Influence of macroscale and regional circulation patterns on low- and high-frequency sea level variability in the Baltic Sea
Abstract The atmospheric impact on sea level variability in the Baltic Sea on different time scales was investigated. The Northern Hemisphere teleconnection patterns, namely, the North Atlantic Oscillation (NAO), Arctic Oscillation (AO) and Scandinavia (SCAND) patterns, were employed, and a strong b...
