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 still is a cultural continuum in Atlantic Europe, forming a cultural unit which has its roots in prehistoric times but remained until today mostly thanks to sea trade. Geographers also mention the influence of the natural environment in the construction of a similar cultural landscape along the western European coasts. Some of the first geographers to consider this idea of Atlantic Europe were Otero Pedrayo and Orlando Ribeiro. Pedrayo stated in his studies about Galicia that this territory was marked by a strong "Atlantic character", not Mediterranean, despite the fact of being part of a Mediterranean state (Spain). On the
