| 摘 要： | 通过对1994-2006年13a伊宁地区气象资料的分析，对伊宁地区大雾的气候学、天气学特征进行了统计；阐述了辐射雾、平流雾两种主要类型的雾的特点；同时，从天气学角度出发，对辐射雾的气象要素特征和平流雾形成的高低空环流形势进行了总结描述；结果表明：伊宁地区为雾多发地区，雾的年、季、月、日变化特征明显，影响飞行的辐射雾与平流雾出现概率相当，总结出了产生雾的几种典型天气形势，为预报员及时准确预报大雾提供参考，同时指出地形对雾的出现及范围有一定的影响。

| Abstract: | By using the data in Yining of Xinjiang from 1994 to 2006, this paper analyzed the statistic characteristics of climatology and synoptic for heavy fog and explicated the features of radiation fog and advection fog as two major types, and from the point of view of synoptic summarized the characteristics of meteorological element forming radiation fog and the circulation situation at upper air and lower level forming advection fog. The results showed that Yining occur fog frequently, its variation features of annual, seasonal, monthly and daily to be obvious and their appeared probability to be almost same for radiation fog and advection fog affecting flight. So several typical synoptic situation of fog are summing-up. It is valuable for forecaster to predict heavy fog timely and accurately. In addition, the landform impact the fog emergence and their area sizes are pointed out. |
