Antarctica influencing weather in tropics

  1. Context: Scientists are coming to grips with how weather in Antarctica is influencing climate as far away as the tropics
  2. Relevance: Researchers discovered an influence of atmospheric circulation in the Wilkes Land and Ross Sea regions of Antarctica on
    precipitation from the East Asian monsoon
  3. The News: The Atmospheric Radiation Measurement West Antarctic Radiation Experiment (AWARE) project gains importance
  4. Study: How climate change and associated atmospheric physics are affecting Antarctica
  5. Result: An expanding Hadley cell is generally expected to result from a globally warming atmosphere
  6. So the Antarctic warming from cloud property change is a positive feedback on a warming climate
