According to the investigation materials about water bodies of Jiaozhou Bay in May, August and October 1979, this paper studies the changing process of water temperature in the surface and bottom waters. The findings show that from May to August and then to October, water temperature in the waters from inside of bay mouth to the outside forms a peak line over the time. From May to August and then to October, water temperature changes from the lowest to the highest and then drops to a relatively higher level. Based on the definition and model of Yang Dongfang temporal water temperature variation angle, the results indicate that in the water bodies of inside, around and outside of bay mouth, the Yang Dongfang temporal water temperature variation angles in the surface layer range in 75.86-78.84°from May to August, and in -70.41--77.28°from August to October. While in the bottom layer, Yang Dongfang temporal water temperature variation angle ranges in 75.47-75.61°from May to August, and in -63.99--71.27°from August to October.
