| Abstract: | Taiyuan lies in the intermontane basin,the largest basin of the Shanxi province.The horizontal distribution and vertical change of wind will greatly influence the horizontal transmission and vertical spread of the pollutants.Temperature distribution is closely related to the flow field in the basin.Taiyuan is a warm temperature region as well as a high pollution region.Under the circumstances of northerly wind,the warm temperature ridge area has high concentration of pollutants.During winter,3000 meters below,temperature inversion exists every day in the basin with more layers,and it lasts for long time with high intensity,which is one of the major factors for serious pollution of the basin. |
