  We investigate the predictability aspects of rotating turbulent flows through
extensive numerical simulations of a shell model of rotating turbulence. In
particular, we measure the large-scale predictability time and find that it
increases with rotation rate to satisfy a power law in Rossby number with a
scaling exponent of $-2/3$. Intriguingly, we find that before entering the
algebraic growth stage, the error dynamics freezes for a time period determined
by the finite Rossby number. We further analyse the scale dependence of the
predictability time and observe that it tends to become scale independent in
the Zeman range as the Rossby number decreases. Finally, we compute the finite
size Lyapunov exponent and validate the dimensional prediction of its scaling
$\sim\delta^{-1}$ for large $\delta$ of the order of velocities in the Zeman
range for small Rossby numbers.
