What is it about?
This study looked at how rainfall has changed in Catalonia, Spain, from 1950 to 2022. By analyzing long-term data from many weather stations, it found that overall rainfall has decreased—especially in summer—and that rainfall patterns vary between coastal and inland areas.

Why is it important?
Understanding how and where rainfall is changing helps us prepare for future water shortages, especially in regions like Catalonia that depend on seasonal rain. These changes can impact agriculture, water supply, and the risk of droughts. The findings also help us see how climate patterns like the NAO and AMO may be linked to local weather changes.
Perspectives
This study shows how long-term data and careful analysis can reveal hidden trends in our climate. The rainfall shifts observed in Catalonia may reflect wider changes happening across southern Europe. As climate variability increases, local studies like this become crucial for adapting to and managing future environmental challenges.
