24Alteration of Precipitation Processes
TRMMs Precipitation Radar confirms that clouds
in areas 1, 2, and 3 all have sufficient water
for precipitation, however there is only
precipitation occurring in areas 1 and 3. The
yellow coloring of area 2 depicts pollution
tracks, as detected by TRMMs Visible Infrared
Radiometer (VIRS) instrument.
Thus the integrated picture delivered by TRMM
suggests a suppression of rain and snow by smoke
and air pollution due to the shifting of droplet
size.
Prof. Daniel Rosenfeld
25How can weather forecast duration and reliability
be improved by new space-based observations, data
assimilation, and modeling?
- Assimilation of TRMM precipitation data in global
models - Improves climate analysis

Ongoing model improvements Enhancements in
computing resources
- Reservoirs and tropical rainfall well quantified
- Difficulty balancing the water budget on any
scale - Inability to observe and predict precipitation
globally
