The bases of the radar echo descend as particles grow and fall and are illustrated by the dashed lines in the top panel for two different wind speeds. Vertical depth of echoes as a function of downwind distance depends, in part, on wind speed. Seeding material is released either as BIP or EJ flares.

(top) A vertical cross section along the flight track of the UWKA and (bottom) a plan view. Yellow dots show locations of ground-based radars, the red line represents a typical flight track for the seeding aircraft under westerly winds (left to right across the figure), and the blue line is the corresponding flight track for the UWKA. The yellow–orange–red colors indicate locations and relative magnitude of radar reflectivity echoes.
