The polar regions are warming at an unprecedented rate, influencing the monsoon systems (South Asian, East Asian, African) through the so-called “Oceanic Tunnels” and “Atmospheric Bridges”. These findings are based on short-term observations that don’t cover low-frequency variability. Thus, the complex interaction between climate variability in the polar regions and the tropics remains to be fully explored. Studying this teleconnection will improve our understanding of the remote factors governing the monsoons. We invite contributions studying the climate variability of the polar regions (including the Southern Ocean, Arctic Ocean, and North Atlantic Ocean) and the monsoons on decadal and longer timescales from a proxy, observation, and modelling perspective. We especially welcome contributions exploring teleconnection mechanisms between the polar regions and monsoons through various oceanic and atmospheric pathways on different timescales.
