| 摘 要： | 2005年2月23-25日和2006年3月6日深圳分别出现了一次大雾天气。从天气学角度对两次大雾过程的形成原因、特点进行对比分析，分析表明：大雾天气需在一定的形势场中出现并维持，近地面层气象要素场的变化会促进大雾的形成、维持和消失，而近地面层风场或温度场的改变除了与其环境、当地气候特征有关外，与大的形势场是分不开的。通过对比，对深圳大雾天气的生消和维持机制有一定了解，对预报本地大雾天气有指示作用，也为其它地区特别是沿海地区雾的预报提供借鉴。

| Abstract: | Heavy fogs occurred in Shenzhen on February 23-25, 2005 and March 6, 2006 respectively. This paper conducts the comparison analysis for the formation reason and the characteristic of two bad fogs processes regarding to the synoptic meteorology. The analysis indicates that the bad fog weather can appear and maintain in a certain situation field, the change of meteorological element field near ground layer can promote the formation, maintenance and vanishing of the fog. The change of wind field or temperature field near ground layer cannot separate with the big situation field except but related to the environment and local climate characteristic. Through the comparison, it makes a certain understanding to the appearance and disappearance and maintenance mechanism of the bad fog weather in Shenzhen, and shows the instruction function to the forecasts of local bad fog weather, and also provides a model of fog forecast for other areas specially the coastal area. |
