Question 853

Is the jet stream flowing in the same direction in the southern hemisphere as it is in the northern hemisphere? — LS, Ashland, OR
The jet streams flow eastward in both hemispheres. Their directions of flow are determined by the Coriolis effect, in which high-altitude winds that are heading away from the equator veer eastward because of their angular momentum on the spinning earth.
