Range and Standard of Yang Dongfang Spatial Water Temperature Variation Angle I. Spatial Water Temperature Model Calculation

Abstract According to the investigation materials in the water field of Jiaozhou Bay in May, August and October 1979, this paper studies the rise, decline and changing process of water temperature in the surface and bottom waters. The findings show that in the spatial changing process from May to August, then to October, the temperature in the surface water exhibits valley to peak line, then to the growth line and exhibits drop line to growth line in the bottom water from the bay inside to the waters of bay and to the outside waters. Based on the definition and model of Yang Dongfang spatial water temperature variation angle, the computerization result indicates that from May to August, the range of Yang Dongfang spatial water temperature variation angle from the water inside of the bay to the water around the bay mouth in the surface water is -0.57-0.57°, and it is 0.00--13.49°in the water from bay mouth to the outside, which are 0.00-6.27°and -4.00-0.00°in the bottom water, respectively.
