North Atlantic SSTs as a Link between the Wintertime NAO and the Following Spring Climate
Abstract In this paper a potential seasonally lagged impact of the wintertime North Atlantic Oscillation (NAO) on the subsequent spring climate over the European region is explored. Supported by the observational indication of the wintertime NAO–spring climate connection, a modeling approach is used...
