2017 Wind Trajectories (April 1 - May 29, 2017)

THE WEEK OF MAY 29, 2017:  Wind trajectory data processing by AAFC-Saskatoon Staff began in April.  Reverse Trajectories track arriving air masses back to their point of origin while Forward Trajectories predict favourable winds expected to arrive across the Canadian Prairies for the week of May 23, 2017:

Reverse trajectories (RT)

Overall, the number of RTs entering the prairies from the Pacific Northwest has been lower than average. The map (Fig. 1) shows that the greatest number of RTs from the Pacific Northwest continued to be across southern Alberta.
