More intense daily precipitation in CORDEX-SEA regional climate models than their forcing global climate models over Southeast Asia

Abstract

The ability of regional climate models (RCMs) to accurately simulate the current climate is increasingly important for impact assessments over Southeast Asia (SEA), identified as one of the world's most vulnerable regions to climate change. In this study, we evaluate the performance of a set of regional high-resolution simulations from the Coordinated Regional Climate Downscaling Experiment-SEA (CORDEX-SEA) in simulating rainfall over the region. Simulations of the 1982–2005 seasonal mean climatology of daily precipitation and precipitation distribution over land are compared to observations from different sources (i.e., in situ-based and satellite-based). We also evaluate to what extent the..
