Some Observations of Vertical Velocity Skewness in the Convective Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: Previously published profiles of vertical velocity (w) skewness observed in the convective atmospheric boundary layer show deficits in the upper part of the layer, relative to large eddy simulations designed to apply to ...
Momentum Transport by a Line of Cumulonimbus
Publisher: American Meteorological Society
Abstract: The vertical transport of horizontal momentum normal to a line of cumulonimbus observed during GATE on 14 September 1974 is against the vertical momentum gradient, contrary to the predictions of mixing-length theory. Data ...
The Structure and Dynamics of Horizontal Roll Vortices in the Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: The wind and temperature fields of the Planetary boundary layer (PBL) are investigated during periods in which horizontal roll vortices are present. Measurements from a 444 m tower and from inertially-stabilized aircraft ...
Women in Meteorology
Publisher: American Meteorological Society
Abstract: A survey of women atmospheric scientists has been completed in late 1973 and is briefly summarized in this article. Complete results are on file at the Head-quarters of The American Meteorological Society. For the United ...
Vertical Velocity Characteristics of Oceanic Convection
Publisher: American Meteorological Society
Abstract: Oceanic cumulonimbus updraft and downdraft events observed in the Western Pacific during the TAMEX program by NOAA P-3 research aircraft are analyzed and discussed. The basic dataset consists of flight-level data from 10 ...
Vertical Velocity and Buoyancy Characteristics of Coherent Echo Plumes in the Convective Boundary Layer, Detected by a Profiling Airborne Radar
Publisher: American Meteorological Society
Abstract: Aircraft and airborne millimeter-wave radar observations are used to interpret the dynamics of radar echoes and radar-inferred updrafts within the well-developed, weakly sheared continental convective boundary layer. ...
The Use of Inertial Altitude in the Determination of the Convective-Scale Pressure Field over Land
Publisher: American Meteorological Society
Abstract: Pressure perturbations are measured from an aircraft by subtracting its pressure altitude from its actual altitude. The pressure perturbation is equal to the resulting ?D-value? multiplied by the acceleration of gravity ...
Momentum and Mass Transport by Convective Bands: Comparisons of Highly Idealized Dynamical Models to Observations
Publisher: American Meteorological Society
Abstract: The effects of quasi-two-dimensional convective bands on the environmental flow are investigated by comparing the observed mass and momentum fluxes and horizontal pressure changes to those predicted by the Moncrieff ...
How Representative are AMS Membership Surveys?
Publisher: American Meteorological Society
Abstract: s regarding the fractional participation of women in meteorology/atmospheric sciences gathered by the AMS are quite similar to those based on annual National Science Foundation (NSF) surveys. The absolute numbers in the ...
Cumulonimbus Vertical Velocity Events in GATE. Part I: Diameter, Intensity and Mass Flux
Publisher: American Meteorological Society
Abstract: This is the first part of a two-part paper defining the nature of the vertical air motion in and around GATE cumulonimbus clouds. The statistics are from a total of 104 km of flight legs, flown on six days in GATE, at ...
