Tropical/Northern Hemisphere Teleconnection Patterns from NOAA/Climate Prediction Center

[ Get Data ]

Abstract: [Source: NOAA Climate Prediction Center, ]

The Tropical/ Northern Hemisphere pattern was first classified by Mo and Livezey (1986), and appears as a prominent mode from November-February. The pattern consists of one primary anomaly center over the Gulf of Alaska and a separate anomaly center of opposite sign over the Hudson Bay. A weaker area of anomalies having ... View entire text
