摘要
利用泰安交通气象观测站和单能见度仪资料,结合常规地面观测资料和GFS分析资料,对泰安2011~2014年发生的多次雨雾特征进行综合对比分析,并且针对2011年夏季的一次雨雾过程从天气形势、生消原因、能见度与多种气象要素的相关性进行了深入研究。结果表明:(1)2011~2014年,泰安雨雾天气主要发生在夏季和秋季的夜间到清晨,持续时间在3h以下,最低能见度基本在500 m以上。(2)对110622雨雾过程而言,偏南气流在泰山南麓辐合抬升是降雨形成的重要条件,降雨的蒸发是雨雾形成的根本原因,且降雨量较大,弱降水是雨雾维持的重要条件。(3)110622雨雾发生期间,相对湿度与能见度反相关性较强,但不随能见度波动而波动;风速很小,基本不超过2m/s;逆温层较低,辐射降温不明显,逆温较弱。
The synoptic situation,the cause of generation and disappearance,as well as the relativity between visibility and several meteorological elements are deeply analyzed for the rain fog of Tai'an in the summer of 2011,by using the data colleceted by the traffic meteorological observation stations, the surface meteorological observation stations and GFS from 2011-2014. As a result, the following conclusionss are reported: 1) In Tai'an, the rain fogs mostly occurred in the night and early morning periods of the summer and autumn seasons during 2011-2014. All fogs had less than 3 hours duration, and the lowest visibility is generally above 500 m. 2)To the rain fogs(2011,06,22), the convergence and lifting of southerly airstream on the south side of Mount Tai is the important contributor of the rainfall, and the evaporation of the rainfall is the primary cause of the rain fog with the much more rainfall. The weaker precipitation supported the rain fog maintaining. 3) The inverse correlation of humidity and visibility is stronger,but the humidity does not fluctuate with the visibility. The wind speed is very low with less than 2m/s. we also got these facts as the lower inversion layer,weaker temperature inversion and the radiation cooling effect.
