The IPWP as a capacitor for autumn sea ice loss in Northeastern Canada

L. Yu, S. Zhong, et al.

Discover how Indo-Pacific Warm Pool warming is driving Arctic sea ice loss in northeastern Canada, revealing a striking correlation where 45% of the observed sea ice reduction is attributable to this phenomenon. This groundbreaking research by Lejiang Yu, Shiyuan Zhong, Timo Vihma, Shuoyi Ding, Cuijuan Sui, and Bo Sun introduces the concept of the 'Arctic capacitor effect of the IPWP'.

Abstract

This study investigates the impact of Indo-Pacific Warm Pool (IPWP) warming on Arctic sea ice loss in northeastern Canada during boreal autumn. A significant negative correlation was found between the IPWP index and sea ice concentration, with IPWP warming statistically accounting for 45% of the observed sea ice loss. The authors introduce the "Arctic capacitor effect of the IPWP," suggesting that IPWP warming, driven by greenhouse gas emissions, initiates a planetary wavetrain influencing the Arctic vortex and subsequently impacting sea ice.
