Dramatic Change in Jupiter ’ s Great Red Spot
Introduction: Jupiter’s Great Red Spot (GRS) is one of its most distinct and enduring features, having been continuously observed since the 1800’s. It currently spans the smallest latitude and longitude size ever recorded. Here we show analyses of 2014 Hubble spectral imaging data to study the color, structure and internal dynamics of this long-live storm. Physical Dimensions: The GRS’s red edg...
متن کاملJupiter’s Red Spot
The Great Red Spot, the largest of Jupiter’s long lived, approximately two dimensional, coherent vortices, measures approximately 26, 000 × 13, 000 km in the horizontal direction and is assumed to be roughly 20-40 km deep. Previous studies, including laboratory experiments and numerical simulations, suggest that many of the important characteristics of Jovian vortices can be explained through q...
متن کاملOn the interaction of Jupiter’s Great Red Spot and zonal jet streams
Jupiter’s Great Red Spot (GRS) has been observed in sufficient detail that we can use it to determine properties of the jovian atmosphere that cannot otherwise be found. These properties include: the potential vorticity of the GRS and its neighboring zonal jet streams, the shear imposed on the GRS by the jet streams, and the vertical entropy gradient (i.e., Rossby deformation radius). We show t...
متن کاملFlow Fields within Jupiter's Great Red Spot and White Oval BC
Using sequences of Voyager 1 high-resolution images of Jupiter's Great Red Spot (GRS) and White Oval BC we map the flow fields within the GRS and Oval BC. We compute relative vorticity within these features as a function of semi-major axis length and position angle in a coordinate system consisting of concentric ellipses of equal eccentricity. Both the velocity and the relative vorticity profil...
متن کاملEmergence of intense jets and Jupiter Great Red Spot as maximum entropy structures
We explain the emergence and robustness of intense jets in highly turbulent planetary atmospheres, like on Jupiter, by a general approach of statistical mechanics of potential vorticity patches. The idea is that potential vorticity mixing leads to the formation of a steady organized coarse grained flow, corresponding to the statistical equilibrium state. Our starting point is the quasi-geostrop...
