Boundary current a basin (such as the Gulf Stream, a current on the western side of the Atlantic Ocean) are stronger than those on the eastern boundary (such as the California Current, on the eastern side of the Pacific Ocean). Western intensification was first explained by the American oceanographer Henry Stommel. In 1948, Henry Stommel published a paper in "Transactions, American Geophysical Union" titled "The Westward Intensification of Wind-Driven Ocean Currents", in which he used a simple, homogeneous, rectangular ocean model to examine the streamlines and surface height contours for an ocean at a non-rotating frame, an ocean characterized by a constant
Atlantic Europe parts of Scandinavia and the Baltic), resulting in similar landscapes with common endemic plant and animal species. From a strictly physical point of view most of the Atlantic European shoreline can be considered a single biogeographical region. Physical geographers label this biogeographical area as the "European Atlantic Domain", part of the Euro-Siberian botanic region. The Atlantic Bronze Age is a cultural complex of the Bronze Age period of approximately 1300–700 BC, that marked the economic and cultural exchange between the current territories of Portugal, Spain, France, Great Britain and Ireland. Via the Bell Beaker culture, Atlantic and Central Europe were
