Autocorrelation of Northern Hemisphere geopotential heights.

Abstract

Local autocorrelation statistics for the Northern Hemisphere geopotential height field are presented for different seasons and tropospheric pressure levels. Values are generally much higher than those calculated from time series of outgoing infrared radiation of eddy heat fluxes. The largest one-day lag autocorrelation values are observed over the polar regions and eastern oceans. Well-defined minima exist off the east coasts of Asia and North America. -from Authors
