摘要

Abstract

Sharples's 1-D physical model

employing tide-wind driven turbulence closure and surface heating-cooling physics

was used to simulate the evolution of seawater temperature in the central part of Jiaozhou Bay. The results were consistent with observation after application of a large value of vertical eddy diffusivity to the upper layer in the case of rainy season. The simulated bottom seawater temperature varies regularly in sinusoidal pattern. The simulated surface seawater temperature clearly indicates that stratification begins in the middle of April

lasting about 6 days

and ends in later August

lasting only 2 days; and that the strongest stratification occurs in June

when the surface net heat flux is close to zero. Since the rainfall process not considered in the present model could cause very strong vertical mixing in the upper layer of bay water

the physical meaning of applying a larger vertical eddy diffusivity is supposed to be a parametrization of the rainfall created mixing in the upper layer. To prove this hypothesis more complex models have to be used and more observations have to be made in future study.
