Abstract
Rotating convection under both strong thermal forcing and strong rotation serves as an essential baseline for understanding geophysical and astrophysical flows. Here, heat transfer and temperature profile measurements in rotating convection with unprecedentedly strong thermal forcing and rotational influence are reported. Changes in the vertical temperature gradient are found to separate various flow phenomenologies. Additionally, a novel flow regime is described where the temperature gradient scaling with thermal forcing and the bounding parameter ranges distinguish it from previously known regimes.
