Time series of tropical cyclones in the Central North Pacific basin 1966 to 2010



Figure 2-6  Time series of tropical cyclones (tropical storms and hurricanes) in the Central North Pacific basin from 1966 to 2010. Although a period of greater tropical cyclone activity occurred from the 1980s to the mid-1990s, the basin has again entered a quieter period, with fewer average annual occurrences of storms. Broken lines denote the averages for the periods 1966–1981, 1982–1994, and 1995–2010.
