Description
Summary:In the extratropics of the Northern Hemisphere, there exist many kinds of atmospheric teleconnection patterns. According to their spatial structure, these teleconnection patterns are generally divided into two groups. One group comprises north-south dipole patterns, such as the North Atlantic Oscillation and the North Pacific Oscillation, which have two anomalous centers of opposite signs in the north-south direction. The other group includes the wave train-like patterns, which have several anomalous centers of opposite signs distributed mainly in the zonal direction, such as the Pacific/North American and Eurasian Patterns. These teleconnection patterns greatly impact weather and climate not only in the regions where the teleconnection patterns are active, but also in the regions thousands of kilometers away. Studying and understanding the formation mechanisms of these teleconnection patterns form the basis for the short-term climate prediction. This paper reviews advances in the study of the dynamics of these teleconnection patterns, with particular attention paid to the teleconnection patterns that significantly influence the weather and climate of East Asia.
