This paperdescribes contribution of strongwind events onDissolved oxygen (DO) concentrations inTokyo Bay by statistical analysis. Tokyo Bay is a typical enclosed bay in Japanwhose water quality has been deteriorated. For example, the occurrence of anoxic water in the bay head adjacent to the seabed is frequent. Since estuarine circulation dominates DO concentration and a strong wind event is revealed toenhance recoveringprocesses of DO concentration, thisstudy aims to understandstatistical characteristics of strong windeventson DO concentration in Tokyo Bay. Strong windperiod, interval and intensity were tested as indicator of strong wind events' statistics. As a result, pdf analysishas potential in the evaluationof the recovery processes ofDO concentration around the headofTokyo Bay. Strongwind events werealso revealed to appearfrom May to August dominantly.
