Day: Diurnally driven convection
Night: Developing system
CloudSat CPR
Day: Decaying system
Night: Developing system
West Pacific Ocean
Ocean
Taller anvil with mature system
during day, but broader
distribution at night (convective)
CloudSat CPR, TRMM PR
Maritime Continent vs. West Pacific
Subtle difference
overall!
Taller, broader, more
intense over MP
- Diurnal?
- Land vs Ocean?
- Conv/strat?
CloudSat CPR
Maritime Continent vs. West Pacific
Biggest differences during day
More intense, broader over MC
Taller for WP
CloudSat CPR
Taller, strong, broader
over MC at night
