It was determined from experimental results that the relative location of spiral vortices which appear in the transition region is fixed against the rotating sphere surface when the rotating effect is large. However as the rotating effect decreases, these vortices begin to move. So far, this phenomenon has not been explained theoretically. In this study, the boundary layer instability and the characteristics of spiral vortices are theoretically investigated by calculating the behavior of the small disturbances and the critical Reynolds number of the boundary layer on a rotating sphere using the linear stability theory.}, pages = {1895--1901}, title = {静止流体中の回転球に沿う境界層の安定性}, volume = {63}, year = {1997} }
