Caption title. Includes bibliographical reference. "The Pacific Weather Centre uses GOES satellite pictures to track cloud systems and cloud elements over North America and the North Pacific. Since the satellite is positioned over the equator at 135W longitude, the scale of the picture becomes more compressed as the distance from 0ºN 135W increases. The scale cahnges not only for every point on the picture but also for every direction from any single point. The infinitely variable scale of satellite pictures complicates the calculation fo speeds of cloud features." gccst Weather forecasts gccst Satellite imagery Canada. Environment Canada. Canada.
