Chronique annuelle des composantes XGRP et YGRP du gradient régional de pression (GRP) et de la pression atmosphérique au niveau de la mer au point de grille 5°E - 50°N sur la période 1970-2011. XGRP et YGRP ont été calculés à partir de la pression au niveau de la mer et d’une grille de 2,5° de résolution. Annual series of the XPGF and the YPGF components of the « pressure gradient force » (PGF) as well as of the sea level pressure for the grid point 5°E - 50°N over the 1970-2011 period. XPGF and YPGF were computed with the sea level pressure data at a grid resolution of 2.5°.
