Jupiter's Great Red Spot threatened along 2019 by strong interactions with close anticyclones
Abstract
Throughout 2019, Jupiter's Great Red Spot (GRS) strongly interacted along its periphery with successive anticyclones that ripped off and detached part of the red aerosols from its top haze and at the same time distorted the shape of the GRS itself. The GRS survived and recovered from these attacks, as it has been seen on previous occasions (Sánchez-Lavega et al., Icarus, 136, 14-26.1998; Sánchez-Lavega, JGR, 118, 2537-2557.2013), but with significant changes in its surroundings. We present an analysis of these interactions based on images taken with ground-based telescopes with a high temporal sampling and coverage, and with the high-resolution images obtained with JunoCam/JUNO along different perijoves. We also present numerical models of the dynamics of these interactions and of the structure and properties of the aerosols on the cloud top of the GRS.
