In the monsoon:
Wide
•Deep cores shift
from Bengal to Convective
Cores
Pakistan
•Wide mesoscale

Broad
Stratiform
•Broad stratiform Regions
systems dominate
upstream of the
mountainous
coastlines
Houze et al. 2007; Romatschke et al. 2010; Romatschke & Houze 2010
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.
