|a The southern hemisphere westerly winds have been strengthening and shifting poleward since
the 1950s. This wind trend is projected to persist under continued anthropogenic forcing, but the impact
of the changing winds on Antarctic coastal heat distribution remains poorly understood. Here we show that a
poleward wind shift at the latitudes of the Antarctic Peninsula can produce an intense warming of subsurface
coastal waters that exceeds 2°C at 200–700m depth. The model simulated warming results from a rapid
advective heat flux induced by weakened near-shore Ekman pumping and is associated with weakened
coastal currents. This analysis shows that anthropogenically induced wind changes can dramatically increase
the temperature of ocean water at ice sheet grounding lines and at the base of floating ice shelves around
Antarctica, with potentially significant ramifications for global sea level rise. |
