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 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...
متن کاملGeneralized thermodynamics and Fokker - Planck equations . Applications to stellar dynamics , two - dimensional turbulence and Jupiter ’ s great red spot
We introduce a new set of generalized Fokker-Planck equations that conserve energy and mass and increase a generalized entropy until a maximum entropy state is reached. The concept of generalized entropies is rigorously justified for continuous Hamiltonian systems undergoing violent relaxation. Tsallis entropies are just a special case of this generalized thermodynamics. Application of these re...
متن کاملPhase separation of bacterial colonies in a limit of high degradation . Analogy with Jupiter ’ s great red spot
We discuss the structure of the equilibrium states of a regularized Keller-Segel model describing the chemotaxis of bacterial populations. We consider the limit of high degradation of the secreted chemical where analytical results can be obtained. Below a critical effective temperature, the system experiences a second order phase transition from a homogeneous phase to an inhomogeneous phase for...
متن کاملA comparison of the structure of the aerosol layers in the great red spot of Jupiter and its surroundings before and after the 1993 SEB disturbance
The structure of the aerosol layers in the Great Red Spot (GRS) of Jupiter is investigated from high-quality CCD ground-based observations. The observation of the feature was made at a variety of wavelengths at UV through the near-infrared and at different observational geometries as the large oval rotated from the central meridian to the limb, and at different times, specifically before and af...
