1. (meteorology) A line drawn on a map or chart connecting places of equal or constant pressure.

使用する際の注意点

• (meteorology):

  In meteorology, the term isobar most often refers to a line drawn through connected points of equal atmospheric pressure on a given reference surface — such as a constant height surface (notably mean-sea-level on surface charts), the vertical plane of a synoptic cross section, or a layer of the air unaffected by surface heating or cooling. The pattern of isobars has always been a main feature of surface chart analysis. (See Surface weather analysis on Wikipedia.Wikipedia ) It was standard procedure to draw isobars at 3-millibar intervals until the recent advent of constant pressure charts for upper-air analysis brought about the use of 4-millibar intervals to simplify the conversion from surface isobars to 1,000-millibar contour lines.
