Does anyone no any facts on tornadoes ?
Tornadoes can travel at any speeds. The average foreward motion of a tornado is between 25-35 mph, however, speeds can vary from stationary to as much as 65-70 mph! The average direction a tornado travels is from Southwest to Northeast but again tornadoes can travel in any direction. Tornadoes are most likely to strike areas to the East of the Rocky Mountains and to the West of the Appalachians. However, tornadoes can strike anywhere in the United States and in the world (except Antarctica and North Pole). For tornadoes to form you need warm moist air at the surface and cold dry air aloft. The warm moist air rides Northward from the Gulf of Mexico and the cool dry air comes in from Canada or from air traveling over the Rocky Mountains. You also need lots of speed shear (change of wind speeds with height) and directional shear (change in wind direction with height). You don’t want wind speeds to be too strong though as this can actually kill off tornadoes b/c the updraft gets tilted too
