Abstract: The NCAR Community Atmosphere Model (CAM4.0) was used to investigate the climate effects of land use/land cover change (LUCC). Two simulations, one with potential land cover without significant human intervention and the other with current land use, were conducted. Results show that the impacts of LUCC on diurnal temperature range (DTR) are significant. In the mid-latitudes, LUCC leads to a decrease in DTR, which is mainly caused by the reduction in daily maximum temperature. The reduction in DTR in East Asia of the low latitudes is chiefly the result of the decrease in daily maximum temperature, while in the Indian Peninsula, the decrease in DTR is due to an increase in daily minimum temperature. In general, the LUCC significantly controls the DTR change through the changes in vegetation transpiration and canopy evaporation.
Key words: land use/land cover change (LUCC), diurnal temperature range (DTR), climate change
