Peak of Tornado Season: April, May and June Are Most Active and Dangerous Months of Year

April began the most active and dangerous 3 month period with a tornado in the US

Historically, Mei has the maximum number of average tornadoes of 275 people per year. Following this, in June and April an annual average of 215 and 187 tornadoes occurred.

From April to June, the absolute number of tornadoes is not the only time to make this year so dangerous - the intensity of the tornado is also a factor

According to statistics compiled by weather forecaster expert Greg Forbes, approximately 58% of the powerful twisting machine of F3 / EF3 or higher (1950 - 2012) was downgraded in three months. If you check the tornado above F4 / EF4 it will rise to 69%

The strongest F5 / EF5 ratings are assigned to 59 tornados which go back to 1950, and all tornadoes except 10 are occurring in April, May or June.

Although all tornadoes pose a threat, strong tangles can cause more death and damage. According to Forbes, between 2000 and 2013, about 83% of deaths were due to EF 3 or a stronger tornado.

Eight of the 10 most serious tornado outbreaks in the United States occurred in April or May, mainly due to the higher strength of the upper tornado in these months. In addition, during April, May or June, nine out of the ten most serious individual tornadoes lay eggs

The reason that tornadoes are more common in the spring than other moons is that the required atmospheric composition is common during this time of the year.

When the storm system suffers a sudden flow to the south, a tornado occurs when it enters the plain, the Midwest or the south. Flow north towards the Gulf of Mexico with warm and humid air

The jet provides deep wind shear, changes wind speed and wind direction depending on altitude, and supports thunderstorms of rotating supercells

If wind shear is particularly strong at the first few thousand feet near the ground surface, these supercells are more likely to generate tornadoes.

Historically, when entering April, May, June, the greatest threat of tornado thunderstorms moved from the south to a part of the plain and the Midwest.

For example, the possibility of a tornado in the south in June will be much lower than in April. The southern part of spring is rich in water, but it needs to help promote tornado thunderstorms and form a powerful torrent that moves north to the Canadian border.

Most tornadoes occur in relatively flat watersheds between the south and the Rocky Mountains and the Appalachian Mountains, but no countries can not vaccinate. Peak months of tornado activities in the US are April, May and June. However, tornadoes occur every month and occur every day or night. Typical occurrence time is warm, hot and humid spring afternoon, and it is not seasonal between 3 pm. A tornado occurred at 9 pm under certain weather conditions and three very different types of air were gathered in some way. Near the ground, there is a strong warm moist air of the south wind. Cold air and strong west or southwest wind are in the upper atmosphere. The difference between temperature and humidity between the surface and the upper layer creates what is called unstable. It is an essential element in the formation of a tornado. Wind speed and wind direction vary with height

The tornado season usually refers to the time when the United States is watching most tornadoes. The peak period of the "tornado season" in the southern plain is from May to the beginning of June. On the Gulf, at the beginning of spring. In the northern plains and the upper part of the Midwest, the tornado season is June or July. However, please be aware that tornadoes can occur at any time of the year. Tornados can also happen at any time of day or night, but most tornadoes will occur between 4 pm and 9 pm. Meteorologists at NOAA 's Storm Forecast Center have announced the tornado clock that they are seeing weather conditions throughout the U.S, it is suitable for tornadoes. A watch can cover a part of one or more states. Monitor and prepare bad weather, and enjoy NOAA weather broadcasts to see when warnings are issued
