3. Questions 3and 4 involve patterns of wind at the
surface, where wind moves al a 45-degree angle to the pressure
gradient force. Draw the pressure-gradient force in red,
Coriolis force in blue, friction in brown, and the resulting flow
of wind in blue, from the two high-pressure cells toward the
low-pressure cell in the center of Figure 11
4a below.

4. Figure 11 4b shows the surface pressure conditions on October
18, 2007. Using a red pend 1. draw at least two arrows lo 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, end 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 lo 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.
