Module Goal

The hodograph is a graphical tool that helps forecasters evaluate vertical wind shear. In a convective envorinment, an understanding of the vertical wind shear is tremendously important for anticipating convective storm type, the likelihood of supercell storms, where new storms may form, and even storm and storm system motion. After completing this module you should understand how hodographs are constructed and how they can help you estimate the total shear, mean shear, and mean wind. To learn how shear impacts the development of convective storms, see the companion module Principles of Convection III: Shear and Convective Storms.
