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
2013–14 Atlantic winter storms in Europe it explosively deepened before reaching Western Europe. Deepening below is considered uncommon in the North Atlantic, but has been recorded on a number of occasions, measured from ships transiting the ocean and from land based-recording stations. Offshore the minimum low pressure of the "Dirk" storm was forecast to reach a low of . On land the low pressure during the storm was measured at on 24 December at Stornoway, Isle of Lewis off the north west coast of Scotland. This the lowest measured in Britain and Ireland since 1886 (127 years), when a low of was recorded in Belfast, Northern
