isobar
Equal pressure curve
An isobar is a line on a weather map connecting points of equal atmospheric pressure.
Meteorologists use isobars to visualize pressure systems—closely spaced isobars indicate steep pressure gradients and strong winds.
In physics and chemistry, isobars are atoms of different elements having the same mass number but different atomic numbers.
