 Regional Rainfall Trends
Australia's annual mean rainfall has increased
slightly over the last century.
Most of this increase has been in the northwest and southeast, as
shown by the timeseries of annual mean
rainfall for the four quadrants of
Australia divided by the lines 135°E and 26°S.
The northeast and southwest quadrants of Australia show little or no trend
since 1900. The southwest quadrant has the lowest mean annual rainfall
while the northeast displays the largest year-to-year variability.
