North Atlantic atmospheric and oceanic indices predicting the winter anomalous european rainfall
Abstract
The leading European winter precipitation anomalous pattern, connected to a NAO-like structure, has been related to a sea surface temperature structure which subtropical branch presents a significant persistence from the previous five months, having an important predictive value. Also, the Northern polar vortex presents a significant predictive skill describing this precipitation structure with 20 days in advance. These two indices and other atmospheric and oceanic indices are going to be analyzed in this work, in order to stablish their predictive value on the winter European precipitation. Also, simple predictions of some extreme cases, using these indices, are going to be analyzed in this work.
