●Recently, researchers at the Shanghai Observatory of the Chinese Academy of Sciences revealed the new mechanism of thermal convection movement within a rapidly rotating celestial body for the first time through theoretical deduction. Related research results were published in the fluid mechanics journal "Evaluation of Fluid Theory" on the 27th. This result systematically studies the different rotational rates of celestial bodies on the occurrence of thermal convection to judge how the non-spherical shape of celestial bodies affects thermal convection motion and helps to study and understand the convection process in these planets.
