Earth air pressure mbar
WebDec 3, 2013 · Pressure is usually around 1000hPa, and at sea level, it rarely gets lower than 950hPa or higher than 1050 hPa. So high pressure gives fine, dry weather – warm in summer (remember how glorious July was!) but with cold nights in winter. But on the other hand, low pressure brings clouds, rain and strong winds. The first barometers used a J ... Webatmospheric pressure, also called barometric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above …
