Abstract
Many apples dropped by a Typhoon 9119 in Aomori Prefecture, and farmars sustained great damege. The state of fruit drops are regional differences, therefor it is considered that the flow of wind is influenced by the cinfiguration of the ground. The flow patterns on the relief model of Aomori Prefecture are visualized by a smoke-wire method, and the scale of eddy and the period of vortex shedding in behind the Mt. Iwaki have been obtained from it.
