For example, the potential for tornadoes in the South is much lower in June compared to April. Although moisture is abundant across the southern U. By the summer, tornadoes can occur virtually anywhere nationwide because warmth and humidity are the most widespread of any time of the year. A secondary peak in tornado activity occurs in the fall in the Gulf Coast states, but this activity can sometimes spread northward to the Ohio Valley and southern Great Lakes.
From late fall through the winter, the greatest chance of tornadoes moves back to the South with the warmest air and much of the moisture. Click through the slideshow below to see where the average tornado risk area is during each month. This story does not necessarily represent the position of our parent company, IBM. Daily 11 Today. Surprisingly, it caused more fatalities than injuries.
Nevertheless, many historians believe that the death toll was much larger, seeing how slave deaths were unaccounted for. On the other hand, the St Louis storm hit Missouri and Illinois, leading to a death toll of at least Lastly, the Tupelo tornado in Mississippi led to some fatalities and the destruction of 48 city blocks, as reported by tornado death statistics of the area.
Likewise, F0 tornadoes cause light damage and have an average wind speed between 40—72mph. F1 are moderate storms and feature 73—mph wind speeds, followed by F2 storms causing considerable damage with —mph wind speeds. In addition, F3 storms are regarded as severe —mph , F4 storms are devastating —mph , and F5 tornadoes are the most deadly with wind speeds ranging between an incredible —mph!
According to Dr. Currently, climatologists are studying slow-motion drivers that could cause storms in the summer and autumn of Even though this number may seem like a lot, the year-over-year stats tell a different story.
Even though there was a noticeable decrease in the number of tornadoes in , the US has witnessed the highest number of tornado deaths since Researchers are blaming economic development and population growth as the leading cause of the damage caused by tornadoes. However, scientists have also found that the intensity and frequency of these storms is also changing.
Tornadoes appear as rotating, conical clouds that typically extend from thunderstorms to the ground with wind speeds of up to miles per hour. According to experts, out of the average 1, tornadoes that hit the United States every year, at least 20 are expected to reach over mph. The damage paths tend to be anywhere between 1 to 50 miles long. How wide are tornadoes? Tornadoes can be more than one mile wide and stay on the ground for over 50 miles.
In the US, there are 2 regions that report the highest frequency of tornadoes. One of them is Florida. This area produces the ideal environment for severe thunderstorms and the majority of the storms are caused when the dry and cold air from Canada meets the warm and moist air from the Gulf of Mexico.
In other words, if a tornado watch is issued, people must take the necessary precautions, these include taking shelter and preparing for all the possible consequences associated with these storms.
This sum was caused by a total of 56 severe thunderstorms that took place throughout To put things into perspective, only 5 tropical cyclones took place, yet their impact was indeed noticed — people perished as a result of these natural phenomenons.
Tornadoes remain largely unpredictable and difficult to deal with. Occurrence rates are volatile from a year-to-year standpoint, meaning that people often find it difficult to prepare. Luckily, the number of deaths worldwide is decreasing thanks to public institutions having improved their disaster relief protocols. Despite this, a few dozen people still perish on a yearly basis. Tornadoes are not exclusive to specific locations; therefore, they can occur practically anywhere in the world. Nevertheless, studies and statistics on the matter suggest that some areas are more prone to being struck by tornadoes than others.
Such is the case with the US more specifically, the Great Plains in the central region of the country, an area commonly referred to as Tornado Alley , or the case with Bangladesh and Argentina, as reported by various tornadoes statistics by state and country.
Southern states such as Tennessee, Kentucky and Arkansas also see more tornadoes overnight versus any other state.
This can lead to higher fatalities, since many people are sleeping and unaware that a tornado is approaching. Southeastern tornadoes often travel faster, moved by a faster jet stream. All of these factors can lead to higher fatality rate in Southern states compared to the Plains.
But all of these states have a few things in common: the ideal atmospheric conditions for tornadoes to form. Low pressure systems in the US pull warm, moist air from the Gulf of Mexico and cool, dry air aloft from the Rocky Mountains or the High Desert in the southwest. The states that fall in between those two regions end up being in the ideal location for severe weather to ignite.
Brooks said. Europe as a whole is comparable to the size of the US, but there is a vast difference in number of tornadoes and tornado fatalities. From to , the US averaged a preliminary total of 1, tornadoes per year, and Europe around However, Dr.
European Russia which is the part of the country west of 58 degrees East longitude , tops the list at 86 tornadoes annually. Germany comes in second with an average 28 tornadoes annually. The peak density of tornado reports coincides with the high population density over Belgium, the Netherlands, and northern Germany, according to a study on severe storms in Europe published in December The study also reports that thunderstorms are twice as frequent over the United States, with as many as four times more storm reports, compared to Europe.
One thing most countries have in common is the time of day that tornadoes occur, which is most frequently during the afternoon and early evening. Each of these states sees 15 or more tornadoes in the average May. At least the second best month for storm chasing.
This can be an active Chicago to East Coast month as well. All see 15 or more tornadoes in June on average.
This is another month which tends to target the northeast U. August is kind of like a deflated July. There are often tornadoes all over the place, just not many in one spot. They all see four or more tornadoes when their numbers are rounded. September features 66 tornadoes on average, usually continuing the August deflation. It also shows the beginning of a southward constriction back toward the Gulf warmth headed to winter. The top five states for September tornadoes all see four or more when their averages are rounded.
Tornadoes continue to wane into October, but much of the nation has still been impacted during the month. There are 58 tornadoes in October on average, and the Plains into the South become a favored zone once again. Each sees three of more tornadoes on average.
