The Role of Bottom Thermal Forcing on Modulating Baroclinic Instability in a Jupiter GCM Open
The atmospheric circulation of Jupiter is shaped by a complex interplay between deep internal processes and cloud-level dynamics. Numerical simulations and observational analyses have suggested that Jupiter’s mid-latitude jets are strongly…
