| 本文通过对夜间逆温分布试验数据的研究,提出了一个新的晴朗夜间贴地逆温分布预测模式,以及风速、相对湿度、地面温差三项修正系数的确定方法,模式预测结果与实测值比较,吻合程度优于其他模式,新的预测方法可以满足大气环境评价和空气污染潜势预报的要求,能够替代夜间低空探空试验。 |
| 英文摘要 |
| 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. |
