| Abstract: | Xishuangbanna of Yunnan Province is a famous tropical foggy region. A field experiment was carried out from November 23 to 30 of 1997 during which fogs occurred regularly every day. In the paper the characteristics of macrostructure of fog are analyzed and the physical processes of formation and dissipation of fog are studied. The results show that the Xishuangbanna valley fog forms firstly in the lower atmosphere with two-layer structures and then develops suddenly in the vertical direction after reaching the ground. Furthermore, the vegetation effect on the formation and dissipation of fog is discussed specially. |
