冬季大气污染与天气条件分析及预报

Analysis and forecast of atmospheric pollution with weather condition in winter

本文用能见度的好坏来表征大气污染程度,通过对能见度与风速,风向的相关分析,从500hPa大气环流和地面气压场相结合入手,预报风速、风向及能见度,从而得到夜间和白天大气污染预报。

The paper uses good or bad of visibility to indicate degree of atmospheric pollution.Through analyseing interrelation a mong visibility and wind speed /dire ction,and comprehensively thinking atmospheric circulation o n 500hPa and pressure field on the sur face,it predicts wind speed /direction and visibility,th en gets atmospheric pollution forecast at daytime and nighttime.
