Summary The two‐dimensional dynamical equations were solved and an expression for the vertical motion was derived by assuming a balance between the pressure gradient, Coriolis and frictional forces. The frictional forces consist of terms of both vertical and lateral mixing. Isovels of the upwelling and sinking in a meridional section were obtained, assuming the magnitudes of the coefficients of the horizontal and vertical viscosities to be 10 8 and 10 2 c. g. s. respectively. The resulting vertical motion of water seems to be more intense than expected. But the result is quite flexible and reasonable values of vertical motion may be obtained by a proper choice of both the horizontal and vertical viscosity coefficients.
