The Indian Ocean Dipole: A Missing Link between El Nino Modokiand Tropical Cyclone Intensity in the North Indian Ocean

This study is set out to understand the impact of El Nino Modoki and the Tropical Cyclone Potential Intensity (TCPI) in the North Indian Ocean. We also hypothesized and tested if the Indian Ocean Dipole (IOD) reveals a likely connection between the two phenomena. An advanced mathematical tool namely the Empirical Mode Decomposition (EMD) is employed for the analysis. A major advantage of using EMD is its adaptability approach to deal with the non-linear and non-stationary signals which are similar to the signals used in this study and are also common in both atmospheric and oceanic sciences. This study has identified IOD as a likely missing link to explain the connection between El Nino Modoki and TCPI. This lays the groundwork for future research into this connection and its possible applications in meteorology.
