基于30年大气模式比对项目（AMIP），利用IAP AGCM4.0对东亚副热带西风急流（EASWJ）与东亚夏季降水的关系进行了研究，并与观测结果进行了比较。模式模拟和观测结果均表明，EASWJ经向位移与东亚地区降水的关系更为密切，异常南移有利于江淮流域降水，异常北移导致江淮流域降水减少。然而，模拟降水异常比综合分析观测到的要弱，这可能与中高纬地区重现较弱的中高层辐合和低纬度地区的上升运动有关。
Abstract Based on a 30-year Atmospheric Model Intercomparison Project (AMIP) simulation using IAP AGCM4.0, the relationship between the East Asian subtropical westerly jet (EASWJ) and summer precipitation over East Asia has been investigated, and compared with observation. It was found the meridional displacement of the EASWJ has a closer relationship with the precipitation over East Asia both from model simulation and observation, with an anomalous southward shift of EASWJ being conducive to rainfall over the Yangtze-Huaihe River Valley (YHRV), and an anomalous northward shift resulting in less rainfall over the YHRV. However, the simulated precipitation anomalies were found to be weaker than observed from the composite analysis, and this would be related to the weakly reproduced mid-upper-level convergence in the mid-high latitudes and ascending motion in the lower latitudes.
