Abstract:Xishuangbanna is located at the northern edge of the distribution of tropical forest in Southeast Asia, and it has a very high frequency of radiation fog, especially during the dry season (November~April). Radiation fog events in this site are generally associated with low wind speeds and region-wide air mass stagnation resulting from strong nighttime radiative cooling. Intercepted fog water by forest canopy from both the windward edge and leeward edge to the interior of the forest and related microclimatic...
