Convective Thunderstorms; Unaltered Tilt - Honeywell Primus 880 Pilot's Manual

PRIMUSr 880 Digital Weather Radar System
Convective thunderstorms become much less reflective above the
D
freezing level. This reflectivity decreases gradually over the first
5000 to 10,000 feet above the freezing level, as shown in figure
5- 10.
The aircraft in figure 5- 10 has a clear radar indication of the
thunderstorm, probably with a shadow in the ground returns behind
it.
If the tilt angle shown in figure 5- 11 is not altered, the thunderstorm
D
appears to weaken as the aircraft approaches it.
