Abstract

Variations in precipitation quantities in Galicia are related to global atmospherical circulation changes. It is obtained that NAO is the pattern that shows more correlation with rain, although other circulation patterns described by indexes such as POL, SCAN or EA have a significant contribution. This work is complemented with a study of the temporal variability in the circulation patterns. It is obtained that correlation between different indexes and precipitation varies with time. This fact can be proved studying the relationship between circulation patterns and precipitation, considering two series separated by the year 1976. It can be observed that correlation between EA and precipitation has almost disappeared in the period 1976-2000, while correlation of rain with NAO is increased.
