Interactions within the Ocean-Ice-Atmosphere Systems of the North Pacific and the North Atlantic
Four regional indices of sea ice variability and thirty years of monthly sea surface temperature (SST) and sea level pressure (SLP) data are used to evaluate the large-scale interactions within the ocean-ice-atmosphere systems of the North Pacific and the North Atlantic. A direct association between...
