Questions 5 and 6 involve upper-level or geostrophic winds, which occur higher than 500 m (1600 ft).

Draw the pressure-gradient force in red, Coriolis force in green, and the resulting flow of wind in blue, from the two high-pressure cells toward the low-pressure cell in the center of Figure 11.5a below.
