A study of radar echo patches in summer storms.

Plots of areal coverage as a function of height and intensity have been made for 17 radar echo patches all smaller than 1300 nmi.^2, that were recorded on the constant altitude maps of the 3-cm McGill radar. From these plots, vertical profiles of flux and density of precipitation have been obtained. The profiles generally showed maximum values aloft. The maxima were usually observed to descend or remain at one level. Occasions of ascent were less frequent. [...
