| 内容記述 | In Suruga Bay the river discharge is sporadically enhanced by heavy rainfall, and its daily mean values often exceed by an order of magnitude the seasonal means. We have therefore investigated the impact of the sporadically enhanced river discharge on the climatological distribution of river water in Suruga Bay, performing numerical experiments with an ocean general circulation model. As the river discharge is enhanced, a larger amount of the Coastal Water (defined by salinity less than 33.0) is exported out of shallow areas such as the continental shelf, being less trapped by the bottom topography. Moreover, the high frequency (day-scale) variation in the river discharge causes large temporal variations of the surface salinity distribution in the bay. However, it has only a minor influence in the time-averaged field (under the same condition in terms of the total amount of the discharged river water). It is therefore suggested that in the actual sea, the high frequency (day-scale) variability in the river discharge has only a minor influence on the climatological distribution of river water in the bay. | |||||
