Short Summary

This study analyzes the individual and combined impacts of the North Atlantic Oscillation (NAO) and East Atlantic (EA) patterns on monthly precipitation in mainland Spain from 1950 to 2020, concluding that their joint influence provides a more comprehensive understanding of precipitation variability than independent analysis.

Objective

• To investigate how individual and combined NAO and EA phases influence monthly precipitation patterns across mainland Spain.

Study Configuration

• Spatial Scale: Mainland Spain.
• Temporal Scale: Monthly intervals from January 1950 to December 2020.

Methodology and Data

• Models used: Spatial correlation analyses and precipitation deviation mapping.
• Data sources: MOPREDAScentury dataset.

Main Results

• Combined NAO/EA phases produce distinct precipitation signatures, with the highest spatial coherence observed during the winter season.
• Concurrent NAO−/EA− phases are associated with significantly wetter conditions.
• NAO+/EA− phases generally result in drier conditions across much of the region.
• The influence of the NAO diminishes during the summer, whereas the EA becomes a more dominant control on precipitation variability.

Contributions

• Establishes that the combined analysis of the NAO and EA indices offers a more complete understanding of precipitation variability than analyzing either teleconnection independently, providing a basis for improved seasonal forecasting, drought preparedness, and water resource management.
