Three-dimensional fluid flows are simulated numerically by the 3 D 15 V incompressible lattice Boltzmann model. In a rotating coordinate system, the effect of Coriolis force is incorporated into the local equilibrium distribution function at the collision stage. The force due to the pressure gradient is taken into consideration at the translating stage of the particles. The velocity fields are obtained by averaging these calculated two stage fields. The Taylor-Proudman column, the Ekman spiral and the spin-down are simulated. The existence of the Taylor-Proudman column is confirmed by the calculation. Results of the Ekman spiral and the spin-down agree well with theoretical ones obtained by an analysis with the boundary layer approximation.
