Section5.3Coriolis force

The Coriolis force is an acceleration produced by the Earth's rotation:

• produces a right-hand turn in Northern Hemisphere

• produces a left-hand turn in Southern Hemisphere

This is also the source of how we describe cyclonic rotation (counter-clockwise around a low) and anticyclonic rotation (clockwise around a high)

\begin{equation*} CF = 2fV \end{equation*}

where $$V$$ is the wind speed and $$f=2\Omega sin \phi\text{;}$$ the Coriolis force increases with wind speed and increases with increasing latitude.
