On a Surface Analysis Chart, the lines that depict sea level pressure patterns are called what?

• A. Contour lines
• B. Isotherms
• C. Isobars
• D. Isohyets

Answer: (C)

In meteorology, sea level pressure patterns are illustrated using isobars. These lines connect points of equal atmospheric pressure on a map, helping to visualize pressure systems. Analyzing these isobars allows meteorologists to identify high and low-pressure areas, the locations of weather fronts, and potential storm paths. Isobars are critical for understanding weather patterns, as they convey information about wind speed and direction; winds flow from high-pressure areas toward low-pressure areas and are influenced by the spacing of the isobars—closely spaced lines indicate stronger winds. The other terms listed refer to different concepts in meteorology. Contour lines are often associated with topographical maps that depict elevation changes, isotherms represent lines of equal temperature, and isohyets indicate lines of equal precipitation. Therefore, isobars are correctly identified as the lines depicting sea level pressure patterns on a Surface Analysis Chart.
