| Aug 31, 2022 at 13:16 | comment | added | vengaq | Thank you for your answer. So, just to confirm, as the question says, imagine the Earth as a single planet with no Sun (so no influence by the Sun's heat), no moon (so no tides) and no planetary internal hot core (so no influence by the heat from Earth's internal core). Then assume that somehow water is still liquid and air in its gas form, then, just by Earth's rotation, would there be any Rossby and Kelvin waves? And would there be any wind (I suppose the answer is affirmative as there would be low level jet currents as you mentioned, but just to confirm)? @BarocliniCplusplus | |
