About the Possibilities of Using an Air Mass Transformation Model in Taiyuan, Shanxi Province, China

摘要

The AMT-model is tested for trajectories arriving in Taiyuan to study the possibilities of using it in Taiyuan, People's Republic of China. The sensitivity of the model for the different processes was studied. Some parameters of the model were modified for the purpose of forecasting in specific mountainous terrain and dry climate conditions. Results of examples which the authors have worked out for Taiyuan circumstances for the periods of July (summer) 1985 and January (winter) 1986, show that the 12 hour runs of the AMT-model are able to reproduce (on historical data) the sounding of Taiyuan. The AMT-model contribute fruitfully to short-range weather forecasts (12-36 hours ahead) during periods of severe air pollution and when cold waves occur.
