What is Pressure gradient?
In [[atmosphere|atmospheric]] [[science]]s ([[meteorology]], [[climatology]] and related fields), the '''pressure gradient''' (typically of [[air]], more generally of any [[fluid]]) is a physical quantity that describes in which direction and at what rate the [[pressure]] changes the most rapidly around a particular location. The pressure gradient is a dimensional quantity expressed in [[Units of measurement|units]] of pressure per unit length. The [[International System of Units|SI]] unit is [[pascal (unit)|pascal]] per [[metre]] (Pa/m). ==Other websites== * [http://www.grida.no/climate/ipcc_tar/wg1/index.htm IPCC Third Assessment Report] {{science-stub}} [[Category:Atmosphere]]
