(meteorology)
The force due to differences of pressure within the atmosphere; it usually refers only to the horizontal component of the force. Also known as pressure force.

82) Since the pressure-gradient force is not anti-symmetric, linear momentum is not preserved in the original MPS method.
Linear momentum is exactly conserved in ISPH method, because both pressure-gradient force and viscous force are anti-symmetric.
This is most likely to happen if the angular momentum-rich air possesses only weak negative buoyancy and is subjected to an upward-directed dynamic pressure-gradient force (in effect, upward-directed "suction").
