Fig. 10: Examples of measured drop-size distri-
butions in rain. Indicated for eaph curve are
the duration of the observation, the total
number of drops counted, and the average rain-
fall rate. Distributions 1 and 2 were recorded
during nearly constant rain; distribution 3
was recorded during a thunderstorm. (From Joss
et aI., 1968.)

a drizzle, widespread rain and thunderstorm situation. The distributions 9re
summed over the entire precipitation episode. (From Joss and Waldvogel, 1$70.)
