On Aerosol Direct Shortwave Forcing and the Henyey–Greenstein Phase Function
Publisher: American Meteorological Society
Abstract: This technical note extends previous Mie calculations to show that there are complex relationships between the asymmetry parameter g and the upscatter fractions for monodirectional incident radiation ?(?0). Except for ...
GCM Estimate of the Indirect Aerosol Forcing Using Satellite-Retrieved Cloud Droplet Effective Radii
Publisher: American Meteorological Society
Abstract: In a recent paper, Han et al. analyzed satellite data radiances to retrieve cloud droplet effective radii and reported significant interhemispheric differences for both maritime and continental clouds. The mean cloud droplet ...
Mesoscale History of a Small Patch of Clear Air Turbulence
Publisher: American Meteorological Society
Abstract: Sequential analyses of data from a network of eight special rawinsonde stations 100 km apart demonstrate the important effects of mesoscale disturbances in a 2½-hr episode of light-to-moderate clear air turbulence (CAT). ...
Relationships Between the Size of Satellite-Observed Cirrus Shields and the Severity of Thunderstorm Complexes
Publisher: American Meteorological Society
Abstract: Seventeen thunderstorm complexes, observed by TIROS satellite over the United States, were investigated. The diameter of the conspicuously bright storm cloud shield, composed of integrated thunderstorm anvils, has been ...
SYNOPTIC-PHYSICAL IMPLICATIONS OF 1.25-CM VERTICAL-BEAM RADAR ECHOES
Publisher: American Meteorological Society
Abstract: More than 1000 hr of radar records taken with the APS-34 1.25-cm vertical-beam radar during a four-year period have been readily classified into four clearly recognizable types. A limited number of precipitation growth ...
Performance Augmentation of Underactuated Fingers' Grasps Using Multiple Drive Actuation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the performance augmentation of underactuated fingers through additional actuators is presented and discussed. Underactuated, also known as self-adaptive, fingers typically only rely on a single actuator for ...
Doppler Radar Observation of Wind Structure in Snow
Publisher: American Meteorological Society
Abstract: Sinusoidal variations in the longitudinal speed of the wind in the planetary boundary layer are observed with a C-band multiple-gate Doppler radar using snow as a wind tracer. These undulations in the horizontal wind are ...
A Simple Model of the Transient Response of the Thermosphere to Impulsive Forcing
Publisher: American Meteorological Society
Abstract: Substantial variations in density, temperature and winds in the high-latitude thermosphere during geomagnetic substorms have been recorded using a wide variety of observational techniques. The disturbed state of the ...
THE MOTION AND PREDICTABILITY OF PRECIPITATION LINES
Publisher: American Meteorological Society
Abstract: Analysis of radar film from New England and the midwest has shed additional light on the relation of precipitation-line motion to upper winds, the direction of motion, the line lifetimes and the regious of appearance and ...
