Tornado Outbreak Sequence Of March 18–24, 2012
The Tornado outbreak sequence of March 18–24, 2012 was a long lasting tornado outbreak that occurred due to a slow moving, but powerful trough and cutoff low. The outbreak began in the Great Plains, where, over a two-day period, several tornadoes touched down, some of which were significant. The North Platte area was damaged by an EF3 that was produced by a supercell that spawned many tornadoes throughout its lifespan. The tornadic activity then shifted the Southern United States over subsequent days, particularly in Louisiana and Mississippi. These states were struck by a series of tornadoes for 3 days, most of which were relatively weak on the Enhanced Fujita Scale. However, a few reached EF2 intensity and caused considerable damage. Tornado activity continued across the Ohio Valley on the 23rd, with one confirmed fatality in southern Illinois. Meteorological synopsis March 18–19 March 20–22 March 23–24 A slight risk was issued for parts of the Ohio Valley, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed Isobar (meteorology), isobaric contour that would define it as a Low-pressure area, low pressure area. Since low pressure implies a low Geopotential height, height on a pressure surface, Valley, troughs and Ridge (meteorology), ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft, at altitude. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect Cyclonic rotation, cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions ...

Enhanced Fujita Scale
The Enhanced Fujita scale (abbreviated EF-Scale) is a scale that rates tornado intensity based on the severity of the damage a tornado causes. It is used in the United States and France, among other countries. The EF scale is also unofficially used in other countries, including China and Brazil. The rating of a tornado is determined by conducting a tornado damage survey. The scale has the same basic design as the original Fujita scale—six intensity categories from zero to five, representing increasing degrees of damage. It was revised to reflect better examinations of tornado damage surveys, in order to align wind speeds more closely with associated storm damage. Better standardizing and elucidating what was previously subjective and ambiguous, it also adds more types of structures and vegetation, expands degrees of damage, and better accounts for variables such as differences in construction quality. An "EF-Unknown" (EFU) category was later added for tornadoes that cannot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
