摘  要:
利用多种常规观测资料对滨州市2011年12月3~7日和2012年3月16~17日2次大雾天气过程进行分析,探讨了大雾天气产生的环流形势及其形成的大气层结特征、垂直运动特征、温湿条件等。结果表明,稳定的环流形势及地面较弱的气压场是大雾形成的有利天气形势;风力小,空气湿度大,有利于雾的形成;低层西南气流是大雾形成并维持的主要水汽来源;近地层形成逆温层,使大气层结处于稳定状态,是大雾形成和维持的重要条件;低层垂直运动较弱,对水汽的扩散不利,有利于雾的维持。

摘  要:
A variety of routine observations was used to analyze the process of the two heavy fog of Binzhou City on December 3 to 7,2011 and March 16 to 17,2012,and discuss the circulation situation of the fog formation,the characteristics of its atmospheric stratification,vertical motion characteristics,including temperature and humidity conditions.The results showed that stable circulation situation and weak ground pressure field is favorable weather situation for fog formation;Small wind and higher air humidity is conducive to the formation of fog;The lowlevel southwesterly flow is the main source of water vapor for fog to form and maintain;Inversion layer near the ground makes atmospheric stratification in a stable state.It is an important condition for fog formation and maintenance;The weaker vertical movement near the ground against the diffusion of water vapor.However,it is conducive to the maintenance of fog.
