We've looked at this a couple times to make sure:

Whereas some meteorologists believe that there is not a link between gobal warming and storms, there has also been a recent model study on how the storm statistics can be affected by a global warming that we failed to mention in the previous discussion. Furthermore, a new analysis published in Nature by Kerry Emanuel ('Increasing destructiveness of tropical cyclones over the past 30 years') points to a high correlation between the power of the TCs and the sea surface temperature (SST). This paper is also discussed in The New Scientist. He suggests that a likely consequence of a future warming is an upward trend in the destructive potential of TCs. Emanuel argues that a net power dissipation is a better indicator of TC threat than their frequency or intensity alone.
