Abstract

The accumulated precipitation in February, March and April over the Iberian peninsula has been analysed because a decreasing trend was identified in February and March, it is higher towards southern part of the peninsula. The precipitation variations were characterized by means of principal component analysis and the associated time series were related to teleconexion and sea surface temperature (SST) indices like El Nino˜ and SST over global tropical regions (10S-10N). There is a correspondence between the decreasing precipitation and the increasing of the Arctic oscillation, El Nino˜ and the tropical SST.
