Abstract

<p> The seeder-feeder mechanism is a phenomenon in which raindrops from the upper layer catch cloud droplets in the lower layer of clouds, thus intensifying rainfall, and was considered the cause of enhanced rainfall over mountainous areas. However, in Typhoon No. 19 in 2019, the seeder-feeder mechanism was confirmed not only over mountainous areas but also over the plains. In this study, we examined the contribution of the Seeder Feeder mechanism to rainfall intensification in the mountainous area around Hakone and the Kanto plain by using an orographic rainfall estimation method based on the Tatehira model for Typhoon No. 19. The results show that rainfall enhancement by the Seeder Feeder mechanism occurred over both mountainous and plain areas. We think that this study will lead to further verification of "heavy rainfall due to stratiform precipitation with shallow convection" that may occur in the future.</p>
