The Effects of Coast and Mountain Ranges on the Direction and Velocity of Wind in Vicinity

[摘要] The mathematical treatment of the flow of air over a mountain was first attempted by Pockels with simple assumptions as to the conditions of flow together with the assumption of a periodic surface profile. Recently Mr. Arakawa studied the effects of topography on the direction and velocity of wind for the case of a mountain of semi-circular cylindrical shape lying on a flat plain.It is a well known fact that in the valley of a river the winds from the direction of the valley are frequent. At a station lying near the coast of a sea the winds having the direction perpendicular to the coastal line are most frequently observed.But, if the mountain ranges run parallel to the coastal line, near the coast, the winds of the direction parallel to the coastal line are most frequent on the coast.In this paper I studied a similar problem on the effect of mountain ranges for the case of a mountain of semi-elliptic cylindrical shape.
