Title

Circulation Statistics for the Extratropical Northern Hemisphere Based on NMC Analyses

Abstract

Polar stereographic maps and meridional cross-sections of selected circulation statistics for the extratropical regions from 1000 to 100 mb (20-90��N) of the Northern Hemisphere are presented for winter and summer. The statistics were calculated from twice daily gridded synoptic analyses produced by the U.S. National Meteorological Center (NMC) on an operational basis for 11 winters (1965-66 to 1975-76) and 12 summers (1966 to 1977). Time-filtered transient eddy and mean standing eddy variances and covariances are included together with the time-mean fields. Statistics for individual years supplement the 12 summer and 11 winter average statistics. A more extensive collection of associated grid point values is available on magnetic tape.
