ES1905  Observe how the Coriolis effect influences wind direction.

Air flows from areas of higher pressure to areas of lower pressure. Based on this fact, the predicted wind direction for the area on the left side of this satellite image would be from the southeast.

The Coriolis effect influences wind by deflecting its path to the right in the Northern Hemisphere. The sequence of weather satellite images shows that the actual wind direction is from the southwest. The satellite images show atmospheric motion over the northern Pacific Ocean for a 36-hour period.
