The 7 Types of Weather in a High Pressure System

Jul 03, 2019· A high-pressure zone can have a reading of 960 millibars (mb). And a low-pressure zone can have a reading of 980 millibars for example. The 980 mb is clearly a greater pressure than the 960 mb, but it is still labeled a low when stated in comparison to the surrounding air.

Convert Pressure, Millibar

Millibar (Metric), pressure. The bar (symbol bar) and the millibar (symbol mbar, also mb) are units of pressure. They are not SI units, but accepted (although discouraged) for use with the SI. The bar is still widely used in descriptions of pressure because it is about the same as atmospheric pressure.
