Changes in the Characteristics of Typhoons Crossing the Island of Taiwan

The article of record as published may be found at http://dx.doi.org/10.1175/1520-0493(1974)1022.0.CO;2Twenty-two typhoons (1960-72) are examined to determine the effect of Taiwan on the intensity and movement of tropical cyclones crossing the island. The results show an average intensity (maicimum surface wind) decrease of over 403 and a distinct northward deflection as the storms approach the island with a southward deflection after passage. Forecast rules for typhoons approaching or crossing Taiwan are presented

Cost Effectiveness of Typhoon Forecast Improvements

The article of record as published may be found at http://dx.doi.org/10.1175/1520-0477(1975)0562.0.CO;2Tropical cyclone forecast improvements in the western North Pacific are examined in terms of Department of Defense decision making (evacuation, sortie, preparedness, etc.). The improved decisions are then related directly to Department of Defense potential cost saving

An evaluation of the harbors of Buckner Bay and Naha, Okinawa as typhoon havens

NAVENYPREDRSCHFAC Technical Paper No. 21-75Prepared for: Naval Environmental Prediction Research FacilityAIR TASK: A370-370G/076C/6W0S33-0000 NEPRF WU: 055:3-2This study is an evaluation of the Japanese harbors of Buckner Bay and Naha, Okinawa as typhoon "havens." Characteristics of the harbors discussed include wind and wave action, storm surge and the topographical effects on winds prior to and during the passage of tropical cyclones. Problems to be considered when remaining in port and evasion procedures are examined. The tracks of tropical cyclones from 1947-1973 for the western North Pacific were analyzed to determine the probability of threat to the harbors. Observations by the authors and information obtained in conversations with harbor authorities are utilized in reaching conclusions. The conclusion reached by this study is that all vessels should evade from Buckner Bay and Naha when threatened by a typhoon.Approved for public release; distribution is unlimited
