An Evaluation of Hong Kong Harbor as a Typhoon Haven.

The study evaluates the harbor of Hong Kong as a typhoon haven. Characteristics of the harbor under tropical cyclone conditions, including topographical effects on the wind, storm surge and reliability of moorings and anchorages are discussed and highlighted by two case studies Typhoon ROSE, August 1971 and Typhoon WANDA, September 1962. Problem areas to be considered if remaining in port and possible evasion procedures for ships sailing from the port are examined for tropical cyclones approaching from various directions. Tropical cyclone tracks for 87 years of data 1884-1970 for the western North Pacific Ocean are examined in order to determine the probability of threat to the port of Hong Kong. Results suggest early sortie action under threatening conditions by all Fleet units capable of evasion at sea. Author
