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).) WebThe inner-most closed isobar is 996 millibars (it's unlabeled, but it's inside of the 1000 millibar isobar and values are decreasing toward the center of the low), so the pressure must be less than 996 millibars. However, there's no 992 millibar isobar drawn, so the pressure must be greater than 992 millibars.

WebAir pressure is the weight of the air over the ground and its unit is the kiloPascal (kPa). 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. WebAbove every square inch on the surface of the Earth is 14.7 pounds of air.
