对几种大气环境预测方法的评估

Appraisal on Several Forecasting Methods of Atmospheric Environment.

本文根据石家庄市的常规气象资料和混合层高度,用不同的计算模式和计算方法对本市特征污染因子SO_4的长期平均浓度进行计算,把计算结果与实测浓度比较并进行误差分析,对每种计算方法进行评价,最后讨论了各种计算方法的特点及在城市大气环境预测中的实用性.

In this paper, the average concentrations of SOa which is typical pollutant in the atmosphere for a longtime, have been calculated with different diffusion nodels and methods acting to routine meterologic data in Sbijia-zhuang City and the height of mixing layer over the city. By comparing calculated values of the concentrations with monitored air concentrations, their errors were analyzed and every kinds of calculating methods were appraised. Finally the characteristics and feasibility of these calculating methods in forecasting atmospheric environment have also been discussed.
