Section 5.3 Coriolis 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.
