This research concerning the North Atlantic Ocean is trying to establish a link between the extreme hurricanes (categories 4 and 5) activity and the global warming over the period 1945-2018. The hurricanes intensity has been estimated from 1945 to 1977 with the aircraft reconnaissances. These data come from the Hurdat database of National Hurricane...

This research concerning the South Pacific Ocean shows the 10-year and interannual variability of extreme cyclones (categories 4 and 5). The intensity of these cyclones has been reanalysed on the basis of GMS, GOES and NOAA satellite images with the Dvorak technique. In the period 1980–2016, 63 cyclones reached categories 4 and 5. During the decade...

This research concerning the northern Indian Ocean demonstrates the variability of intense tropical cyclones (categories 35) both on an inter-annual and intra-seasonal scale. All the cyclones intensity have been re-analysed with the Dvorak technique using both National Oceanic and Atmospheric Administration and geostationary satellites with a 4-km...

The North Indian Ocean (NIO) is not considered as one of the more active tropical cyclone basins. On average each year, only five or six systems reach at least the tropical storm stage, 35 knots or more (Singh et al. 2001). In the current debate on global warming and the evolution of the intense cyclones number, studies have given different results...
