What Is Isobar?
A line on a weather map connecting places with equal air pressure. Tightly packed isobars mean strong wind. In technical terms: A line of constant pressure on a constant-height or sea-level surface analysis, usually at 4 hPa intervals in the US; the spacing indicates the pressure gradient and hence geostrophic wind speed.
