Why Do Tornadoes Turn Counter Clockwise?

Usually, tornadoes in the U.S. rotate counterclockwise. Coriolis force
Coriolis force
The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame (more precisely, to the component of its velocity that is perpendicular to the axis of rotation).
, imparted due to the Earth's rotation, causes air around low centers to circulate counterclockwise in the northern hemisphere. ... Thus, tornadoes, being an outgrowth of these rotating updrafts, tend to spin counterclockwise.
Why do tornadoes go counterclockwise?
"Tornadoes usually rotate in the same direction as the thunderstorm they're associated with." Therefore, if the warm winds blowing north from the equator meet cool upper-level winds out of the west, the tornado will rotate counterclockwise.
Do Tornadoes always rotate counter clockwise?
A tornado -- in the Northern Hemisphere -- usually spins counterclockwise but on rare occasions it can twist clockwise and is called an anticyclonic tornado.
