Increased Frequency North Indian Cyclones

The generally low number of cyclones in the North Indian Ocean and historical data limitations make it difficult for scientists to identify observational trends. However, models commonly show a substantial increase—by 46 percent—in cyclone frequency over the Arabian Sea by the end of the 21st century. The occurrence of back-to-back cyclones in 2015 off the coast of Yemen—first with Category 4 Cyclone Chapala followed shortly after by Category 3 Cyclone Megh—is consistent with model predictions.
