Abstract:Some numerical experiments were made to examine the possibility of large anticlockwise circulation at Lake Biwa in summer caused by horizontally uniform heat flux across the lake surface. Flow is induced by the “topographic heat accumulation effect” due to the non-uniform water depth. To evaluate this flow, an axisymmetric model basin is used. Dependence of the magnitude of velocity on the horizontal and vertical Ekman numbers is also investigated. If the heating continues as long as the vertical diffusion time, fairly large velocity is created indicating a possibility that this is the origin of the lake current.
