A connection between mean wave height and atmospheric pressure gradient in the North Atlantic
Abstract Comparison of long‐term trends in mean wave height in the North Atlantic with values of annual mean atmospheric pressure gradient in the North Atlantic measured between the Iceland Low and the Azores High suggests, for the period of overlap between the data set of Bacon and Carter and of Sa...
