摘要:
The barotropic vorticity equation in the presence of time-dependent localized external excitation is investigated using the weakly nonlinear approach. Conditions for linear and nonlinear resonance are found. Under certain conditions steady rectified currents can be excited yielding an effectively steady state response to time-dependent excitation. The applicability of the results to the blocking phenomenon is discussed.
