Figure 1-11. Decay function of the freshwater volume in the upper ocean due to rain f v for
two critical droplet radii: (a) c
r = 0.75 mm and (b) c
r = 0.4 mm. The rainrate P is given below
each curve.
Figure 1-11 shows dependence (1.79) as a function of depth for a
number of rainrates and for two critical radii, c
r = 0.75 mm and c
r = 0.4 mm.
The ratio between penetration depth and drop radius is taken as
