1901-2007年澳门地面气温变化的分析

 利用澳门的气温观测资料, 分析了澳门1901-2007年地面气温变化的基本特征。结果表明：近107 a的升温率为0.066℃/10a, 明显低于全球平均升温率。季节平均气温的年代际变化有明显的季节差异，最大的增暖发生在春季和冬季，夏季的增暖最小；冬、夏季的变化分别有明显的时间尺度约为60 a和30 a的振动。年平均最高气温的升温率仅为最低气温的一半左右。最高气温的年代际变化呈缓慢的气候波动现象，20世纪80年代中期以后的升幅与历史上的增暖大致相当；最低气温近20多年来的增暖趋势可能是其长期（变暖）趋势的延续。年平均日较差整体来说是趋于减少的，但近30 a却趋于增加。

Analysis of Surface Air Temperature Change in Macau During 1901-2007

The climate change was studied on the basis of daily series of temperature observations over the period 1901-2007 in Macau. The result shows that annual mean surface air temperature in Macau as a whole rose by about 0.71℃, with a warming rate of about 0.066℃/10a. The warming is far lower than the average values of the world. The most evident warming occurred in spring and winter. The interdecadal variations of the seasonal mean temperature in summer and winter appeared as a series of waves with a time scale of about 30 years and 60 years, respectively. Minimum temperature increased about twice as fast as maximum temperature, resulting in a broad decline in the diurnal temperature range. The interdecadal variations of maximum temperature are obviously different from those of minimum temperature. It appears that the recent trends in maximum temperature may be part of slow climate fluctuations, whereas the recent trends in minimum temperature are consistent with long-term trends.
