Abstract: Abstract The biogeophysical impacts of land surface on regional climate have been investigated for the Vu Gia-Thu Bon basin in Central Vietnam using the regional climate model (RCM) Weather Research and Forecasting (WRF) Model. The replacement of land surface due to an updated land-use/land cover data leads to change the biogeophysical properties of land surface, thereby altering the regional climate. Results show that generally surface air temperatures increase by about 0.5 ∘C over the basin. Remarkable increases in surface air temperatures are about 2 ∘C appearing in cities. Annual precipitation decreases by about 800 mm over the Western basin and increases by about 1500 mm over the Southern basin. In general, if roughness length decreases (increases), horizontal wind speed and average maximum Convective Available Potential Energy (CAPE) increase (decrease) by about 1 ms−1 and 20 JKg−1.
