This research is supported by NRL Base Program PE 0601153N. Dr. A. Reinecke helped us with the implementation of the selective monotonic advection scheme. The authors also want to thank Drs. H. Wang and G. Feingold for the helpful discussions about the two-moment cloud microphysics. The primary sponsor of VOCALS is the U.S. National Science Foundation. The simulations were performed using the LES component of the Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS-LES) developed by the U.S. Naval Research Laboratory. Computational resources were supported by a grant of HPC time from the Department of Defense Major Shared Resource Centers.
