Antarctic Temperature Changes
§ Antarctic climate is affected by Southern Annual Mode, ENSO, and
ozone hole.
§ In recent decades, Arctic climate has been affected by a trend toward
the positive phase of Southern Annual Mode, which is characterized by warm
anomalies in the Antarctic Peninsula but cold anomalies in the rest of the
continent.
§ This temperature change pattern is not projected to continue in
the 21st century, although the SAM is
predicted to be in a more positive phase. è indicating the need to consider the role of
ozone hole in the present-day peninsula warming.
