Figure 87. Westerly water vapor flux from rawinsondes, water release
rate from C-band radar and rawinsondes, radiometer super-
cooled liquid water depth, lidar linear depolarization
ratio, and Rosemount probe supercooled liquid water content
as a function of time and, in some cases, other variables.

Figure 88. Same as Fig. 87 but for the period from 0400 MST to near the
end of the STORM (-1700-2000 MST) on 9 February.

radiometer in the zenith direction from 2200 MST to 0320 MST
on 8-9 February 1985.

depolarization ratio, precipitation particle habit, average
precipitation particle mass, precipitation particle number
flux, and precipitation rate as a function of time and, in
some cases, other variables.

Figure 93. Same as Fig. 92 but for the period from 0400 MST to near the 285
end of the STORM (-1700-1900 MST) on 9 February.

Figure 94. Vertically-integrated westerly water vapor flux, normalized
vertically-integrated westerly supercooled liquid water
flux, and horizontally-integrated precipitation mass flux
all plotted as a function of time on 8-9 February. See text
for details.

Figure 95. Water release rate integrated vertically through various
temperature levels of the clouds and integrated vertically
from the surface to cloud top all as a function of time on
8-9 February.

Figure 96. Mean supercooled liquid water amount measured by the radio-
meter in the western sector from l80 degrees to 360 degrees
of azimuth '(solid line) or in the zenith direction overhead
(dashed line) as a function of time on 8-9 February.

site and at gages P3-P7 on average as a function of time on
8-9 February.
