| 摘要: |
| 对中国47站1933、1—1987、12月平均气温资料进行功率谱分析表明,中国气温存在明显的准两年振荡(QBO)和准3.5年振荡(称为SO)。 用CEOF方法对中国160站气温QBO和SO分量研究表明:振荡具有传播和驻波的混合。传播路径一条由华北向南向西,另一条由华南向北向西。 文章还对中国气温和东太平洋赤道海温进行了滞后相关分析。 |

| Abstract: |
| The quasi-biennial oscillation (QBO) and quasi-3. 5-year oscillation (SO) are evident in most of the 47 selected observation stations across this country after applying analyses of power spectra to their monthly mean temperature records from Jan. 1993 to Dec. 1987.A method called complex empirical orthogonal function (CEOF) is used to study the components of the QBO and SO of the temperatures in 160 stations in China, suggesting the oscillations are of mixed propagation and stationary waves. One of the propagating paths starts from North China and extends to the south and west while the other sets off trom South China, going north and west.This paper also applies analyses of lag correlations to air temperatruets in China and SST for th equatorial eastern Pacific. |
