Recent Research at GFDL on Surface Temperature Trends and Simulations of Tropical Cyclone Activity in the Indian Ocean Region - Monitoring and Prediction of Tropical Cyclones in the Indian Ocean and Climate Change - page 59

exceeding 33 m/s at some point in their lifetime.
response to simulated ENSO variability is quite encouraging, particularly in
the Pacific regions, and also to some extent in the Indian Ocean basins.
Summary
Present-day simulations of intense tropical cyclones in the North Indian Ocean
region are being performed and assessed as a preliminary step before climate
change simulations being undertaken. While reasonable results have been
obtained so far for the North Atlantic and Northwest Pacific basins, the North
Indian Ocean simulations exhibit a substantially larger intensity bias, including
a distribution of storm intensities that is much more clustered around ~40-50
m/s than is the case for the distribution of observed (JTWC) TC intensities in
the region.
