Figure 11.4b shows the surface pressure conditions on October 18, 2007. Using a red pencil, draw at least two arrows to show the directions of winds flowing from the high-pressure center over Idaho and Nevada into the low-pressure center off of the Pacific Northwest, and draw two more arrows showing the directions of winds flowing from the same high-pressure center into the low-pressure center over Iowa. Remember that surface winds flow at a 45° angle to the pressure gradient. Draw at least two red arrows to show wind flowing out of the high-pressure center off the east coast toward the low-pressure center over Iowa. Using an orange pencil, shade at least two regions with closely spaced isobars, indicating a steep pressure gradient. Using a green pencil, shade at least two regions with
widely spaced isobars.
