The article explores how different regions of the world influence each other's climate patterns over time. By analyzing key climate indices and local data from Western Europe, the researchers found that the Arctic Oscillation affects the North Pacific and North Atlantic on short time scales, the North Atlantic Oscillation has a global impact over several years, the Pacific Decadal Oscillation is influenced by other factors, and local observations in Western Europe can impact ocean variability over long time scales. This study demonstrates the effectiveness of the Liang-Kleeman information flow in understanding these complex climate dynamics.
