Abstract: 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.

Key words: surface air temperature change, climate warming, maximum temperature, minimum temperature, Macau
