associated with the circulation patterns shown in figure 11. During winter the very strong ridge and northerly direction of the height arionialy (fig. 11A) favored repeated, strong outbreaks of Arctic air masses. In spring (fig. 11B) heights were below nornial in western Canada and there was a trough along the west coast. These conditions encourage warmth east of the Rockies. Compared with the winter season, spring was rather unspectacular with few new records. Reno, A’ev., reported the wettest spring since records began with inore than three times norinal rainfall associated with the coastal trough. Other records include the warmest spring at
