科里奥利频率（英语：Coriolis frequency） ƒ，也称做科里奥利参数或科里奥利系数，是地球自转角速度率Ω的2倍乘以纬度φ的正弦

地球自转速度 Ω = 7.2921 × 10 rad/s)可以表示为2π / T rad/s，其中T 为地球的旋转周期，也就是一个恒星日（23 小时 56 分 4.1 秒）。科里奥利频率是地球表面惯性波的频率，振动也是科里奥利力产生的结果。

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

The rotation rate of the Earth (Ω = 7.2921 × 10 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 hr 56 m 4.1 s). In the midlatitudes, the typical value for is about 10 rad/s. Inertial oscillations on the surface of the earth have this frequency. These oscillations are the result of the Coriolis effect.
