Radar Tutorial
Chapter 1, Page 6: V-Notch Echo
The "V" echo is common wherever supercells may develop. Supercells are different from other isolated thunderstorm cells
in that they rotate with what is called a mesocyclone. This is a classic radar signature of a supercell. These cells
tend to be isolated from other cells, with a clear access to inflow winds often from the southeast. Supercells can last
for many hours. They are huge with large anvils and often an overshooting top. Severe straight line winds are possible at
the gust front with possible shelf or roll clouds. There may be visible signs of rotation in the cell, such as a smooth
rounded appearance or layers of smooth rings or bands on or around the main tower of the thunderstorm. There will likely
be a rain-free base area where inflow converges at the rear of the storm. That is where the tornado could develop.
