to hail and to lightning formation, respectively. When occurring as a thunderstorm these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along squall lines. These clouds are capable of producing lightning and other dangerous severe weather, such as tornadoes, hazardous winds, and large hailstones. Cumulonimbus progress from overdeveloped cumulus congestus clouds and may further develop as part of a supercell. Cumulonimbus is abbreviated Cb. Appearance Towering cumulonimbus clouds are typically accompanied by smaller cumulus clouds. The cumulonimbus bas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan Meteorological Agency
The , abbreviated JMA, is an agency of the Ministry of Land, Infrastructure, Transport and Tourism. It is charged with gathering and providing results for the public in Japan that are obtained from data based on daily scientific observation and research into natural phenomena in the fields of meteorology, hydrology, seismology and volcanology, among other related scientific fields. Its headquarters is located in Minato, Tokyo. JMA is responsible for gathering and reporting weather data and forecasts for the general public, as well as providing aviation and marine weather. JMA other responsibilities include issuing warnings for volcanic eruptions, and the nationwide issuance of earthquake warnings of the Earthquake Early Warning (EEW) system. JMA is also designated one of the Regional Specialized Meteorological Centers of the World Meteorological Organization (WMO). It is responsible for forecasting, naming, and distributing warnings for tropical cyclones in the Northwestern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yomiuri Shimbun
The (lit. ''Reading-selling Newspaper'' or ''Selling by Reading Newspaper'') is a Japanese newspaper published in Tokyo, Osaka, Fukuoka, and other major Japanese cities.

Cloudburst
A cloudburst is an extreme amount of precipitation in a short period of time, sometimes accompanied by hail and thunder, which is capable of creating flood conditions. Cloudbursts can quickly dump large amounts of water, e.g. 25 mm of precipitation corresponds to 25,000 metric tons per square kilometre (1 inch corresponds to 72,300 short tons over one square mile). However, cloudbursts are infrequent as they occur only via orographic lift or occasionally when a warm air parcel mixes with cooler air, resulting in sudden condensation. At times, a large amount of runoff from higher elevations is mistakenly conflated with a cloudburst. The term "cloudburst" arose from the notion that clouds were akin to water balloons and could burst, resulting in rapid precipitation. Though this idea has since been disproven, the term remains in use. Properties Rainfall rate equal to or greater than per hour is a cloudburst. However, different definitions are used, e.g. the Swedish weat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambush
An ambush is a long-established military tactics, military tactic in which a combatant uses an advantage of concealment or the element of surprise to attack unsuspecting enemy combatants from concealed positions, such as among dense underbrush or behind mountaintops. Ambushes have been used consistently throughout history, from ancient warfare, ancient to modern warfare. In the 20th century, an ambush might involve thousands of soldiers on a large scale, such as over a choke point such as a mountain pass, or a small irregulars band or insurgent group attacking a Regular army, regular armed force patrols. Theoretically, a single well-armed and concealed soldier could ambush other troops in a surprise attack. Sometimes an ambush can involve the exclusive or combined use of improvised explosive devices, that allow the attackers to hit enemy convoys or patrols while minimizing the risk of being exposed to return fire. History This use by early people of ambushing may date as far ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guerrilla Warfare
Guerrilla warfare is a form of irregular warfare in which small groups of combatants, such as paramilitary personnel, armed civilians, or Irregular military, irregulars, use military tactics including ambushes, sabotage, Raid (military), raids, petty warfare, hit-and-run tactics, and Mobility (military), mobility, to fight a larger and less-mobile traditional military. Although the term "guerrilla warfare" was coined in the context of the Peninsular War in the 19th century, the tactical methods of guerrilla warfare have long been in use. In the 6th century BC, Sun Tzu proposed the use of guerrilla-style tactics in ''The Art of War''. The 3rd century BC Roman general Quintus Fabius Maximus Verrucosus is also credited with inventing many of the tactics of guerrilla warfare through what is today called the Fabian strategy. Guerrilla warfare has been used by various factions throughout history and is particularly associated with revolutionary movements and popular resistance agains ...

Climate Of Japan
Most regions of Japan, such as much of Honshu, Shikoku and Kyushu, belong to the temperate zone with humid subtropical climate (Köppen climate classification ''Cfa'') characterized by four distinct seasons. However, its climate varies from cool humid continental climate (Köppen climate classification ''Dfb'') in the north such as northern Hokkaido, to warm tropical rainforest climate (Köppen climate classification ''Af'') in the south such as the Yaeyama Islands and Minami-Tori-shima. Climate zones Japan's varied geographical features divide it into six principal climatic zones. * Hokkaido belongs to the humid continental climate, with long, cold winters and cool summers. Precipitation is sparse; however, winter brings large snowfalls of hundreds of inches in areas such as Sapporo and Asahikawa. * In the Sea of Japan, the northwest seasonal wind in winter gives heavy snowfall, which south of Tōhoku mostly melts before the beginning of spring. In summer, it is a little les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
