摘要:

The viscous flow past a right circular cylinder on a β-plane is numerically studied. The basic flow, unbounded laterally, is assumed to be uniform. The explored parameter space isRo<O(1),Ek≪O(1),∼O(1) and δ=2, whereRois the Rossby number,Ekthe Ekman number,the beta parameter, and δ the aspect ratio. Under these conditions, the quasigeostrophic potential vorticity equation is integrated numerically.
