Dominant modes of geopotential height in the northern hemisphere in summer on interdecadal timescales
Empirical orthogonal function (EOF) analysis is performed on the field of the northern hemisphere geopotential height at 200-hPa using a 54-year (1958-2011) record of summer data on an interdecadal time scale. The first dominant mode, which shows smooth semi-hemispheric variation with maximum action...
