Field data suggest that the development of thermal stratification in the middle layer and the subsequent retardation of oxygen transport to the bottom layer is the principle mechanism in the formation of anoxia in the bottom water. The numerical model, which was developed by Nakamura and Nishimura to predict the changes of temperature and oxygen distribution, has been improved by taking account of heat exchange through the air-water interface. The improved model well reproduces the characteristic temperature variation and the dissolved oxygen content in the bottom field condition during the stratification period as well as the mixing period in autumn. Important parameters for the determination of surface heat exchange have further been evaluated by sensitivity analyses. The results show that the vapor pressure in the atmosphere and the wind velocity are the most sensitive to the total heat flux.}, pages = {69--81}, title = {内湾の熱収支と貧酸素水塊の形成について}, volume = {11}, year = {1989} }
