station model heights are also plotted in tens of meters. 15. The height of the $$300?\mathrm{mb}$$ pressure level at Goodland, $$\mathrm{KS}$$ was m above sea level. a. 8956 b. 9650 c. 9560 d. 9956 16. The 300 -mb height contour pattern at $$12\mathrm{Z}$$ on 26 October exhibited an upper-air flow with a. a ridge marked by a center axis generally from Montana to New Mexico b. a broad trough with an axis from Minnesota to Louisiana c. a ridge marked by a center axis generally from Florida to Pennsylvania d. none of these fcatures This pattern is consistent with that found at $$500\mathrm{mb}$$. a. increases b. decreases c. remains constant 18. The highest wind speed in Figure $$9\mathrm{A}?5$$ occurred at Medford, OR, at kt. The wind barb includes two flags, three long feathers, and one short feather. a. 85 b. 115 c. 125 d. 135 19. Survey Figure $$9\mathrm{A}?5$$ for wind speeds of $$70\mathrm{kt}$$ or more (one flag and two long feathers). Using this threshold to define a jet stream, you can determine there evidence of a jet stream curving across the U.S. a. was strong b. was not sufficient 20. Now compare the wind speeds plotted on Figure 9A-4, 500-mb upper-air map, with those of the same areas on Figure 9A-5, the 300-mb upper-air map. Wind speeds typically as altitude increases in the troposphere. a. increase b. remain the same c. decrease 21. As seen on Figure 9A-4 and Figure 9A-5, slower wind speeds are located where spacing of height contours (isohypses) are Furthermore, the relationship is consistent with that on surface weather maps between wind speeds and the spacing of isobars. a. closer together b. farther apart 22. Compare the 500-mb and 300-mb wind flows. The pattern of wind directions also shows that the winds generally flow the greater the distance from the surface. This directional relationshi is particularly evident at higher wind speeds. a. "parallel" to the contour lines b. across contours at large angles
