Abstract

The diurnal cycle in the North American Monsoon System (NAMS) precipitation was analyzed with coupled MM5-SSiB simulation. Statistically signicant diurnal cycle in precipitation was found. Composite analysis showed that heavy rainfall,essentially convective, dominates in afternoons. Time evolution of several parameters was investigated to find the mechanisms responsible for the generation of deep convection and precipitation. It was found that both low-level convergence and convective available potential energy (CAPE) contribute, while the former is critical for precipitation rate to get above 0.6 mm/hr.
