This atlas presents atmospheric general circulation statistics derived from twelve years (1979-1990) of daily National Meteorological Center (NMC) operational geopotential height analyses; it is an update of prior atlas using data over 1979-1986. It consists of a concise climatology of dynamical quantities throughout the troposphere and stratosphere, as a climatology of planetary wave statistics, and to alert potential users to the availability of these data.
