In a statistical analysis of more than a century of data, a strong connection was found between strong warm El Niño winter events and high spring precipitation in a band from southern England eastwards into Asia. This relationship is an extension of the connection mentioned by Kiladis and Diaz (1989. ‘Global climatic anomalies associated with extremes in the Southern Oscillation’, J. Climate , 2 , 1069–1090), and is much stronger than the winter season teleconnection that has been the subject of other studies. Correlation coefficients between December–January (DJF) NIÑO3 indices and March–May (MAM) precipitation are higher than r =0.3 for individual stations, and as high as r =0.49 for an index of precipitation anomalies around 50°N from 5°W to 35°E. The lagged correlation suggests that southeast Asian surface temperature anomalies may act as intermediate variables. Copyright © 2000 Royal Meteorological Society
