Figure 11.5b shows the 500-mb chart for the same day. The 500-mb chart shows the position of highand low-pressure regions and the pressure gradient. The 500-mb chart shows how many meters above sea level the 500-mb surface is rather than showing actual pressures, as the surface chart does. Draw two red arrows to show the direction of wind between the 5340 m and 5460 m height contours, and another two red arrows between the 5580 m and 5640 m height contours. Remember that wind flows parallel to the isobars in the upper atmosphere. Draw three blue arrows between the 5820 m and 5880 m contours to show the direction of wind flowing around the centers of high pressure. 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. What will be an ideal response?
When people work much less than 8 hours per day, this is called underemployment
