Combined effect of the QBO and ENSO on the MJO

论文摘要

本文研究了平流层准两年振荡与ENSO对MJO的协同作用。结果显示:在拉尼娜/准两年振荡东风位相,起源于印度洋到达西太平洋的MJO要比在厄尔尼诺年强。但是在拉尼娜/准两年振荡西风位相,这种关系不复存在。原因在于ENSO和准两年振荡对MJO事件的影响不同。厄尔尼诺年西太平洋地区正水汽平流有利于MJO加强,而准两年振荡西风位相下海洋性大陆地区较强的日循环会使得海洋性大陆屏障作用增强。在厄尔尼诺年,尽管MJO在准两年振荡西风位相下会受到抑制,但是在到达西太平洋是都能得到加强。在拉尼娜/准双周振荡的西风位相下,海洋性大陆较强日循环和西太平洋不利的背景条件都会抑制MJO。
