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…

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…

Axisymmetric constraints on cross-equatorial Hadley cell extent
Spencer Hill, Simona Bordoni, Jonathan L. Mitchell
We consider the relevance of known constraints from each of Hide's theorem, the angular momentum conserving (AMC) model, and the equal-area model on the extent of cross-equatorial…
