This study examines cloud radiative forcing (CRF) in the Asian monsoon region (0°-50°N 60°-150°E) simulated by Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) AMIP models. During boreal winter, no model realistically reproduces the larger long-wave cloud radiative forcing (LWCF) over the Tibet Plateau (TP) and only a couple of models reasonably capture the larger short-wave CRF (SWCF) to the east of the TP. During boreal summer, there are larger biases for central location an...

1. Introduction Clouds are important modulators of the earth en- ergy budget. Macrophysical and microphysical cloud properties and their distribution have profound im- pacts on radiative process, precipitation, and the gen- eral circulation (Ramanathan et
