In the future fewer tropical cyclones may form off Western Australia but they may become more intense.
There could be a 50% reduction in the number of storms in the second half of this century – from 2051-2090 – compared to the period from 1971-2000.
However, the climate model developed by the researchers indicates a distinct shift towards more destructive storms.
“Despite a decrease in the number of tropical cyclones, there is a greater risk that a tropical cyclone that forms will be more severe in future,” CSIRO climate scientist Dr Deborah Abbs said.
“Even a small increase in cyclone intensity is concerning because of the threat to life, property, industry and agriculture.”Read more at CSIRO
