Convective Thunderstorms; Unaltered Tilt - Honeywell PRIMUS 660 Pilot's Manual

D
Convective thunderstorms become much less reflective above the
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.
D
If the tilt angle shown in figure 5–11 is not altered, the thunderstorm
appears to weaken as the aircraft approaches it.
