| 摘 要： | 基于长城站气象观测数据和NCEP再分析资料,分析研究了长城站海雾的发生背景和天气形势。认为长城站海雾的季节性变化是大气环流、地面气压场变化的结果;长城站海雾形成的天气形势基本可分为低压锋前型、鞍型场型和弱气旋过境型3类,其中低压锋前型是长城站海雾形成的主要天气形势。长城站以平流冷却雾为主,也存在其它类型的雾。本文从天气学角度分析了长城站海雾发生的原因,为该地区的海雾预报提供了依据。

| Abstract: | Based on the observed data of Great Wall Station and NCEP data from 1985 to 2006, analyzation was made by climatological statistics and synoptic analysis. It is showed that the seasonal variation of the fog was controlled by atmospheric circulation and pressure field. Three typical synoptic patterns of the fog are found, they are the Front-of-A-Depression type, the Saddle-Shaped-Field type and the Passing-Weak-Cyclone type. The Front-of-A-Depression type is the most important synoptic situation. Mostly adve... |
