Abstract: A new algorithm was developed to classify populations of binary (black and white) images of cloud particles collected with Particle Measuring Systems (PMS) Optical Array Probes (OAPA). The algorithm classifies images into ...

Abstract: The finescale, spatial inhomogeneity of cloud-droplet concentration in stratiform clouds is studied using FSSP-100 data with 10-m or better resolution from 1700 km of cloud penetrations between +5° and ?20°C. The data are ...

Abstract: A droplet generator was used to calibrate and study some features of the forward-scattering spectrometer probe (FSSP). The generator produces a stable jet of monodisperse droplets with the rate of 50?500 droplets per second ...

Abstract: laciation in mixed-phase adiabatic cloudy parcels is investigated analytically using two new equations: the equation for coexistence of liquid water and ice and the mass balance equation. The analysis of glaciation time ...

Abstract: AbstractThe process of ice?liquid water interaction in the unsaturated environment is explored both analytically and with the help of a numerical simulation. Ice?liquid water interaction via the condensation?evaporation ...

Abstract: he process of collective diffusional growth of droplets in an adiabatic parcel ascending or descending with the constant vertical velocity is analyzed in the frame of the regular condensation approach. Closed equations for ...

Abstract: This paper considers the theory of diffraction image formation of spherical particles and peculiarities of particle sizing by discrete imaging probes. The diffraction images of spherical water droplets are approximated by ...

Abstract: irborne measurements of ice water content (IWC) in both ice and mixed-phase clouds remain one of the long-standing problems in experimental cloud physics. For nearly three decades, IWC has been measured with the help of ...

Abstract: The technique of using shadow images of particles, obtained in coherent illumination to measure particle size, is analyzed. The theory of Fresnel diffraction for an opaque disc was used to analyze shadow images of transparent ...

Abstract: The Rosemount Icing Detector (RICE) has been used extensively over the last three decades for aircraft measurements of the rate of ice riming in supercooled liquid and mixed clouds. Because of difficulties related to ...
