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)
The so called “warm rain initiation problem” attracts attention of cloud physicists, turbulence researchers, engineers and meteorologists. It is still uncertain which mechanism is responsible for the formation of drizzle and rain (precipitation) drops. Papers concerning the impact of high-Reynolds-number turbulence on spatial distribution of cloud droplets,(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)
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)
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. In(More)
In this report, experimentsmimicking some aspects of cloud-clear-air mixing in a laboratory chamber are discussed. A saturated plume containing small droplets of water (a surrogate of an atmospheric cloud) is mixedwith unsaturated environmental air in order to study effect of evaporative cooling at the interfaces between cloudy and clear air filaments on(More)
Interaction between small-scale turbulence and cloud particles is a key issue in warm rain formation mechanism, which is an important meteorological and climatological challenge [1],[2]. We investigate this interaction observing motion of cloud droplets in a glass walled chamber 1m deep, 1m wide and 1.8m high [3]. The second smaller chamber, placed above(More)
