Interpreting seasonal and interannual Hadley cell descending edge migrations via the cell-mean Rossby number
Spencer A Hill, Simona Bordoni, Jonathan L Mitchell +1
The poleward extent of Earth's zonal-mean Hadley cells varies across seasons and years, which would be nice to capture in a simple theory. A plausible, albeit diagnostic, candidate…
A simple model for the emergence of relaxation-oscillator convection
Francisco E. Spaulding-Astudillo, Jonathan L. Mitchell
Earth's tropics are characterized by quasi-steady precipitation with small oscillations about a mean value, which has led to the hypothesis that moist convection is in a state of q…
Toward a unified theory for the Hadley cell descending and ascending edges
Spencer A. Hill, Simona Bordoni, Jonathan L. Mitchell
We present theories for the latitudinal extents of both Hadley cells throughout the annual cycle by combining our recent scaling for the ascending edge latitude (Hill et al. 2021)…
Solsticial Hadley Cell ascending edge theory from supercriticality
Spencer A. Hill, Simona Bordoni, Jonathan L. Mitchell
How far the Hadley circulation's ascending branch extends into the summer hemisphere is a fundamental but incompletely understood characteristic of Earth's climate. Here, we presen…
Constraints from invariant subtropical vertical velocities on the scalings of Hadley cell strength and downdraft width with rotation rate
Jonathan L. Mitchell, Spencer A. Hill
Weak-temperature-gradient influences from the tropics and quasigeostrophic influences from the extratropics plausibly constrain the subtropical-mean static stability in terrestrial…
Simulating Venus' Cloud Level Dynamics Using a Middle Atmosphere General Circulation Model
Helen F. Parish, Jonathan L. Mitchell
The atmosphere of Venus is characterized by strong superrotation, in which the wind velocities at cloud heights are around 60 times faster than the surface rotation rate. The reaso…
