Investigate how the general circulation and equatorial superrotation will change with the atmospheric shortwave absorption.
As the meridional circulation turns from thermally indirect to thermally direct with an increasing insolation, upper air zonal wind accelerates westward and cloud fraction drops.
The stratosphere is much wetter under high obliquity, allowing water vapor evaporated from the surface ocean to be detected from space.
Why are high obliquity aquaplanets always warmer than low obliquity equivalents?
The bottom-amplified baroclinic eddies and thermally-indirect Hadley cell in a world with a reversed meridional temperature gradient, as expected under high obliquity.
MJO-like forcings at different longitudinal locations drive the SSWs to different fates: interaction with the mid-latitude jet zonal asymmetry. read more…
Background zonal asymmetry allows MJO to either enhance or suppress the SSWs
Doubling of SSW occurrence and significant warmer & weaker polar vortex due to stronger MJO as expected in a warmer climate.
