FIGURE 6.43 Laboratory Evercse 7 Isobars of sea-level pressure at 182on February 17, 1992 1024 1020 1020 1024 G 1020 1024 1012 1028 1016 J008 1004. 1024 1020 1016 7. In Figure 6.43 you are given isobars of sea-level pressure. (a) Mark any centers of high and low sea-level pressure with an "H" or "L." (b) At each location marked with a dot, use the isobars to estimate the wind direction. Indicate your answers by drawing the wind direction portion of the station model (assume that the dots are thee cloud circles). (c) Based solely on the spacing of the isobars, arrange points D, E, and F in order of increasing wind speed. 8. Figure 6.44 shows isobars at 4Z on January 8, 1998 (a) Mark any centers of high and low sea-level pressure with an "H" or an "L." Mark any troughs with a dashed line and any ridges with a serrated line (that is, use the same symbols as in Figure 6.14b). (b) Using the isobars, draw a dozen or so arrows around the low-pressure area in the east to show the wind flow around this storm. Using your arrows, conclude which side of a low (west or east) would tend to have southerly winds, and which side would tend to have northerly winds. Therefore, which side would tend to be the warmer side and which side the colder? 236 VA.

Answer 1

A) and B) parts are shown in the figure attached below:

1024 1020 1020 1024 1020 1024 J012 ro28 1016 J008 H T004 1024 1020 1016

c) If the isobars are closely spaced then this will have more velocity gradient and thus will have higher wind velocity and if they are placed widely then they will have lower gradient and thus low wind velocity and therefore the fastest wind speed is at D and slowest is at F and intermedia at point E.
