Large-eddy simulation of the atmosphere in a (tropical) radiative-convective equilibrium (RCE) experiment.

The domain is 38 by 38 km in the horizontal, 19 km in the vertical. Horizontal resolution is 100 meters, vertical is 30 m at the lowest levels and coarser higher up.

Simulation shows clouds (using a liquid water isosurface), rain water (volumetric rendering) and a horizontal equivalent potential temperature (theta_e) cross section at z=15 m.

3 hours of data is visualized in this animation. The full simulations, which are run for 20-30 days, are part of my thesis work on the role of surface heat exchange in RCE. The research is done in the context of RCEMIP: myweb.fsu.edu/awing/rcemip.html

Rendered using ParaView, simulation run using MicroHH (microhh.org).
