The second Dynamics and Chemistry of Marine Stratocumulus (DYCOMS-II) field study is described. The field program consisted of nine flights in marine stratocumulus West-Southwest of San Diego California. The objective of the program was to better understand the physics and dynamics of marine stratocumulus. Toward this end special flight strategies,(More)
Cloudy air, containing small (∅ 14 μm) water droplets, undergoes mixing with the unsaturated environment inside the cloud chamber in the process resembling smallest scales of entrainment and mixing in real clouds. Particle Image Velocimetry (PIV) applied to images from the chamber interior is used to investigate dynamics of the process in scales from 1.2 mm(More)

Small-scale mixing between cloudy air and unsaturated clear air is investigated in numerical simulations and in a laboratory cloud chamber. Despite substantial differences in physical conditions and some differences in resolved scales of motion, results of both studies indicate that small-scale turbulence generated through cloud–clear air interfacial mixing(More)
1. ABSTRACT Astounded at the regularity of convective structures observed in simulations of mesoscale flow past realistic topography, we take a deeper look into numerics of a classical problem of flow over a heated plate [1]. We find that solutions are sensitive to viscosity, which is either incorporated a priori or effectively realized in numerical models.(More)
A method of retrieval of the aerosol particle size distribution (APSD) from multiwavelength lidar signals is presented. Assumed distribution (usually a bimodal combination of lognormal functions) with a few free parameters is directly substituted into the lidar equations. The minimization technique allows one to find the parameters that provide the best fit(More)
