March 24, 2009 The weather conditions that lead to Southern Australia’s past two devastating bushfires may be linked to lower than normal sea-surface temperatures in the eastern Indian Ocean, according to CSIRO research presented at the Greenhouse 2009 Conference today. The Ash Wednesday bushfires in February 1983 and the Black Saturday bushfires in February were preceded by months of very dry conditions. Those dry conditions were partly caused by cooler ocean sea-surface temperatures in the eastern Indian Ocean, which contributed to a substantial reduction in spring-time rainfall over the south-east of Australia.
