The Coriolis frequency ƒ, also called the Coriolis parameter or Coriolis coefficient,[1] is equal to twice the rotation rate Ω of the Earth multiplied by the sine of the latitude .

The rotation rate of the Earth (Ω = 7.2921 × 10−5 rad/s) can be calculated as 2π / T radians per second, where T is the rotation period of the Earth which is one sidereal day (23 h 56 min 4.1 s).[2] In the midlatitudes, the typical value for is about 10−4 rad/s. Inertial oscillations on the surface of the Earth have this frequency. These oscillations are the result of the Coriolis effect.
