Research Abstract

Diurnal cycle of precipitation over tropics is investigated using a global cloud resolving model (NICAM). The NICAM well captured phase and amplitude of the diurnal cycle as it was observed by TRMM satellite. The simulation further provides other findings, such as resolution dependency of the diurnal cycle and relationship to the mesoscale circulations.
