## Section 5.4 Centrifugal force

The centrifugal force is caused by centripetal acceleration (toward the center of the rotation); for wind the centrifugal force points outward from the center of rotation (that is, it is the tendency of wind to want to travel in a straight line)

\begin{equation*}
$CENT=\frac{V^2}{R}$
\end{equation*}

where \(R\) is positive for cyclonic flow and negative for anticyclonic flow: works against PGF around lows and with PGF around highs; this force also gets very strong for small turning radii.
