1. Pre-Monsoon
Monsoon
TRMM PR data reveal the nature of the convection producing extreme monsoon rains
In the monsoon:
Deep cores shift from Bengal to Pakistan
Wide mesoscale systems develop along the Himalayan foothills
Broad stratiform systems dominate upstream of the mountainous coastlines
Deep Convective Cores
Wide Convective Cores
Broad Stratiform Regions

2. A composite of TRMM PR data in 9 years of hurricanes in the Atlantic basin show that eyewall convection is systematically deeper and more intense than deep convection in the environment of the cyclone
Colors represent probability of occurrence with 20, 50, & 80% contours in black.
