Fig. S3.

Numerically computed probability density function (blue circles) for the longitudinal (Upper Row) and transverse (Lower Row) velocity increments for three different separations: $L/2$ (Left Column), $L/8$ (Center Column), and $L/16$ (Right Column), where L denotes the box size of $10\pi \ell$. Here the Ekman parameter equals $\alpha \tau =3$. The red line gives the closest fit of a Gauss distribution. The statistics of the velocity field at large scales are again very close to Gaussian.
