both (liquid water) pressure gradient ( http://www.glossary.oilfield.slb.com/Display.cfm?Term=pressure%20gradient ) and geopressure gradient ( http://www.glossary.oilfield.slb.com/Display.cfm?Term=geopressure%20gradient ) could be added here.

Geopressure gradient accompanies the Geothermal gradient.

It is more intuitively fitting to talk about volumetric forces instead of pressure gradients. The unit would be Newton per cubic meter, N/m³. This figure tells the net force on a volume of a medium. Pa/m doesn't say much about the physics. Neither can I understand why this article is specific to meteorology. Pressure gradients can exist in any medium. Even among the few particles in interstellar space. Davidjonsson (talk) 17:28, 29 March 2008 (UTC)
