The average precipitation is projected to increase in the whole Baltic Sea region for all seasons but summer. The largest increases are found in the central parts of the region in winter and along the Norwegian west coast. In summer precipitation decreases in the southern half of the region. In the northern part precipitation remains the same or increases slightly (0-20%). Maximum precipitation is projected to change in a similar way to precipitation (Figures 1-4, click to enlarge).
