pos: Tornadoes in the United States Tornadoes in the United States Tornadoes are more common in United States than in any other country. The United States receives more than 1,200 tornadoes annually—four times the amount seen in Europe. Violent tornadoes—those rated EF4 or EF5 on the Enhanced Fujita Scale—occur more often in the United States than in any other country. Most tornadoes in the United States occur east of the Rocky Mountains. The Great Plains, the Midwest, the Mississippi Valley and the southern United States are all areas that are vulnerable to tornadoes. They are relatively rare west of the Rockies and are also less frequent

However, these deadly and destructive storms do occur; on average, about eight tornadoes are reported in the region each year. Almost 200 people have been killed by these storms in recorded history, and two of the ten most destructive tornadoes in US history occurred in this region. Tornadoes are a violent weather phenomenon that occur most often in the United States, to the east of the Rocky Mountains. However, they most often

As in the US, tornadoes are far from evenly distributed. Europe has some small "tornado alleys" – probably because of frontal collisions as in the south and east of England, but also because Europe is partitioned by mountain ranges like the Alps.

On average, there are around 294 tornadoes throughout the United States during the month of May, and as many as 543 tornadoes have been reported in the month of May alone (in 2003). The months with the fewest tornadoes are usually December and January, although major tornado outbreaks can and sometimes do occur even in those months.

Anticyclonic tornadoes often occur; while tornadoes' vortices are low-pressure regions, this occurs because tornadoes occur on a small enough scale such that the Coriolis effect is negligible. Anticyclonic storm An anticyclonic storm is a weather storm where winds around the storm flow in the direction opposite to that of the flow about a region of low pressure. In the Northern Hemisphere, anticyclonic storms involve clockwise wind flow; in the Southern Hemisphere, they involve counterclockwise wind flow. Anticyclonic storms usually form around high-pressure systems. These do not "contradict" the Coriolis effect; it predicts such anticyclonic flow about high-pressure regions. Anticyclonic

Much of Huntsville's precipitation is delivered by thunderstorms. Thunderstorms are most frequent during the spring, and the most severe storms occur during the spring and late fall. These storms can deliver large hail, damaging straight-line winds, and tornadoes.

Bangladesh and surrounding areas of eastern India suffer from a couple tornadoes annually of similar severity to stronger tornadoes in the US. These occur with a greater recurrence interval (although over a smaller region), and tend to be under-reported due to the scarcity of media coverage of a developing country. The annual human death toll from tornadoes in Bangladesh is estimated at about 179 deaths per year, which is much greater than in the US. This is likely due to the density of population,

Large tornadoes tend to come from larger, lower wall clouds closer to the back of the rain curtain (providing less visual warning time to those in the path of an organized storm). Although it is rotating wall clouds that contain most strong tornadoes, many rotating wall clouds do not produce tornadoes. Absent the co-position of a low-level boundary with an updraft, tornadoes very rarely occur without a sufficiently buoyant rear flank downdraft (RFD), which usually manifests itself visually as a drying out of clouds, called a clear slot or notch. The RFD initiates the tornado, occludes around

Satellite tornadoes occur apart from the primary tornado and are not considered subvortices; the primary tornado and satellite tornadoes are considered to be separate tornadoes. The cause of satellite tornadoes is not known. Such tornadoes are more often anticyclonic than are typical tornadoes and these pairs may be referred to as tornado couplets. Satellite tornadoes most commonly form in association with very large and intense tornadoes. Satellite tornadoes are relatively uncommon. When a satellite tornado does occur there is

Other myths are that tornadoes can skip houses, always travel in a predictable direction, always extend visibly from the ground to the cloud, and increase in intensity with increasing width. Finally, some people believe that tornadoes only occur in North America, do not occur in winter, are attracted to trailer park homes, or that some areas are protected from tornadoes by rivers, mountains, valleys, tall buildings or other geographical or man-made features; the truth is that tornadoes can

Thunderstorm activity in the state is highest during the late spring and early summer. The southeastern corner of the state is the most vulnerable part of the state to tornado activity.

Tornadoes, where they occur, tend to be small and brief, unlike some of those that occur a little farther

This is in part due to the relatively high number of strong/violent long tracked tornadoes and higher population density of this region, as well as the Southern United States having the highest percentage of manufactured homes in the US, where 63% of the overall tornado-related fatalities occur. According to the National Climatic Data Center, for the period January 1, 1950 – October 31, 2006, Alabama and Kansas received the largest amount of F5 tornadoes. Complicating matters is that tornadoes are rarely visible in this area, as they are more likely to be rain-wrapped, embedded in shafts

Because spring is a transitional period for the climate, there are more chances of cooler air meeting with warmer air, resulting in more thunderstorms. Tornadoes can also be spawned by landfalling tropical cyclones, which usually occur in late summer and autumn. In the United States, thunderstorms capable of producing tornadoes usually form when the temperature is at its highest, typically from 4:00 p.m. to 7:00 p.m. Although the period in which most tornadoes strike ("tornado season") is March through June, tornadoes

Waterspouts typically do not do much damage because they occur over open water, but they are capable of traveling over land. Vegetation, weakly constructed buildings, and other infrastructure may be damaged or destroyed by waterspouts. Waterspouts do not generally last long over terrestrial environments as the friction produced easily dissipates the winds. Strong horizontal

Radar analysis of the velocity couplet as well as the automated TVS are very significant to issuing tornado warnings and can suggest the strength and location of possible tornadoes.

Strong straight-line winds can occur where the squall line is in the shape of a bow echo.

A mixed convective mode was predicted, with both bowing line segments and discrete supercell thunderstorms expected to develop in the threat area. Throughout the event, the development of isolated supcercell thunderstorms that was expected did not occur. However, a large quasi-linear convective system developed, and numerous semi-discrete supercell structures and embedded mesovortices within the larger line of severe storms produced a moderate outbreak of tornadoes. While most of these tornadoes were relatively brief, several of them were strong, resulting in major damage and fatalities. A high-end EF2 tornado near Adairville, Kentucky destroyed several
