How is air pressure labeled on a weather map
Webline has the same air pressure (barometric). Each isobar separates areas of higher pressure from areas of lower pressure. The Figure 1A-1 surface map shows air pressure in whole millibars (mb) at weather stations. (A milli-bar is the traditional unit for atmospheric pressure. 1 mb = 100 Pascals (Pa) and 1 Pa = 1 (N/m2).) WebThey show areas of convergence, divergence and pressure circulation. Thickness lines Same as an isohypse except they represent the distance from one pressure level to a selected pressure level (usually 1000 to 500 mb thickness). They are used to forecast snow, cold air advection, and warm air advection.

Historically, older units have been used for pressure, and are sometimes still used on marine weather charts: millibar (mb) and hectoPascals (hPa). It is easy to convert between these units: 10 mb = 10 hPa = 1 kPa. Average air pressure is around 101.3 kPa.
