Orography Organizes Monsoon Rain

Liu et al. [2005] characterized the large-scale seasonal monsoon system driven by ocean-continent contrast, using QuikSCAT and TRMM observations. The high-resolution spacebased data also reveal that the regional distribution of monsoon rain is governed by orography. The mechanism of the local orographic-induced convection is postulated and simulated in numerical experiments by Xie et al. [2006].
