An Evaluation of the Harbors of Buckner Bay and Naha, Okinawa as Typhoon Havens.

摘要

This 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 Bya and Naha when threatened by a typhoon. (Author)
