The maps opposite show rainfall
patterns
for
Sep-Oct-Nov
(southern hemisphere spring) and
for
Dec-Jan-Feb
(southern
hemisphere winter) generated
from a merged analysis of
precipitation from 1979 to 2003.
The top row shows the average
daily rainfall that prevails for the
given
period
and
ENSO
conditions. Darker colors indicate
more rain.
The bottom row shows how the
values in the map above compare
to the overall average for that
season. Blue colors designate
areas which receive more than
average rain during the above
mentioned ENSO conditions (see
title). Brown colors designate
areas which receive less rain.
