Flow in the absence of external forces; in meteorology, frictionless flow in a geopotential surface in which there is no pressure gradient. The inertial period (the reciprocal of inertial frequency) is just one-half pendulum day. …

What is inertial wind?

The inertial wind is derived from the balance of the following forces in the n equation of motion: The centrifugal force: The coriolis force: Inertial flows are also known as inertial oscillations, since air parcels under the influence of inertial balance follow circular paths in an anti-cyclonic manner.

What is meant by inertial forces?

inertial force, also called Fictitious Force, any force invoked by an observer to maintain the validity of Isaac Newton’s second law of motion in a reference frame that is rotating or otherwise accelerating at a constant rate.
