Tornadoes can occur almost anywhere, but they tend to be more common and more destructive in some areas than in others. Since tornadoes are a weather phenomenon, their prevalence is largely controlled by a region's climate. A region must have the right combination of moisture, instability, wind shear, and weather systems to trigger severe storms.

Tornadoes can occur in many parts of the world, not just in Tornado Alley in the central United States. They can form in any region where the right atmospheric conditions are present, although Tornado Alley does have a higher frequency of tornadoes.
Meteorologists can forecast the potential for tornadoes to occur in a given area based on weather conditions, but predicting the exact location and timing of a tornado is extremely challenging. Tornadoes are small and short-lived, making them difficult to predict with certainty. Current technology and understanding of tornado formation have limitations in providing accurate forecasts at a specific time and place.
On average, there are about 1,000 tornadoes reported each year worldwide. However, the actual number could be higher as not all tornadoes are observed and reported. The United States experiences the most tornadoes of any country, with an average of about 1,250 tornadoes annually.
Tornadoes can occur at any time of day, but they may seem more common during late afternoon and early evening due to favorable atmospheric conditions. For example, daytime heating can lead to instability in the atmosphere, while the evening hours can see the convergence of different air masses, providing the necessary ingredients for tornado formation.
Yes, tornadoes can occur even when the sun is out. Tornadoes form when certain weather conditions are present, such as warm, moist air colliding with cool, dry air. These conditions can occur regardless of whether the sun is shining or not.
