摘要: AbstractA nonhydrostatic, regional climate limited-area model (LAM) was used to analyze lateral boundary condition (LBC) errors and their influence on the uncertainties of models. Simulations using fully compressible nonhydrostatic LAM (D-NICAM) were compared against corresponding global quasi-uniform-grid Nonhydrostatic Icosahedral Atmospheric Model (NICAM) a stretched-grid counterpart (S-NICAM). By this approach sharing same dynamical core physical schemes, possible causes bias LBC are isolated. The simulations performed for 395-day period from March 2011 through 2012 with horizontal grid intervals 14, 28, 56 km in region interest. resulting temporal mean statistics temperatures at 500 hPa generally well correlated between simulations, indicating that had minor impact large-scale flows. However, time-varying surface precipitation showed the...
