摘要

IAP-GCM is used to document the forced teleresponse of the atmosphere to anomalies of the Antarctic sea ice as the important triggering mechanism for intraseasonal atmospheric oscillations across the globe. The time series of pentad-averaged deviations are then focused on and, with the band-pass filter approach, to address es- sential features of the 30-60 day low-frequency oscillation in the response field. It is found that the atmospheric response to the retreat of the Antarctic sea ice is of low frequency at a period of 30-60 days. The main component is the 30-60 day intraseasonal oscillation in the forced field, with the vertical structure and distribution features similar to real atmosphere.
