An analysis of the El Nino Southern Oscillation's effects on tropical cyclones

In the 20 years, 2,023 tropical cyclones provide us a robust sample size to study the impact of the El Nino Southern Oscillation on tropical cyclone with respect to precipitation on a global scale. It is clear that the El Nino Southern Oscillation does play a significant role in the intensity, location and magnitude of tropical cyclones. We also found that the depending on which phase of ENSO and whether it’s a major or minor tropical cyclone, different parts of the globe have experienced more or less precipitation that can be attributed to tropical cyclone. How does ENSO influence frequency of tropical cyclones globally? What is the global precipitation contribution from tropical cyclones?​ How does ENSO influence global precipitation that is contributed by minor and major hurricanes?​
