Abstract
This study evaluates the performance of RegCM3 (Regional Climate Model Version 3) in simulating the East Asian rainfall, with emphasis on the diurnal variations of rainfall over Southeast China during the 1998–2002 summer (June–August) seasons. The evaluation focuses on the sensitivity of the choice of cumulus parameterizations and model domain. With the right setup, the spatial and temporal evolution of diurnal rainfall over Southeast China, which has not been well simulated by past studies, can be accurately simulated by RegCM3. Results show that the Emanuel cumulus scheme has a more realistic simulation of summer mean rainfall in East Asia, while the GFC (Grell scheme with the Frisch-Chappell convective closure assumption) scheme is better in simulating the diurnal variations of rainfall over Southeast China. The better performance of these two schemes [relative to the other two schemes in RegCM3: the Kuo scheme and the GAS (Grell scheme with the Arakawa–Schubert closure assumption) scheme] can be attributed to the reasonable reproduction of the major formation mechanism of rainfall—the moisture flux convergence—over Southeast China. Furthermore, when the simulation domain covers the entire Tibetan Plateau, the diurnal variations of rainfall over Southeast China are found to exhibit a noticeable improvement without changes in the physics schemes.

Notes
Note that because increases of errors in simulating \( {\bar{\text{P}}} \) are also evident when we use NCEP2 reanalysis as the lateral boundary condition (see also footnote 1) to drive the two domains (not shown), the difference in lateral boundary condition errors is likely not one of the causes for the increases of errors in simulating \( {\bar{\text{P}}} \).
The observed and simulated percentage (%) of Var(ΔP)SEC explained by its related S1(P)SEC and S2(P)SEC is listed in row 7 and row 12 of Table 4 respectively.
\( ( - \nabla \cdot {\mathbf{\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\rightharpoonup}$}} {Q} }}) = - \nabla \cdot \left( {\int_{{{\text{P}}0}}^{{300{\text{hPa}}}} {{\mathbf{\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\rightharpoonup}$}} {V} }}{\text{q}}\,{\text{dp}}} } \right) \), where V denotes the horizontal wind, q is the specific humidity, and p is the pressure level.
