  • Large-eddy simulation of precipitating cumulus clouds

    Simulation of cumulus clouds under conditions observed during the Rain in Cumulus over the Ocean (RICO) field campaign. Within the gray volume, there is cloud liquid water, simulated with the PyCLES code developed by Kyle Pressel et al. Blue colors indicate rain. The simulation uses 5th-order weighted essentially non-oscillatory (WENO) schemes for discretization of all fluxes (of momentum, entropy, and total water), at a resolution of 50 m in the horizontal and 40 m in the vertical.

  • Large-eddy simulation of stratocumulus clouds

    Simulation of stratocumulus clouds in the Dynamics and Chemistry of Marine Stratocumulus (DYCOMS) field study. Colors show the liquid water path (amount of liquid water in atmospheric columns) simulated with PyCLES. The simulation uses weighted essentially non-oscillatory (WENO) schemes for discretization of all fluxes (of momentum, entropy, and total water), which leads to improved fidelity of simulations already at relative low resolution.
