Abstract

The advantages of three or more radars is illustrated in terms of extended areal coverage, error variance reduction and mitigation of poor sampling effects of divergence fields near the ground. Errors in the horizontal and vertical particle motion fields are illustrated for a three-, four- and five-radar network, and the importance of experimental design is illustrated. A variationally formulated multiple-Doppler radar analysis, which includes data from a surface network, and an illustrative analysis of storm data are presented.
