Chan and Liu (2004) argue that current models are not yet sufficiently good for addressing the question regarding global warming and typhoons (A typhoon is technically the same as a hurricane, the difference being that they form over the western Pacific or the Indean Ocean).

If you look just at SST changes, the maximum wind speed can be estimated by modeling the hurricane as a Carnot cycle heat engine.

All in all the science of hurricanes does appear to be much more fun and interesting than the average climate change issue, as there is a debate, a «fight» between different hypothesis, predictions compared to near - future observations, and all that does not always get pre-eminence in the exchanges about models.
