noun

  1. Meteorology. a line drawn on a weather map or chart that connects points at which the barometric pressure is the same.
  2. Also i·so·bare [ahy-suh-bair] /ˈaɪ səˌbɛər/. Physics, Chemistry. one of two or more atoms having equal atomic weights but different atomic numbers.

noun

  1. a line on a map connecting places of equal atmospheric pressure, usually reduced to sea level for purposes of comparison, at a given time or period
  2. physics any of two or more atoms that have the same mass number but different atomic numberstin-115 and indium-115 are isobars Compare isotope
n.

1864, coined from Greek isos “equal” (see iso-) + baros “weight,” from barys “heavy” (see grave (adj.)). Line connecting places with the same barometric pressure at the same time.

n.

  1. Any of two or more kinds of atoms having the same atomic mass but different atomic numbers.
  2. A line on a weather map connecting points of equal atmospheric pressure.

  1. A line drawn on a weather map connecting places having the same atmospheric pressure. The distance between isobars indicates the barometric gradient (the degree of change in atmospheric pressure) across the region shown on the map. When the lines are close together, a strong pressure gradient is indicated, creating conditions for strong winds. When the lines are far apart, a weak pressure gradient is indicated and calm weather is forecast.
