Mean rainfall characteristics of tropical cyclones over the North Indian Ocean using a merged satellite-gauge daily rainfall dataset
The tropical cyclones (TCs) formed over the North Indian Ocean (NIO) have paramount socio-economic impacts over India and neighbouring countries due to heavy rainfall, strong wind and high storm surge. In this...

Open AccessChanges in the thermodynamical profiles of the subsurface ocean and atmosphere induce cyclones to congregate over the Eastern Arabian Sea
The Arabian Sea accounts for a small fraction of Tropical Cyclones—about 2% of the annual global mean. However, the damage they might inflict there and along its coastlines, which are thickly populated, is con...

Open AccessPacific decadal oscillation causes fewer near-equatorial cyclones in the North Indian Ocean
Tropical cyclones do not form easily near the equator but can intensify rapidly, leaving little time for preparation. We investigate the number of near-equatorial (originating between 5°N and 11°N) tropical cy...
