Superrotation in planetary atmospheres
WebMay 12, 2024 · Exploring diverse planetary atmospheres requires modeling tools that are both accurate and flexible. Here, we develop a three-dimensional general circulation model (3D GCM) that for the first time uses a line-by-line approach to describe the radiative transfer. We validate our GCM by comparing with published results done by different 1D … WebThe traditional view of such a planet consists of the outer atmosphere laying on top of a condensed layer of oxide and silicates — solid like the crust of a terrestrial planet, or liquid …

WebJul 28, 2024 · It rotates about 60 times faster (once every 4 terrestrial days) than the underlying surface (243 terrestrial days) — a phenomenon known as superrotation. Planetary researchers do not yet fully understand its origin and motor, but are working on an answer to this puzzle. Web2 days ago · We present a parameterization for the eddy diffusion profile of gas giant exoplanets based on physical phenomena and we explore how the parameterized eddy profile impacts the chemical composition, the thermal structure, the haze microphysics, and the transit spectra of 8 hot-Jupiters. Our eddy parameterization depends on the planetary …
