Abstract
Analysis of the relationships between different phases of El Nio-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Madden-Julian Oscillation (MJO) with tropical cyclone (TC) activity in the North Indian Ocean (NIO) is conducted. The relationships between ENSO and IOD are compared. Statistical analysis reveals a relationship exists. Each oscillation was examined to measure its statistical significance to TC activity in the NIO. The statistical examination was performed on the phases of each oscillation singularly and then all possible phase combinations of the three oscillations occurring concurrently. Analysis through combining concurrent occurrences of climatic oscillations indicates an increased statistical significance to TC activity in the NIO.
