Euler force

The Euler force is a fictitious force found in rotating frames of reference. It depends on the angular acceleration of the rotating reference frame and the position of a particle in that frame. It can be described mathematically as:

${\vec {F}}=-m{\vec {\dot {\omega }}}\times {\vec {r}}$

where ${\vec {\dot {\omega }}}$ is the angular acceleration and ${\vec {r}}$ is the position vector. As the angular acceleration of the earth is very small it can normally be neglected on Earth.
