In the preceding paper, the author showed that the method of preventing wind damages by converting wind direction was extremely effective in localities characterized by complicated masses of hills. In the present study he investigated by model experiments how to apply this method to general cases. As the results, it was elucidated that the most effective location of the shelterbelt for converting wind direction might be a place conditioned in the following two ways or either : (1) The wind directly along the ground surface is accelarated by topographical effects, and (2) the stream line of the wind is separated easily from the ground surface being turned away by its curvature. For examples : a top of a hill, over which the wind comes ; the curving part of a hill when the wind blows along its side ; the head of a slope toward a lowland when the wind blows down ; the edge of a plateau when it blows over it ; or the narrowest part of a pass where it blows across. The shelterbelt should be especially effective when they were designed as narrow and dense as possible.
