PDF-DECADAL VARIATIONS IN CLIMATE ASSOCIATED WITH THE NORTH ATLANTIC OSCILLATION JAMES W

HURRELL and HARRY VAN LOON National Center for Atmospheric Research Abstract Large changes in the wintertime atmospheric circulation have occurred over the past two decades over the ocean basins of the Northern Hemisphere and these changes have had.
