A highly versatile numerical code – the Regional Atmospheric Modeling System (RAMS) was used into the heat island simulation of an inland mega-city – Chongqing and Sichuan Basin, China. The entire horizontal calculation domain 2000 km ×2000 km and the vertical calculation domain was from 50cm under ground to the altitude of 15 000 m. The USGS (U.S. Geological Survey) topography and land use data, the NCEP (National Centers for Environmental Prediction) meteorological data were used as the input data of this simulation. The simulation shows that the temperature of Chongqing's urban area was higher than that of suburb area corresponding to the topographical condition. It was confirmed that RAMS could be applied for the simulation of thermal environment. It was also demonstrated that the local climate in the smaller scale could be expressed by generating two-way interactive nesting grid.
