Fig. 3. Three different clockwise curving hodograph shapes and the resulting storm motions. The long, thin arrow on each hodograph represents the mean wind shear vector. The circle positioned along this vector represents the estimated mean wind speed. The heavy arrow extending from the origin indicates the computed mean storm motion. On the right side of the figure, the low-level reflectivity corresponding to the various hodograph shapes are shown. The heavy arrows are the same as the mean storm motions shown on each hodograph.
