摘要
云南省西双版纳地区是世界著名的热带多雾区。 1997年 11月 2 3—30日 ,实施了一项雾的外场考察计划。这期间雾过程每天都很有规律地出现。本文分析了雾的宏观结构特征 ,研究了雾生消的物理过程。结果发现 ,西双版纳谷地雾首先形成于低空 ,并且具有双层结构 ,及地后则在垂直方向突然增长 ,使雾层爆发性增厚。文中对植被在雾生消过程中的作用 。
Xishuangbanna of Yunnan province is a famous tropical foggy region.A field experiment was carried out from November 23 to 30 of 1997 when a fog occurred regularly every day.In this paper the characteristics of macrostructure of fog are analyzed and the physical process of formation and dissipation of fog is studied.The results show that the Xishuangbanna valley fog forms firstly in the low layer atmosphere and also has two layer structures.The fog increases suddenly in the vertical direction when it reaches the ground,which makes the fog layer develop explosively.Furthermore the vegetation effect on the formation and dissipation of fog is discussed specially.
