1999年1月至2002年12月期间，在中国西南部西双版纳的热带季节性雨林中测量了雾滴和相关的小气候因子。研究期间，年平均雾滴量为 89.4 +/- 13.5 毫米（平均值 +/- 1SD）。雾滴估计占年降雨量的 5%，其中 86% 的雾滴发生在旱季（11 月至 4 月）。年雾滴水量与年降雨量呈负相关。雾滴的月变化也与月降雨量呈负相关。在发生雾滴的所有日子里，平均每日雾滴为 0.38 +/- 10.2 7 mm d(-1)。每日雾滴与最低气温呈负相关，与树冠上方平均风速呈正相关。结果表明，雾滴是旱季期间该季节性雨林重要的额外水输入。
Fog drip and related microclimatic factors were measured between January 1999 and December 2002 at a tropical seasonal rain forest in Xishuangbanna, South-West China. During the study period, the annual average fog drip was 89.4 +/- 13.5 mm (mean +/- 1SD). Fog drip contributes an estimated 5'% of the annual rainfall, with 86% of the fog drip occurring in the dry season (November-April). Annual fog drip was negatively correlated with annual rainfall. Monthly variation in fog drip was also negatively correlated with monthly rainfall. Average daily fog drip was 0.38 +/- 10.2 7 mm d(-1) for all days on which fog drip occurred. Daily fog drip was negatively correlated with minimum air temperature and positively correlated with mean above-canopy wind speed. The results indicate that fog drip is an important additional input of water to this seasonal rain forest during the dry season.
