| 摘 要： | 应用梧州地区5个站点1954～2011年逐月降水和平均气温资料,采用趋势分析、小波分析法,分析了近58年梧州地区降水和气温的变化趋势、变化周期性等气候特征。结果表明,近58年梧州地区年降水量、冬季降水量总体呈增加趋势,年降水量存在25年左右、10年左右的震荡周期,季降水量存在一个10年左右的振荡周期最为明显;年平均气温存在一个9～11年的振荡周期;近58年梧州全年、夏季、秋季、冬季平均气温总的趋势均表现为升高趋势,但升高的幅度不同,梧州全年平均气温上升幅度为0.152℃/10a,气候变暖表现明显;梧州58年来出现夏季严重多雨事件8次,严重少雨事件7次;出现秋季严重多雨事件3次,严重少雨事件2次。

| Abstract: | The records of 5 stations' monthly average precipitation and air temperature during 1954-2011 in Wuzhou were employed.Trend analysis and Wavelet analysis were adopted to study changes of precipitations and air temperature,cyclicity of variations and other climate features in Wuzhou nearly 58a.The results showed that: annual precipitation and winter precipitation grew gradually;air temperature increased wavily,and both changes of annual air temperature and seasonal air temperature were different;variations of precipitations and air temperature were periodic;some summer and autumn precipitations were beyond the normal range much;the phases of precipitations and air temperature in summer and autumn was opposite. |
