This advanced measurement, part of dual-polarization radar technology, detects how similarly shaped objects are within a ...

I had never seen anything like it before." [See video of the roll cloud ] The cloud was rolling around like a "sideways tornado," Fitzhugh said. In fact, roll clouds form where sinking cold air ...

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 ...

An Ohio man captured a video of rare horizontal tornadoes getting sucked into a larger tornado near his house in Wapakoneta. Chad Steinke said the wind tipped over a fuel tank on his property and ...

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 ...

Wind shear creates the spinning vortex of air needed for tornado formation. That spinning vortex initially lays horizontal, or parallel to the ground. If a strong enough storm can come along ...

The city also shared images of the tornado's aftermath. One showed a car pileup in a parking lot while another two showed large trees and a light post turned horizontal on the ground — in one ...

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 ...
