| 摘 要： | Dynamic and numerical methods are used to discuss the atmospheric response to SST thermal
forcing. The results show that for planetary scale systems, the standing SST thermal forcing can quickly excite a
stable atmospheric equilibrium state response, which is characterized by obvious large-scale teleconnection
oscillation in east-west and south-north directions. For synoptic scale systems, the SST thermal forcing mainly
excites the atmospheric low-frequency oscillation. Some basic relation and dynamic processes between SST
thermal forcing and atmospheric response pattern are revealed and some new viewpoints are presented.
