Where do thunderstorms form most frequently in the U.S.? Why is this the case??
What will be the ideal response?
ANSWER: In the United States thunderstorms occur most frequently in the southeastern United States along the Gulf Coast, with a maximum in Florida. The region with the fewest thunderstorms is the Pacific coastal and interior valleys. The reason for this distribution is that the combination of warmth and moisture make equatorial landmasses especially conducive to thunderstorm formation. Here, thunderstorms occur on about one out of every three days. Thunderstorms are also prevalent over water along the intertropical convergence zone, where the low-level convergence of air helps to initiate uplift. Thunderstorms are much less prevalent in dry climates, such as the polar regions and the desert areas dominated by subtropical highs.?
