| 摘 要： | 双流机场全年近1／3的日子有低见度天气出现，最多的冬季平均日数达到的总数的80％，而且低能见度有明显的季节变化和日变化。低能见度主要由辐射雾造成。二次低能见度天气为其特点，主是由弱冷空气进入暖湿气团所致。

| Abstract: | Low-visibility occurrence at Chengdu Shuangliu Airport covers almost one third of a year. Low-visibility days in winter, the season when low-visibility appears most frequently, occupy an average of 80% of the total days in the season. Low-visibility varies in different seasons and even in one particular day. It is resulted from radiation fog. It is characterized by twice low-visibility weather, brought about by the intrusion of weak cold air into wet warm air mass. |

| Keywords: | Low-visibility twice low-visibility radiation fog active cloud condensation nucled |
