哀牢山气温时空分布特征：最热月为６月，最冷月为１２月（东坡）或双月（西坡）；日平均最低气温在０７—０８时出现，日平均最高气温在１５—１７时出现；平均气温的垂直分布一般是东坡高西坡低．
The characteristics of air temperature on Ailao Mountains are as following: 1. In general,the hottest month of the mountain occurred in June. The coldest month was earlier in the east (December)than in the west (January). 2. Occurring time of daily minimum temperature,except which was 1h later in only January, was basically consistent with the sunrise time. Occurring time of daily maximum temperature was earlier in January to April (occurred at 16 o' clock-17o'clock) than in July to October (occurred at 15 o'clock). In October to January of next year,the occurring time was 1-2h later at the middle and higher altitudes (>1 400m )than at the lower altitude. 3. Monthly t6mperature increment was generally greater in the west than in the east, while monthly temperature decrement was less in the east than in the west, because the former is the windward slope of cold air. The temperature increment or decrement was lightly reduced with increasing altitude. Maximum monthly temperature increment ranged from 2. 0'C to 3. 0℃ and it was 1 month later in the east (March to April) than in the west (February to March). Maximum monthly temperature decrement was 3. 0℃ to 4. 0℃ and the maximum of both slopes occurred in October to November. October was turning period of temperature.4. Generally,air temperature at same altitude was higher in the east slope than in the west one. When there was a strong inversion temperature only in winter, air temperature at altitude above the warm zone (1 800m) was 0. 1-0.2℃ higher in the west than in the east.
