2009 southeastern Australia heat wave: Difference between revisions

The heat wave was caused by a slow-moving high-pressure system that settled over the Tasman Sea. Coupled with an intense tropical low and a monsoon trough over Northern Australia, this produced hot, tropical air to be directed over southeastern Australia, raising temperatures significantly. The [[CSIRO]] stated that "The warm lower tropospheric anticyclone is the key synoptic weather system responsible for the heat-waves."<ref>{{cite web|title=The Meteorology of Australia's Heat Waves|url=http://www.cawcr.gov.au/events/modelling_workshops/workshop_2009/presentations/McBRIDE_2DEC.pdf|accessdate=14 February 2014|archiveurl=https://web.archive.org/web/20100925045004/http://www.cawcr.gov.au/events/modelling_workshops/workshop_2009/presentations/McBRIDE_2DEC.pdf|archivedate=25 September 2010}}</ref> The heat wave was the worst in Australia's history and raised extensive debate over the [[effects of global warming on Australia|effects of global warming on the country]].
