A rotated eigenanalysis of the correlation between 700 mb heights and sea surface temperatures in the Pacific and Atlantic.

Abstract

One well-known atmospheric teleconnections pattern, referred to as the Pacific/North American (PNA) pattern by Wallace and Gutzler, was found in all seasons; however, seasonal differences were noted. During the warm season, the PNA pattern manifests itself as the Great Plains (GP) pattern. The GP pattern results in dry/hot (wet/cool) conditions over much of the central and eastern United States. Another, the Northeast (NE) pattern, has a center along the coast of the eastern United States and can result in dry/cool (wet/warm) weather in the Northeast. Additionally, the North Atlantic Oscillation was identified during both the cold and warm seaons. -from Author
