盘锦地区大雾时空分布特征及其发生的气象条件分析

Analysis on Spatial-temporal Characteristics and Meteorological Conditions of Fog Formation in Panjin Area

利用2000—2016年盘锦2个国家站气象资料,统计分析盘锦地区大雾时空分布特征和生、消特点。结果表明,盘锦地区沿海更易发生大雾;具有明显的月、日分布特征,秋季、冬季多发,春季、夏季节则较少;雾大多数发生于4:00—10:00,很少发生于12:00—18:00;大雾发生时湿度较大,低层有逆温,多为较小偏南风。

Based on the meteorological data of two national stations in Panjin area from 2000 to 2016, spatial and temporal distribution of fog were analyzed.The results showed that fog was more likely occured in coastal of Panjin City,and showed a significant monthly and dally distribution characteristics.Fog more likely occured in autumn and winter,less likely occured in the spring and summer.Fog mostly occured from 4：00 to 10：00, rarely occured from 12：00 to 18 ： 00.Fog occured when the humidity was higher, low-level inversion, mostly smaller southerly wind.
