Wind shear and the role of eddy vapor transport in driving water convection on Jupiter
Ramanakumar Sankar, Michael H Wong, Csaba Palotai +1
Recent observations of convection in the jovian atmosphere have demonstrated that convection is strongly concentrated at specific locations on planet. For instance, observations of…
Atmospheric Science Questions for a Uranian Probe
Emma K. Dahl, Naomi Rowe-Gurney, Glenn S. Orton +5
The Ice Giants represent a unique and relatively poorly characterized class of planets that have been largely unexplored since the brief Voyager 2 flyby in the late 1980's. Uranus…
A new convective parameterization applied to Jupiter: implications for water abundance near the N region
Ramanakumar Sankar, Csaba Palotai
Jupiter's atmosphere features a variety of clouds that are formed from the interplay of chemistry and atmospheric dynamics, from the deep red color of the Great Red Spot to the hig…
The aftermath of convective events near Jupiter's fastest prograde jet: implications for clouds, dynamics and vertical wind shear
Ramanakumar Sankar, Chloe Klare, Csaba Palotai
The N jet borders the North Tropical Belt and North Tropical Zone, and is the fastest prograde jet on Jupiter, reaching speeds above m/s. In this region, observa…
Ice Giant Atmospheric Science
Emma K. Dahl, Shawn Brueshaber, Richard Cosentino +24
This white paper, written in support of NASA's 2023-2032 Planetary Decadal Survey, outlines 10 major questions that focus on the origin, evolution, and current processes that shape…
EPIC Simulations of Neptune's Dark Spots Using an Active Cloud Microphysical Model
Nathan Hadland, Ramanakumar Sankar, Raymond Paul LeBeau +1
The Great Dark Spot (GDS-89) observed by Voyager 2 was the first of several large-scale vortices observed on Neptune, the most recent of which was observed in 2018 in the northern…
Fragmentation modelling of the August 2019 impact on Jupiter
Ramanakumar Sankar, Csaba Palotai, Ricardo Hueso +3
On 7th August 2019, an impact flash lasting s was observed on Jupiter. The video of this event was analysed to obtain the lightcurve and determine the energy release and ini…
Analysis of June 2, 2016 bolide event
Csaba Palotai, Ramanakumar Sankar, Dwayne L. Free +3
On June 2, 2016 at 10h56m UTC, a magnitude superbolide was observed over Arizona. Fragments were located a few days later and the meteorites were given the name Dis…
Numerical Modeling of the 2009 Impact Event on Jupiter
Jarrad W. T. Pond, Csaba Palotai, Travis Gabriel +3
We have investigated the 2009 July impact event on Jupiter using the ZEUS-MP 2 three-dimensional hydrodynamics code. We studied the impact itself and the following plume developmen…
Plume Development of the Shoemaker-Levy 9 Comet Impact
Csaba Palotai, Donald G. Korycansky, Joseph Harrington +2
We have studied plume formation after a Jovian comet impact using the ZEUS-MP 2 hydrodynamics code. The three-dimensional models followed objects with 500, 750, and 1000 meter diam…
