List the information that can be derived from studying the direction and spacing of contour lines and isobars

Question

What will be the ideal response?

Answer 1

ANSWER: Contour lines are lines connecting points of equal elevation, and with regard to pressure readings this means that each contour line tells the altitude above sea level at which a certain pressure reading can be obtained. In areas where pressure surfaces dip rapidly due to the changing air temperatures the contour lines are crowded together, whereas in areas of little horizontal temperature change, there are also fewer contour lines. Although the contour lines are lines of constant height, they illustrate pressure (as do isobars) in that contour lines of low height represent a region of lower pressure and contour lines of high height represent a region of higher pressure.

Wind direction can be determined by studying the orientation of isobars or contour lines; its speed can be estimated from the spacing of the isobars. If we know the isobar or contour patterns on an upper-level chart, we also know the direction and relative speed of the wind, even for regions where no direct wind measurements have been made. Similarly, if we know the wind direction and speed, we can estimate the orientation and spacing of the isobars, even if we don’t have a current weather map.
