This atlas is presented for a concise climatology of important dynamical quantities throughout the troposphere and stratosphere, as a climatology of global planetary wave statistics, and to alert potential users to the availability of these data. This document presents monthly means, along with daily and interannual variabilities of various circulation statistics derived from these data: zonal mean temperatures and winds, poleward heat and momentum fluxes, Eliassen-Palm flux divergences, and stationary and transient planetary wave statistics. Horizontal winds are derived from the geopotential fields via a method which gives significant improvements over local geostrophic values in the stratosphere. Meridional cross sections are presented for each month, along with Northern Hemisphere and Southern Hemisphere polar stereographic projections at various pressure levels for January, April, July, and October. Climatological latitude-time and heighttime cross sections are displayed which highlight seasonality, along with a series of diagrams for each year which illustrate the true daily variability. Finally, tables of monthly mean temperatures, zonal winds, and amplitudes and phases of stationary zonal waves 1-3 are given for reference.
