Description information

0-6km vertical shear：The surface to 6 km above ground level change in wind. Thunderstorms tend to become more organized and persistent as vertical shear increases, while supercells are commonly associated with vertical shear values of 20-35 m/s and greater through this depth.

Calculation formula:

Where a234.png   is the wind of 6 km above ground level and a345.png is the surface wind.
