Abstract
In 1942, Dr. M. Okamoto discussed a case of the drift current in a polytropic ocean when the wind sweeps over a finite area of the surface. But, since the sea is not bounded by land in his discussion, his treatment is not exact, because Sx and Sy, where Sx and Sy mean the total flow, are used simultaneously as conditions of continuity.
Thus, in the present paper, the author tried to obtain a complete analytical solution for the problem in a rotating canal, taking account of the term of the horizontal kinematic viscosity Vx, and Vy, and that of the. vertical kinematic viscosity Vz.
