A seasonal variation of phytoplankton concentration is remarkable in the surface layer of the Japan Sea, because of a seasonal variation of solar radiation and nutrient. While, it is suggested that atmospheric perturbation such as typhoon effects a lower level ecosystem in the surface layer. An effect of atmospheric perturbation on the lower level ecosystem was estimated by means of an ocean general circulation model and a lower level ecosystem model in this study. Results of numerical experiments suggested that the atmospheric perturbation enhances a primary production in the Japan Sea.
