| 摘 要： | 使用小波分析方法检测了副高脊线位置在１９７９年发生的突变，检验结果与Ｍ－Ｋ方法检验结果一致，进一步分析指出，东亚乃至全球大气环流在１９７９年也发生了突变，相应地中国降水分布也从中间旱，南北涝转变成中间涝，南北旱的分布，旱涝分布型同时发生突变。

| Abstract: | The catastrophe of subtropical high ridge position in 1979 is examed with the aid of wavelet analysis test,the result is quite the same with that by Mann Kendall test; Further analyses show that the catastrophe of East Asia and the Global atmosphere general circulations also takes place in 1979, meanwhile China rain pattern changes from the central drought two side flood to the central flood two side drought. |

| Keywords: | atmospheric general circulation dry and wet patterns wavelet analysis climate sudden change |
