why do tornadoes occur in the spring
Why Do Most Tornado Outbreaks Happen in the Spring? Why Do Most Tornado Outbreaks Happen in the Spring? Even though tornadoes are chaotic and unpredictable, they tend to have their peak season when the weather is changing. P When cold air mixes with warm air, conditions are more favorable for supercell storms which can spawn tornadoes. P It is this instability in the atmosphere which wreaks havoc throughout tornado alley. PThe breakdown in atmosphere can cause tornadoes to become more prevalent. P As the U. S. weather patterns begin to change, and where April showers bring May flowers, keep in mind the importance of watching and listening to the weather. The eastern half of the United States is typically the hardest hit with the most tornado outbreaks. However, that is not to say tornadoes cannot strike anywhere. PIn fact, Alaska is the only state to have a long-term annual average of 0 tornadoes, even though tornadoes have been spotted there in the past.
P Meanwhile, Texas, Kansas, and Oklahoma rank as the top 3 states for tornadoes, in that order. P So, while tornadoes can seem to strike anywhere at any time, it is the beautiful days of spring and even the fall. PTypically, when weather patterns are changing, thunderstorms are more common. P Always be aware, and always be prepared. You should have a family safety action plan in place and ready for when you need it.
Tornado occurrence is highly dependent on the time of day. Austria, Finland, Germany, and the United States' peak hour of occurrence is 5Ppm, with roughly half of all tornado occurrence between 3 p. m. and 7 p. m. local time, due to this being the time of peak atmospheric heating, and thus the maximum available energy for storms; some researchers, including of the, have referred to this phenomenon as "five o'clock magic. " Despite this, there are several morning tornadoes reported, like the, Texas one in April 1980. The time of year is a big factor of the intensity and frequency of tornadoes.
On average, in the United States as a whole, the month with the most tornadoes is May, followed by the months June, April, and July. There is no "tornado season" though, as tornadoes, including violent tornadoes and major outbreaks, can and do occur anywhere at any time of year if favorable conditions develop. Major tornado outbreaks have occurred in every month of the year. July is the peak month in Austria, Finland, and Germany. 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. In general, in the Midwestern and Plains states, springtime (especially the month of May) is the most active season for tornadoes, while in the far northern states (like and ), the peak tornado season is usually in the summer months (June and July).
In the colder late autumn and winter months (from early December to late February), tornado activity is generally limited to the southern states, where it is possible for warm Gulf of Mexico air to penetrate. The reason for the peak period for tornado formation being in the spring has much to do with temperature patterns in the U. S. Tornadoes often form when cool, polar air traveling southeastward from the Rockies overrides warm, moist, unstable air in the eastern states. Tornadoes therefore tend to be commonly found in front of a cold front, along with heavy rains, hail, and damaging winds. Since both warm and cold weather are common during the springtime, the conflict between these two air masses tends to be most common in the spring. As the weather warms across the country, the occurrence of tornadoes spreads northward.
Tornadoes are also common in the summer and early fall because they can also be triggered by hurricanes, although the tornadoes caused by hurricanes are often much weaker and harder to spot. Winter is the least common time for tornadoes to occur, since hurricane activity is virtually non-existent at this time, and it is more difficult for warm, moist maritime tropical air to take over the frigid Arctic air from Canada, occurrences are found mostly in the Gulf states and Florida during winter (although there have been some notable exceptions). Interestingly, there is a second active tornado season of the year, late October to mid-November. Autumn, like spring, is a time of the year when warm weather alternates with cold weather frequently, especially in the Midwest, but the season is not as active as it is during the springtime and tornado frequencies are higher along the Atlantic Coastal plain as opposed to the Midwest. They usually appear in late summer.
