The regional climatic effects of land cover change in Guizhou Karst Plateau (GKP) were investigated using the WRF model. The WRF showed high ability to downscale NCEP-DOE Reanalysis-2, especially for the precipitation simulation. After land degradation over GKP, the net radiation and evaporation were reduced mainly within the desertification area, consistent with the reduction in rainfall and the increase in surface temperature there. The southwest monsoon flow from the Bay of Bengal was weakened over the adjacent area to the northeast, influencing the East Asian summer monsoon. Meanwhile,...
