Study on Predicting Modle of the Nocturnal Radiant Inversion Distribution
夜间贴地逆温分布预测模式研究

The height and strength of temperature inversions play an essential role in determining the dispersion of air pollutants. In this paper a new prediction modle of tem-prature inversion during night-time has been developed by modifying D. Anfossi and A. D. Surridge's methods, and three modified coefficients abount wind speed, aqueous vapour and temprature differences at groun have been given. The vertical temprature profiles obtained from the present modle have been compared with observations and the agreement is found to be better than previous models. The new modle can replace the method for measuring the temprature profile with balloon-borne thermo-sonde in the environment impact assessment.
