Mechanism of the Indian Ocean Tropical Cyclone Frequency Changes due to Global Warming - Monitoring and Prediction of Tropical Cyclones in the Indian Ocean and Climate Change - page 48

mainly due to the non-uniform SSTA effect. The decreased vertical wind shear
seems to be responsible for the increase in TC frequency in the Arabian Sea,
while the increased upward mass flux associated with the enhanced precipitation
is responsible for the increase in TC frequency in the South Indian Ocean.
