Geophysical studies and angular momentum budgets confirm that the Earth's atmosphere rotates synchronously with the planet overall, driven and coupled largely through surface friction and mountain torques.

The analysis

The retrieved papers provide theoretical and modeling backing regarding the planetary boundary layer, frictional torques, and angular momentum exchange between the solid Earth and its atmosphere. These mechanisms explain how the atmosphere maintains its overall rotational coupling with the planet.

Angular momentum exchange between atmosphere and Earth

Recorded source metadata

Jean O. Dickey. Angular momentum exchange between atmosphere and Earth. 1993. https://doi.org/10.1029/93eo00219

Examines angular momentum exchange between the atmosphere and Earth, noting that without such interactions and internal torques the entire planet and its fluid layers would rotate synchronously.
