Simulation of the AAO Anomaly and its Influence on the Northern Hemispheric Circulation in Boreal Winter and Spring
Abstract The AAO anomaly and its influence on the Northern Hemispheric circulation and temperature over north of Asia are studied by analyzing the output of IAP9L‐AGCM model. First, sea temperature associated with Antarctic Oscillation (AAO) is investigated using the IAP9L‐AGCM model. The model simu...
