Mean radial velocity is a measure of the radial component of the wind either toward or away from the radar.
Spectrum width is a measure of the variation of the velocity within the sampling area.
Level III graphic products are available as color hard copy, gray scale hard copy or acetate overlay copies. A brief description and possible uses of these products are included here. This product is used to detect precipitation, evaluate storm structure, locate boundaries and determine hail potential. A measure of velocity dispersion within the radar sample volume. The primary use of this product is to estimate turbulence associated with mesocyclones and boundaries.
