Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a broad area (like the U.S.), and they can tell us how intense the system may be.
Isotherms help to visualize and interpret the horizontal temperature distribution of an area by showing patterns of temperature on a weather or oceanography map. Constructing a map of isotherms is an elementary step in temperature data analysis, and the process in general is called contouring.
