简介：使用每月的风和海面温度(SST)数据，在印度洋与印度洋偶极子模式(IOD)事件联系的南部的南方的大气循环房间第一次被描述并且检验。分叉的风和压力vertical速度为大气循环房间的鉴定被采用。在积极IOD事件的四个不同阶段期间，在西方的印度洋上的异常南方的哈德利发行量证明空气在更低的对流层在热带，在上面的对流层的流动杆病房，在画热带的水池，和回来升起回到热带。在东方印度洋上的塞诺马劳斯·哈德利循环在西方的印度洋上对那相反。在积极IOD事件期间，当它在西方的印度洋上被加强时，在东方IndianOcean上的南方的哈德利发行量被削弱。在IOD索引和哈德利房间的索引之间的相关分析也证明那，大气循环模式在在记录的时期上的每个IOD事件是明显的。
