Quizplus · Accepted Answer

Contour lines are drawn on 500 millibar charts to show changes in altitude that correspond to changes in pressure. These lines help to identify areas of high and low pressure and can be used to analyze weather patterns at the 500 millibar level. Isobars represent changes in pressure only and are not relevant to altitude. Isotherms represent changes in temperature, and isotachs represent changes in wind speed. Isofiles are not a common term used in meteorology.
