Papers are presented on global scale circulations, the life cycles of persistent anomalies and blocking over the North Pacific, atmospheric blocking types and blocking numbers, observational characteristics of atmospheric planetary waves with bimodal amplitude distributions, and a study of eddy forcing during an Atlantic blocking episode. Topics discussed include the effect of local baroclinic instability on zonal inhomogeneities of vorticity and temperature, the forcing of planetary-scale blocking anticyclones by synoptic-scale eddies, the deterministic and statistical properties of Northern Hemisphere midlatitude circulation, and the probability density distribution of large-scale atmospheric flow. Consideration is given to stationary planetary waves, blocking, and interannual variability, the instability theory and nonlinear evolution of blocks and mature anomalies, numerical predictions of forecasts, envelope orography and maintenance of the quasi-stationary circulation in global models, numerical forecasts of tropospheric and stratospheric events during the winter of 1979, mechanistic experiments to determine the origin of short-scale Southern Hemisphere stationary Rossby waves, and sea surface temperature anomalies and blocking.
