Evolution of a particle created by seeding at 3350 meters m.s.I. as
it falls to the surface. Solid line represents the change in particle
diameter with altitude, and line segments represent the change in
ice particle diameter with altitude (a), time (b), and temperature (c) 120
Plumes of nuclei originating from each ground generator
on January 27, 1989, at 0000 CUT. The + indicates the
nucleation point, and the * indicates fallout point on

the ground . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. 122

Plume of nuclei showing the vertical dispersion (a) of AgI
crystals from a ground generator and the trajectory of
a particle created by seeding on January 12, 1988, at 0000 CUT.
Evolution of particle size (b) created by ground seeding
from nucleation to evaporation on January 12, 1988, at 0000 CUT. . .. 123
Model domain (heavy line rectangle) in Morocco (figure

Model topography obtained using a 10-kilometer grid interval.
Elevation contours are in feet (from EI Majdoub, 1989) ........... 131

Scatter plot of model-computed versus observed monthly
precipitation for Bin EI Ouidane (El. = 2657 ft;
correlation = 0.83) (from EI Majdoub, 1989) ................... 132
Scatter plot of model-computed versus observed daily
precipitation for Bin EI Ouidane (correlation = 0.73)

Map showing terrain, radar location, and target and control
areas used in the radar analyses. The elevation contours
are shaded in SOD-meter intervals.. . . . . . . . . . . . . . . . . . . . . . . . . . .. 139
Terrain cross sections along the 530, 1520, 2170, and 3200
radials from the radar site at Khouribga. The curvature
of the base line and lines of constant elevation represent
the effective curvature of the earth (assuming standard
refraction of the radar beam). Solid lines radiating out
from the center illustrate the field of view along the
00, 10, 20, and 30 elevation angles. . . . . . . . . . . . . . . . . . . . . . . . . . . .. 140
