No. Tornadoes cannot affect areas that don't have tornadoes. However, tornadoes can occur in more places than many people realize. It is not uncommon for people to think that tornadoes don't occur in their areas when, in fact, they do. This is a result of a few factors. First, although tornadoes can occur in most places on earth, they are quite rare in many areas. Second, many tornadoes are relatively weak and cause only minor to moderate damage and so are less reported than the EF4s and EF5s that level whole neighborhoods. Third, may people to not pay close enough attention to events and are quick to forget many events.
Tornadoes can destroy vegetation, especially in forested areas and destroy habitats.
Yes. Population density does not affect the likelihood of a tornado striking. Many tornadoes have hit cities.
How often tornadoes occur in different regions is a function of climate. Tornadoes are weather events and climate is the long-term behavior of the weather. In simple terms, tornadoes occur in areas whose climates support the formation of strong thunderstorms and wind shear.
This means that there is a chance of tornadoes occurring in a few isolated areas. It suggests that tornadoes may form sporadically and not affect a wide area. Residents in the affected areas should stay alert and be prepared to take necessary safety precautions.
The tornadoes most common in the southeast quadrant of the US are often referred to as "Dixie Alley" tornadoes. These tornadoes typically occur during the late fall through early spring and can be particularly dangerous due to the densely populated areas they affect.
No. Like virtually all stormy weather, tornadoes are associated with low pressure areas. Tornadoes themselves produce intense low pressure.
Hurricanes cover large areas. Tornadoes are much smaller.
No.
Tornadoes don't occur in Antarctica or in areas of extreme desert.
No. While tornadoes are more common in warm areas, they have been spotted as far north as Alaska.
Tornadoes can occur in most climates, but are more common in areas with hot climates. However, temperature is not the only factors. Tornadoes are rare in arid regions, for example.
No, they do not. Relatively few tornadoes hit downtown areas simply becuase such areas make up an incredibly small portion of land in the U.S.
