Teleconnection between the Antarctic sea ice and the tropical climate has been extensively investigated. This study examines the interannual relationship between the variability of sea ice extent in the Indian Ocean sector (20–90°E) and Indian summer monsoon rainfall under the influence of the Mascarene High. Sea ice extent during April-May-June (AMJ) appears to have a significant correlation with the summer monsoon rainfall over Peninsular India region during June-July-August-September from 1979 to 2013. Composites of mean sea level pressure (MSLP), 500 hPa geopotential height, and 850 hPa wind anomalies during high and low ice phases show a positive relation between the sea ice extent and the Mascarene High, revealing that high (low) ice phase corresponds respectively to the strengthening (weakening) of the Mascarene High as well as an increase (decrease) in Indian summer monsoon rainfall. During the respective high (low) ice phase years, positive (negative) MSLP anomalies were found, particularly over the Mascarene High region, associated with the eastwards (westwards) shifts of its climatology locations. Similar features were observed at 500 hPa geopotential height anomalies. In addition, strong anticyclonic (cyclonic) anomalies in the Mascarene High region were found in 850 hPa winds, which led to corresponding strong (weak) south westerlies and thus respective positive (negative) Indian summer monsoon rainfall anomalies.

南极海冰与热带气候之间的遥相关已被广泛研究。这项研究研究了在印度洋Mascarene High影响下，印度洋海域（20-90°E）海冰范围的变化与印度夏季风降雨之间的年际关系。1979年至2013年6月至7月8月至9月期间，印度半岛地区的夏季季风降雨似乎与4月至5月6月（AMJ）期间的海冰范围密切相关。平均海平面压力（MSLP）的组合，在高冰期和低冰期，地势高度为500 hPa，风场异常为850 hPa，这表明海冰范围与Mascarene High呈正相关，揭示了高（低）冰期分别对应于Mascarene High的强化（减弱）以及印度夏季季风降雨的增加（减少）。在相应的高（低）冰期年中，特别是在Mascarene High地区发现了正（负）MSLP异常，这与气候位置的东移（西移）有关。在500 hPa的地势高度异常中观察到了相似的特征。此外，在850 hPa的风中发现了Mascarene High地区的强反气旋（气旋）异常，这导致相应的强（弱）南西风，因此分别引起了印度夏季风的正（负）雨异常。发现MSLP呈正（负）异常，特别是在Mascarene High地区，这与气候位置的东移（西移）有关。在500 hPa的地势高度异常中观察到了相似的特征。此外，在850 hPa的风中发现了Mascarene High地区的强反气旋（气旋）异常，这导致相应的强（弱）南西风，因此分别引起了印度夏季风的正（负）雨异常。发现MSLP呈正（负）异常，特别是在Mascarene High地区，这与气候位置的东移（西移）有关。在500 hPa的地势高度异常中观察到了相似的特征。此外，在850 hPa的风中发现了Mascarene High地区的强反气旋（气旋）异常，这导致相应的强（弱）南西风，并因此导致了印度夏季风的正（负）异常。
