1) If the earth did not rotate, how would the wind blow with respect to centers of high and low pressure (2 points) No rotation means no Coriolis Force, only pressure gradient force (and friction). This means wind would flow directly from high to low without being deflected. Friction would still slow it down at the surface, but the only reason friction changes the direction slightly is because it reduces the influence of Coriolis, so the wind isn’t deflected quite as much. 2) If the Coriolis Force causes winds to deflect to the right of their intended path in the Northern Hemisphere, why do winds in the mid-latitudes of both hemispheres generally blow from the west? (2 points) Much more simple than most made it: refer to the diagram from the lecture below. Air flow from high to low in the mid-latitudes and gets deflected to the right in the northern hemisphere and left in the southern hemisphere. This results in a wind from the west in each hemisphere. The jet streams do not CAUSE the Westerlies, they really just flow within them.
