Being driven by strengthening winds on the opposite side of the continent
Online — New research published recently in Nature Climate Change has revealed how strengthening winds on the opposite side of Antarctica, up to 6000 km away, drive the high rate of ice melt along the West Antarctic Peninsula.
Researchers from the ARC Centre of Excellence for Climate System Science found winds in East Antarctica can generate sea-level disturbances that propagate around the continent at almost 700 kilometres per hour via a type of ocean wave known as a Kelvin wave.
When these waves encounter the steep underwater topography off the West Antarctic Peninsula, they push warmer water towards the large ice shelves along the shoreline. Continue reading
