| 摘 要： | The forcing of anomalous divergent wind and transient vorticity fluxes to the anomaly ofstationary waves of DJF (December—January—February) 1982/1983 is studied.The results showthat the anomaly of the transient vorticity flux convergence tends to cancel or dissipate the anomalyof the vorticity sources generated by divergent wind.The stationary wave anomalies are maintainedby both of these forcings.It is also found that,for the DJF 1982/1983 case,both of the vorticitysource anomaly over the tropical and equatorial eastern Pacific and that over the midlatitude NorthPacific are important to maintain the atmospheric circulation anomaly over the Pacific/NorthAmerica region.
