What is Isobar?
[[File:Isobaren bei Orkan.svg|thumb|Isobar lines, showing a [[hurricane]] over the [[British Isles]].]] In [[meteorology]], an '''isobar''' is a line on a [[map]] that connects areas with the same [[atmospheric pressure]]. [[Wind]] is generally [[perpendicular]] to isobars. When looking at the difference in pressure, it is also possible to estimate wind direction and speed. The first person to use isobars was [[Alexander Buchan]] (1829-1907). {{weather-stub}} [[Category:Meteorology]]
