What was done
The authors studied the influence of global warming on tropical cyclones via a high resolution climate model: the T106 GCM version of the Japan Meteorological Agency global model JMA-GSM8911.
What was learned
In the words of the authors, "the results of experiments indicate that the number of tropical cyclones may significantly be reduced due to the global warming." As for the maximum intensity of tropical cyclones, they note that "no significant change has been noted."
What it means
In contradiction of the "simple thought" claims of numerous climate alarmists, even GCM studies - for an early example, see Bengtsson et al. (1996) - are beginning to demonstrate what the authors of this study call "the decrease in the global total number of tropical cyclones on doubling CO2."
