Usage notes
* (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)) Until recently it was standard procedure to draw isobars at 3-millibar intervals. However, the advent of constant pressure charts for upper-air analysis has brought about the use of ' 4-millibar intervals to simplify the conversion from surface isobars to 1,000-millibar contour lines.
