Autumn 2011 will go down in the record books as Australia's coolest autumn since at least 19501, figures released from the Bureau of Meteorology's National Climate Centre show today.
Nation-wide, autumn 2011 beats the previous record low set in 1960 (-0.95°C), with temperatures -1.15°C below the 1961-1990 average. The abnormally cool temperatures are largely the result of the strong 2010/11 La Niña event which brought heavy rainfall and cool daytime temperatures to Australia, before decaying in late autumn. Of the five coolest autumns nation-wide since 1950, four have occurred during or following La Niña events.
The record cold autumn ends a quite remarkable sequence of extremes for Australia as a result of the strong La Niña. >> More
