Abstract
In order to maintain the water environment of the inner bay, material cycle in water has to be made clear in physical, chemical and biological aspects. Wind blowing over water surface is one of the major factors that change the flow distribution in the bay. It is important to estimate the spatial variation of wind as appropriate as possible.
In this study, numerical weather model (WRF) was used for the estimation of temporal and spatial variation of wind and atmospheric pressure at and around the inner bay. And tidal current simulations were carried out using wind distribution calculated by WRF. The results obtained from the application to IMARI bay shows that WRF simulates the observed meteorological variations, such as diurnal variation of wind and temporal changes of atmospheric pressure, with acceptable errors. Furthermore, the spatial distribution of residual currents changes depending on the wind condition given as computational condition. It was implied that the weather condition in the computational area needs to be accurately estimated and WRF which can take the topography around coastal area into account is effective for calculating the airflow at inner bay.
