Nonlinear simulations of Jupiter's 5-micron hot spots

Large-scale nonlinear simulations of Jupiter's 5-micron hot spots produce L ong-lived coherent structures that cause subsidence in local regions, expla ining the Low cloudiness and the dryness measured by the Galileo probe insi de a hot spot. Like observed hot spots, the simulated coherent structures a re equatorially confined, have periodic spacing, propagate west relative to the flow, are generally confined to one hemisphere, and have an anticyclon ic gyre on their equatorward side, The southern edge of the simulated hot s pots develops vertical shear of up to 70 meters per second in the eastward wind, which can explain the results of the Galileo probe Doppler wind exper iment.
