THE WEATHER AND CIRCULATION OF OCTOBER 1968 UDC 551.506.1:551.513551.524.35 Progression of Large-Amplitude Features at Midlatitudes With Rapidly Varying Temperatures
The progression of the planetary waves as reflected in 30-day mean charts at 700 mb that had been occurring during September (Posey, 1968) continued in many areas through October. The mean trough in the Gulf of Alaska intensified further and moved to a position near 145OW (fig. 1). The ridge which h...
