RISComparisons of the Electrostatic Disdrometer with Impactor Slides
Publisher: American Meteorological Society
Abstract: Detailed comparisons of measurements from the electrostatic disdrometer and from soot-coated impactor slides show consistent differences in droplet size distributions determined by the two techniques. The disdrometer-derived ...
Evaluation of the Forward Scattering Spectrometer Probe. Part I: Electronic and Optical Studies
Publisher: American Meteorological Society
Abstract: Laboratory studies of the Forward Scattering Spectrometer Probe (FSSP), were conducted to better understand the operation, to determine limitations and to define the measurement accuracy of the instrument for airborne cloud ...
Evaluation of the Forward Scattering Spectrometer Probe. Part II: Corrections for Coincidence and Dead-Time Losses
Publisher: American Meteorological Society
Abstract: Cloud particle concentrations measured by the Forward Scattering Spectrometer Probe (FSSP) can be underestimated when particles are either coincident or pass through the sensing area of the probe during the electronic ...
Observed Enhancement of Reflectivity and the Electric Field in Long-Lived Florida Anvils
Publisher: American Meteorological Society
Abstract: A study of two long-lived Florida anvils showed that reflectivity >20 dBZ increased in area, thickness, and sometimes magnitude at the midlevel well downstream of the convective cores. In these same regions electric fields ...
The Relationship Between Radar Reflectivity Factor and Hail at the Ground for Northeast Colorado Thunderstorms
Publisher: American Meteorological Society
Abstract: Data from the hailpad network of the National Hail Research Experiment were examined in relation to the equivalent radar reflectivity factors recorded in the lowest level sweeps of the radar beam over the pads during ...
The Microstructure of Clouds in the High-Frequency Hail Area of Kenya
Publisher: American Meteorological Society
Abstract: During June 1977 ground-based measurements of the CCN spectrum were made twice daily near Kericho, Kenya, and two flights were flown in that region to investigate the microstructure of the clouds. Both the CCN and the ...
An Electrostatic Cloud Droplet Probe
Publisher: American Meteorological Society
Abstract: An electrostatic cloud droplet sizing device (electrostatic disdrometer) originally developed by Keily and Millen has been tested, modified extensively, and calibrated in our laboratory. The investigations have shown that ...
Dynamical-Microphysical Evolution of a Convective Storm in a Weakly-Sheared Environment. Part II: Airflow and Precipitation Trajectories from Doppler Radar Observations
Publisher: American Meteorological Society
Abstract: Measurements from three Doppler radars of air motion and observations of the environment and storm reflectivity structure, supplemented by aircraft measurements of precipitation and cloud particles, are used to establish ...
Dynamical-Microphysical Evolution of a Convective Storm in a Weakly-Sheared Environment. Part I: Microphysical Observations and Interpretation
Publisher: American Meteorological Society
Abstract: Aircraft measurements of microphysical thermodynamic, and vertical air motion properties supplemented by radar measurements of reflectivity structure are used to investigate precipitation development throughout much of the ...
