| 摘 要： | The multiple time scale climate changes are studied and calculated with statistical analysis and wavelet transformation on the basis of daily series of observed data over the period 1901-2007 in Macau.The result shows that statistically significant oscillations with 2 to 5 years of period generally exist in the series of climate variables(e.g.annual mean surface air temperature and precipitation as well as evaporation etc.),but with obvious locality in time domain.The variation of annual mean surface air temperature has a quasi 60-year period.The phases of the 60-year variation approximately and consistently match that of Atlantic Multidecadal Oscillation(AMO).The oscillations of seasonal mean surface air temperature in summer and winter have the periods of quasi 30-year and quasi 60-year,respectively.These two periods of oscillations have statistically significant correlation with Pacific decadal oscillation(PDO) and AMO,individually.The multidecadal variations of the precipitation of the annually first flood period and annual evaporation are dominated by periods of quasi 30-year and quasi 50-year,respectively. |

| Abstract: | The multiple time scale climate changes are studied and calculated with statistical analysis and wavelet transformation on the basis of daily series of observed data over the period 1901-2007 in Macau. The result shows that statistically significant oscillations with 2 to 5 years of period generally exist in the series of climate variables (e.g. annual mean surface air temperature and precipitation as well as evaporation etc.), but with obvious locality in time domain. The variation of annual mean surface air temperature has a quasi 60-year period. The phases of the 60-year variation approximately and consistently match that of Atlantic Multidecadal Oscillation (AMO). The oscillations of seasonal mean surface air temperature in summer and winter have the periods of quasi 30-year and quasi 60-year, respectively. These two periods of oscillations have statistically significant correlation with Pacific decadal oscillation (PDO) and AMO, individually. The multidecadal variations of the precipitation of the annually first flood period and annual evaporation are dominated by periods of quasi 30-year and quasi 50-year, respectively. |
