Changes in tropical cyclone (TC) activity from climate model projections for the period 2000-2060 are compared for the cases of (i) no scenario change (CNTRL) and (ii) the moderate IPCC SRES A1B scenario (EGHG). The region of interest is the economically important northwest Western Australia TC basin (Equator-40S; 80-140E).
A new approach to tracking tropical cyclones in model simulations is presented, based on the nested Regional Climate Model in tropical channel configuration. It is found that there was little difference in the mean TC numbers over the period but that there is a statistically significant difference in the mean intensities.
