Caption title. "During the late sumer and fall of 1979, there were several instances of 'Blocking Highs' off the west coast These patterns resulted in several weeks without any recorded precipitation over the Vancouver area. The change in weather after such a dry spell usually happens fairly quickly and is often difficult to forecast. An attempt was made to discover a general pattern preceeding the imminent breakdown of such a block. Several similar breakdowns were examined using satellite imagery." gccst Weather forecasts gccst Satellite imagery Canada. Environment Canada. Canada. Atmospheric Environment Service. Pacific Region.
