| Abstract: |
| With emphasis on their frequency and motion characteristics, this study presents a statistical analysis of Western North Pacific tropical storms and typhoons over the 37-yearp eriod, 1946-1982. For Various intra-seasonal periods and storm intensities, charts and diagrams depict: (1)expected storm frequency-per unit area per 100-year interval; (2)resultant speed and direction oftorms; (3) mean and standard deviation of storm translational (forward) speed and (4) storm tracks upon which (1), (2), and (3) are based.Examples of the utility of the data through the application of the, Poisson and gamma distributions are presented. |
