why do tornadoes occur in tornado alley

What is "Tornado Alley"? The land in the central United States is the best breeding ground for the storms which produce tornadoes. The land in the Great Plains is relatively flat, which allows cold dry polar air from Canada to meet warm moist tropical air from the Gulf of Mexico.


It's along the front between the two airmasses that most tornadoes. Most tornadoes in the United States form in an area called "Tornado Alley".


This area includes parts of Texas, Oklahoma, Kansas, and Nebraska. travel to this area because of the high concentration of tornadoes.


These tornadoes are formed by. Some of the tornadoes in the southern states such as Florida, South Carolina, and Georgia are caused by.
And they are all driven by atmospheric instability and by a phenomenon known as wind shear.


This happens when wind near the ground blows in one direction, but aloft it blows in another direction. This creates shear in the airflow, Karstens explained.


If you produce an updraft within that flow, the updraft will acquire the properties of the air, and the atmosphere begins to spin and rotate.
