| 摘 要： | 利用1958—2007年沈大高速公路沿线6站雾日资料对沈大高速公路雾的气候特征及气象要素进行分析。结果表明：沿海地区雾日偏多，且总体呈上升趋势，内陆地区雾日偏少，且呈下降趋势。内陆地区雾多出现在秋冬季，沿海地区多出现在夏季。雾多在凌晨至日出前后时段生成，日出后逐渐消散，持续时间多为1—3 h。相对湿度、气温、风速和风向对雾的预报有较好指示意义：当相对湿度在90%—100%时，春季气温为-5—15 ℃、夏季为16—24 ℃、秋季为-3~19℃、内陆冬季为-20~2 ℃，沿海冬季为-7~4 ℃范围内，内陆风速为0—3 m•s-1，沿海风速为0—6 m•s-1，且沿海地区为偏南风时，雾易发生。

| Abstract: | Based on the daily fog data at six meteorological stations from 1958 to 2007 along the Shenyang-Dalian highway,the climatic characteristics of fog and its relationship with meteorological elements were analyzed.The results indicate that fog days in the coastal areas are more than in inland areas.It is increasing in the inland areas and descending in the coastal areas.Fog day appears mostly in autumn and winter in the inland areas,while it is in summer in the coastal areas.Fog usually forms at sunrise and di... |
