S001 流体力学からみた大気と海洋

概要

The atmosphere and oceans are thin fluid layers piled over the solid Earth which is rotating with a constant angular velocity. They are almost in rigid rotation with the solid Earth. In this sense fluid dynamical characteristics of the atmosphere and oceans have some similarity with a fluid contained in a rotating tank. However, we are interested only in the deviation from the rigid rotation, because we observe their motions on the rotating Earth. The geostrophic balance (balance between the Coriolis force and the pressure gradient) are predominant in large-scale flows. The velocities of winds and ocean currents have vertical shears due to the density stratification. As for the oceanic circulations, the westward intensification is caused by the transport of fluids with circulation (Γ) in the meridional direction along the surface of the rotating sphere.
