Weather Map Analysis 500-mb Maps 15. How does the spatial pattern of heights illustrate the The 500-mb map generally includes the same raw data, contours, and isotherms as the 850-mb map. Occasionally, vorticity (a measure of eddies in the general wind flow) is also depicted. Maps at this level help to show how storms will move, since the speed and direction of 500-mb winds steer their paths. relationship between temperature, density, and the rate of vertical pressure change 13. What contour interval is used to show heights on the 500-mb map in Figure 16 16. If a surface low pressure center developed in the Oklahoma panhandle, in which direction would it likely move? 14. What range of heights do you see on the 500-mb map? 20 5340 5400 5460 700 5640 5340 $280 520 5580
Explanation / Answer
13. The contour interval in the map is 60 meters.
14. The height range of the map is 5220 meters to 5880 meters
15. The temperature in the 500mb charts mostly never drop below zero degrees centigrade. The density distribution however changes depending on the "Vorticity" of the map. That is if the lines are spaced close to each other, the density changes rapidly and vice versa. The pressure change will be more vertically if the lines are spaced close to each other.
16. If a low pressure system forms over Okhlohoma, the system would move north easterly as the upper winds are north easterly.
