Summary of Western North Pacific and North Indian Ocean Tropical Cyclones
Tropical cyclone genesis regions compared to the 10-year average are shown in Figure 1-1. This year's tropical cyclones are listed in Table 1-1. Table 1-2 shows the monthly distribution of tropical cyclones for each year since 1959 and Table 1-3 shows the monthly average occurrence of tropical storms separated into: (1) typhoons only; and (2) tropical storms and typhoons. A summary of this year's Tropical Cyclone Formation Alerts is shown in Table 1-4. The annual number of tropical cyclones of tropical storm strength or higher appear in Figure 1-2, while the number of super typhoons are shown in Figure 1-3. Figure 1-4 illustrates a monthly breakdown of system formations based on intensity categories. Composites of the tropical cyclone best tracks for the Western North Pacific appear following Figure 1-4.
