Potential of representing the diurnal cycle of local-scale precipitation in northeastern Thailand using 5-km and 2-km grid regional climate models

The diurnal cycle of precipitation over northeast Thailand during the Southeast Asian summer monsoon season was examined using non-hydrostatic (5-km grid) and convection-permitting (2-km regional climate models. results indicate that these fine grid models exhibit a better performance in terms representing due to realistic orographic representation. successfully simulated local circulation corresponding intensification were consistent with satellite-based observed precipitation. model simulation indicated convergence area mountain on south Khorat Plateau occurred afternoon association occurrence migrated northward contributed peak plateau nighttime. A bias amount 5-km partially removed through 2-km model.
