CALCULATION AND DISCUSSION ON CORRECTING MODEL OF THE POTENTIAL TEMPERATURE ABOVE COMPLEX TERRAIN BASED ON NOAA/AVHRR AND DEM

摘要

This paper analyzed factors which affects the mountain temperature. Taking Chongqing in China as an example, the black-body temperature (TBB) retrieved from NOAA/AVHRR data was converted into the potential temperature, referring the concept of the potential temperature and confirming a height base. These results show that characteristic of the potential temperature field distinctly changes than before calculation. Then, this paper found the revised coefficient for γ (the lapse rate of temperature) through analysis about terrain factors, which can afford idea and method to protect the mountain environment and make full use of climate resources.
