بسامد ِ کوریولیس basâmad-e Coriolis
*Fr.: fréquence de Coriolis*
A quantity defined as
*f* = 2ω.sinθ, where ω is the Earth's
→ *angular velocity*, 2π/*T*,
*T* is the rotation period of the Earth (→ *sidereal day*),
and θ is the → *latitude*.
Also called the → *Coriolis parameter*.
This frequency occurs often in oceanographic studies. If an
→ *iceberg* is floating
in a frictionless sea, and is given a push and allowed to move freely, it will travel in a
circle of radius *U/f*, where *U* is the initial speed imparted by the push.
This circle is called an *inertial circle*. → *Coriolis effect*; → *frequency*. |
