A General Method for Estimating Bulk 2D Projections of Ice Particle Shape: Theory and Applications
Publisher: American Meteorological Society
Abstract: The orientation of falling ice particles directly influences estimates of microphysical and radiative bulk quantities as well as in situ retrievals of size, shape, and mass. However, retrieval efforts and bulk calculations ...
X-Band Polarimetric and Ka-Band Doppler Spectral Radar Observations of a Graupel-Producing Arctic Mixed-Phase Cloud
Publisher: American Meteorological Society
Abstract: haracteristics of graupel in an Arctic deep mixed-phase cloud on 7 December 2013 were identified with observations from an X-band scanning polarimetric radar and a Ka-band zenith-pointing radar in conjunction with scattering ...
Shapes and Fall Orientations of Ice Particle Aggregates
Publisher: American Meteorological Society
Abstract: AbstractTesting the often-made assumption that ice particle aggregates (snowflakes) are well represented by oblate spheroids, ellipsoid fits are applied to aggregate images. An algorithm to retrieve both the ellipsoidal ...
What Can We Conclude about the Real Aspect Ratios of Ice Particle Aggregates from Two-Dimensional Images?
Publisher: American Meteorological Society
Abstract: simple numerical experiment was performed to investigate the result published in many papers that measurements indicate that aggregates may be well represented as oblate spheroids with mean aspect ratio (semiminor axis to ...
Comparisons of Electromagnetic Scattering Properties of Real Hailstones and Spheroids
Publisher: American Meteorological Society
Abstract: Severe (>2.5 cm) hail causes >$5 billion in damage annually in the United States. However, radar sizing of hail remains challenging. Typically, spheroids are used to represent hailstones in radar forward operators and to ...
