Description Tropical cyclones are the most hazardous weather systems, which form over warm ocean waters. The frequencies of tropical cyclones show variabilities over all the oceanic basins, during the El-Nino and El-Nino Modoki years. Recent studies have shown significant impact of air–sea interaction processes like El-Nino and El-Nino Modoki on the cyclone activity over different ocean basins. The results suggest in most cases, El-Nino events suppress the formation of cyclones over various basins. A recent study indicated that concurrent occurrence of El-Nino Modoki and positive Indian Ocean dipole (IOD) events can generate more cyclones over north-west Pacific. We propose to study the impact of El-Nino Modoki events on the formation of tropical cyclones over north Indian Ocean (NIO). Our present study suggests that the cyclogenesis over the NIO is a complex phenomenon, as it is influenced by several coupled ocean atmospheric phenomena such as El-Nino, El-Nino Modki, IOD and Madden–Julian oscillation
