In this report, we present the results from our recent experiments using 20 km-mesh and 60 atmospheric general circulation models with prescribed sea surface temperatures (SST). The of consistently show a reduction in global tropical cyclone frequency due to warming. By different resolution SST changes, find that warming is very robust feature. contrast, regional change varies lot among distribution. We sensitive relative This suggests strongly affected by convective activity which dominated distribution patterns, therefore, for reliable projection change, pattern vitally important.
