= Solution
In a frame rotating with <angular velocity> $\boldsymbol\Omega$, a particle of relative <velocity> $\mathbf v$ experiences the <Coriolis force>
$$
\boxed{\mathbf F_C=-2m\boldsymbol\Omega\times\mathbf v.}
$$
For nearly horizontal atmospheric motion, the relevant vertical <rotation> component is $\Omega\sin\ell$, with latitude $\ell$. In the northern hemisphere the horizontal deflection is to the right of the motion. A low-pressure center produces an inward pressure-gradient force; an anticlockwise circulation has an outward <Coriolis force> to oppose it. A high-pressure center instead supports clockwise circulation, with inward <Coriolis force> opposing the outward pressure-gradient force.
The sense reverses in the southern hemisphere. There, anticlockwise circulation is anticyclonic and corresponds to high <atmospheric pressure>. Hence
$$
\boxed{\text{Earth northern hemisphere: low anticlockwise, high clockwise; Jupiter's Great Red Spot: high pressure.}}
$$
This is the large-scale rotating-fluid interpretation; <friction>, centrifugal <acceleration> and departures from ideal balance modify actual wind profiles. NASA's description independently identifies the southern, counterclockwise <Great Red Spot> as a high-pressure system.<The Great Red Spot: An Ancient Storm in Jupiter's Atmosphere by National Aeronautics and Space Administration>[Description comparing the southern-hemisphere counterclockwise Great Red Spot with low-pressure terrestrial hurricanes]{ref}
