Modulation of the tropical meridional circulation by the Madden-Julian Oscillation
Wuqiushi Yao, Or Hadas, Yohai Kaspi
The Hadley circulation is Earth's dominant tropical overturning circulation, regulating atmospheric energy transport, tropical rainfall, and subtropical aridity. Although its varia…
Juno Microwave Radiometer Observations Reveal A Warmer Polar Atmosphere on Jupiter
Jiheng Hu, Cheng Li, Sushil K. Atreya +15
The intriguing circumpolar cyclone pattern at Jupiter's poles raises fundamental questions about how these systems are organized vertically and, further, how the planet's internal…
Geant4-IcyMoons: Simulating Electron Interaction Physics in Irradiated Astrophysical Ices
Gideon Yoffe, Jacques Pienaar, Ioanna Kyriakou +4
Energetic particles continuously process water ice across astrophysical and planetary environments, from interstellar clouds and comets to icy planetary surfaces. Interpreting the…
Molecular diversity as a biosignature
Gideon Yoffe, Fabian Klenner, Barak Sober +2
The search for life in the Solar System hinges on data from planetary missions. Detecting biosignatures based on molecular identity, isotopic composition, or chiral excess requires…
Predictability of Storms in an Idealized Climate Revealed by Machine Learning
Wuqiushi Yao, Or Hadas, Yohai Kaspi
The midlatitude climate and weather are shaped by storms, yet the factors governing their predictability remain insufficiently understood. Here, we use a Convolutional Neural Netwo…
From gas to ice giants: A unified mechanism for equatorial jets
Keren Duer-Milner, Nimrod Gavriel, Eli Galanti +2
The equatorial jets dominating the dynamics of the Jovian planets exhibit two distinct types of zonal flows: strongly eastward in the gas giants (superrotation) and strongly westwa…
Fluorescent Biomolecules Detectable in Near-Surface Ice on Europa
Gideon Yoffe, Keren Duer, Tom Andre Nordheim +2
Europa, Jupiter's second Galilean moon, is believed to host a subsurface ocean in contact with a rocky mantle, where hydrothermal activity may drive the synthesis of organic molecu…
Quantifying the Influence of Climate on Storm Activity Using Machine Learning
Or Hadas, Yohai Kaspi
Extratropical storms shape midlatitude weather and vary due to the slowly evolving climate and the rapid changes in synoptic conditions. While the influence of each factor has been…
Dynamical constraints on the vertical structure of Jupiter's polar cyclones
Nimrod Gavriel, Yohai Kaspi
Jupiter's poles feature striking polygons of cyclones that drift westward over time, a motion governed by beta-drift (vortex motion caused by the latitudinal variation of the Corio…
Uranus Study Report: KISS
Mark Hofstadter, Ravit Helled, David J. Stevenson +27
Determining the internal structure of Uranus is a key objective for planetary science. Knowledge of Uranus's bulk composition and the distribution of elements is crucial to underst…
Depth Dependent Dynamics Explain the Equatorial Jet Difference Between Jupiter and Saturn
Keren Duer, Eli Galanti, Yohai Kaspi
Jupiter's equatorial eastward zonal flows reach wind velocities of ~100 m/s, while on Saturn they are three times as strong and extend about twice as wide in latitude, despite the…
NeuralCMS: A deep learning approach to study Jupiter's interior
Maayan Ziv, Eli Galanti, Amir Sheffer +3
NASA's Juno mission provided exquisite measurements of Jupiter's gravity field that together with the Galileo entry probe atmospheric measurements constrains the interior structure…
A Lagrangian Perspective on the Growth of Midlatitude Storms
Or Hadas, Yohai Kaspi
Extratropical storms dominate midlatitude climate and weather and are known to grow baroclinicaly and decay barotropicaly. Traditionally, quantitative climatic measures of storm gr…
Gas Giant Simulations of Eddy-Driven Jets Accompanied by Deep Meridional Circulation
Keren Duer, Eli Galanti, Yohai Kaspi
Jupiter's atmosphere comprises several dynamical regimes: the equatorial eastward flows and surrounding retrograde jets; the midlatitudes, with the eddy-driven, alternating jet-str…
The westward drift of Jupiter's polar cyclones explained by a center-of-mass approach
Nimrod Gavriel, Yohai Kaspi
The first orbits around Jupiter of the Juno spacecraft in 2016 revealed a symmetric structure of multiple cyclones that remained stable over the next five years. Trajectories of in…
The Shape of Jupiter and Saturn Based on Atmospheric Dynamics, Radio Occultations and Gravity Measurements
Eli Galanti, Yohai Kaspi, Tristan Guillot
The shape of the two gas giants, Jupiter and Saturn, is determined primarily by their rotation rate, and interior density distribution. It is also affected by their zonal winds, ca…
