Impact of the Icelandic Low on British climate in winter
Abstract Correlations of the North Atlantic Oscillation (NAO) with climate variables in continental Europe are strong but weak over Britain. This article presents evidence that interannual variations of British climate are explained more successfully by variations of the Icelandic Low (IL), the nort...
