在南极摆动(AAO ) 和西方的 NorthPacific 台风数字(WNPTN ) 在之间的关系内部年度可变性在这研究被检验。TheWNPTN 为 thedetrended 时间系列在 -0.48 在 1949-1998 在 June-July-August-September (JJAS ) 与 AAO 被相关,在 99% 水平统计上重要。在与 AAO 过时的人或物分析了联系的西方的太平洋上的热带大气的发行量以及海表面温度可变性。因而, JJAS AAO 的一个积极阶段对应于垂直的带的风的更大的大小砍,异常低杆的逆旋风的发行量和anomaloushigh水平气旋的循环,和在在西方的诺思太平洋的主要台风开始区域的更低的海表面温度,因此为台风开始提供相反的环境,并且反过来也如此。
Relationship between the Antarctic oscillation (AAO) and the western North Pacific typhoon number (WNPTN) in the interennuel variability is examined in this research. The WNPTN is correlated with the AAO in June-July-August-September (JJAS) in 1949-1998 at -0.48 for the detrended time series, statistically significant at 99% level. The tropical atmospheric circulation as well as the see surface tamperature variability over the western Pacific associated with AAO has been analyzed. It follows that e positive phase of JJAS AAO corresponds to the larger magnitude of the vertical zonal wind shear, the anomalous low-lever anti-cyclonic circulation end anomalous high-level cyclonic circulation, end lower see surface temperature in the major typhoon genesis region in the western North Pacific, thus providing unfavorable environment for the typhoon genesis, end vice versa.
