半年振荡 meaning in English
half-year oscillation
Examples
- A more reasonable sao index is therefore defined as the sao variance percentage of the difference of the zonally averaged slp between 40 s and 65 s
据此，提出用40 s和65 s纬圈平均海平面气压差的半年周期分量的方差贡献作为准半年振荡的强度，该定义较前人的定义更为合理。 - Based on the ncep / ncar reanalysis products , the sea ice concentration data and the observation rainfall data in china , the seasonal , intraseasonal and interannual variations of the atmospheric circulation in the southern hemisphere ( sh ) are systematically analyzed together with their influences on east asian summer monsoon ( easm ) . the major conclusions are summarized as follows : ( 1 ) in the lower level of the troposphere , the semi - annual oscillation ( sao ) is most active along 40 s and 65 s in the extratropics of the sh . over these latitudes , the variance percentages of sao exceed 70 % , and the anti - phase variation of the sea level pressure ( slp ) between the two latitudes is primarily caused by their sao components
利用ncep ncar再分析资料、南半球海冰密度资料及中国台站降水资料，本文系统分析了南半球大气环流的季节、季节内和年际变化特征及其对东亚夏季风的影响，主要结论归纳如下： ( 1 )对南半球热带外大气环流而言， 40 s和65 s是低层大气准半年振荡最为显著的两个纬带，在这两个纬带上，半年波的贡献都超过了70 ，二者季节变化的反位相主要体现为半年波分量的反位相。
