Abstract
The Madden-Julian oscillation (MJO) has been documented in previous studies to significantly
impact tropical cyclone activity in all ocean basins. Most of these studies have utilized the Wheeler-Hendon
index. This index is only available since 1974, the period over which remotely sensed outgoing longwave
radiation data has been available. Our study utilizes a long reconstructed MJO index, based on surface
pressures, which extends back to 1905. We document consistent modulation of tropical cyclone activity by the
MJO in all basins over this time period. These modulations are shown to be remarkably stable over the entire
analysis period.We also examine the combined impacts of El Niņo-Southern Oscillation and the MJO on tropical
cyclone activity in each basin over multidecadal time scales.
