FOR WIND SHEAR TO INFLUENCE A STORM TO PRODUCE A TORNADO, THE POSITION OF THE UPDRAFT NEEDS TO SHIFT TO VERTICAL RATHER THAN HORIZONTAL. THE DIFFERENCE IN WIND DIRECTION AT THE SURFACE VS ALOFT ...

Tornadoes typically spin counterclockwise in the northern hemisphere. However, a small percentage do spin in the opposite direction. Here's why.

Lou White, a Facebook follower of mine in Kentucky, asked me about tornado debris in his home county. That county is Leslie ...

This often creates a horizontal spin in the air. The leading research on tornado formation says that the horizontal vortex of air turns vertical inside a severe thunderstorm with updrafts and ...

Tornado Alley is shifting eastward because of a combination of weather phenomenon, says meteorology professor who is tracking ...

or outflow boundaries where air masses converge and create horizontal rotation. This rotation can be tilted into the vertical by an updraft, leading to the formation of a tornado. Reminder ...

The conditions can cause spinning air currents inside the cloud, which start out horizontal and then can become vertical, creating a tornado in just a matter of seconds. Currently, the National ...

It’s been a year since the Tallahassee tornadoes downed trees and damaged structures.Residents of the hard hit Indianhead ...

It begins horizontal, but can easily can become vertical and if it touches the ground, it becomes a tornado. The winds in a tornado can be the fastest on Earth reaching speeds in excess of 300 ...

instead of only horizontal, giving a closer look at storms that allow for easier confirmation of a tornado, experts say. “The dual polarization allows us to actually see debris being lofted into ...
