On a weather map, isobars are contour lines that connect different locations or points with the same constant pressure, while isotherms are also contour lines, which specify locations that are at the same constant temper... More »

Isobars are depicted on a weather map to show where the areas of equal or constant pressure are located. The closer isobars are to each other, the higher the winds will be in that same area. The farther apart the isobars... More »
