The out-of-phase inter-decadal co-variability between summer (JJA) sea ice extent (SIE) in the Kara Sea (KS) sector of the Arctic Ocean and Indian Summer Monsoon Rainfall (ISMR) is found to be weakened during the recent decades with rapidly declining SIE in the KS (since the 1980s). However, SIE in the KS and frequency of ISMR extremes are found to have a consistent out-of-phase relation during the rapidly declining SIE periods. A possible physical mechanism for the relation between the late-season ISMR extremes and summer SIE in the KS is suggested, focusing on the recent years since the 1980s.

北极海冰与晚季印度夏季季风降雨极端事件之间的可能关系

发现北冰洋喀拉海 (KS) 地区夏季 (JJA) 海冰范围 (SIE) 与印度夏季季风降雨 (ISMR) 之间的异相年代际协变在近几十年来，KS 的 SIE 迅速下降（自 1980 年代以来）。然而，在快速下降的 SIE 期间，发现 KS 中的 SIE 和 ISMR 极端的频率具有一致的异相关系。建议了晚季 ISMR 极端值与 KS 夏季 SIE 之间关系的可能物理机制，重点是 1980 年代以来的最近几年。
