The NAO in winters 2002 & 2003

S. R. Dye, R. R. Dickson and J. Meincke

The North Atlantic Oscillation (NAO) index switched back to negative conditions during the winter preceding 2001 having recovered in the previous 4 years from the extreme negative value of 1996 which had brought to an end a period of extreme and persistent positive NAO index in the late 1980s/early 1990s. The 2002 NAO index showed a return to positive which for the winter as a whole was not extreme, but where individual months exhibited extreme and opposing SLP anomaly patterns. Early indications suggest that the winter of 2003 has had negative NAO index.
