RISNonlinear Wind Analysis of Single-Doppler Radar Observations within a DVAD Framework
Publisher: American Meteorological Society
Abstract: he application of the distance velocity azimuth display (DVAD) method to the retrieval of vertical wind profiles from single-Doppler radar observations is presented in this study. It was shown that Doppler velocity ...
The Genesis of Mesovortices within a Real-Data Simulation of a Bow Echo System
Publisher: American Meteorological Society
Abstract: he genesis of two mesovortices (MVs) within a real-data, convection-resolving simulation of the 8 May 2009 central U.S. bow echo system is studied. Both MVs form near the bow apex but differ distinctively in intensity, ...
Momentum Flux and Flux Divergence of Gravity Waves in Directional Shear Flows over Three-Dimensional Mountains
Publisher: American Meteorological Society
Abstract: inear mountain wave theory is used to derive the general formulas of the gravity wave momentum flux (WMF) and its vertical divergence that develop in directionally sheared flows with constant vertical shear. Height variations ...
Mesovortices within the 8 May 2009 Bow Echo over the Central United States: Analyses of the Characteristics and Evolution Based on Doppler Radar Observations and a High-Resolution Model Simulation
Publisher: American Meteorological Society
Abstract: derecho-producing bow-echo event over the central United States on 8 May 2009 is analyzed based on radar observations and a successful real-data WRF simulation at 0.8-km grid spacing. Emphasis is placed on documenting the ...
Reassessing the Use of Inner-Core Hot Towers to Predict Tropical Cyclone Rapid Intensification
Publisher: American Meteorological Society
Abstract: he hot tower (HT) in the inner core plays an important role in tropical cyclone (TC) rapid intensification (RI). With the help of Tropical Rainfall Measurement Mission (TRMM) data and the Statistical Hurricane Intensity ...
Study of Electromigration Induced Stress of Solder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study designed and produced a special microsolder specimen (Sn3.8Ag0.7Cu) to equalize current density under stressing. The specimen was generated to avoid temperature gradient and thermal migration. The inelastic ...
Quantifying the effect of horizontal propagation of three-dimensional mountain waves on the wave momentum flux using Gaussian beam approximation
Publisher: American Meteorological Society
Abstract: his work examines the influence of horizontal propagation of three-dimensional (3D) mountain waves on the wave momentum flux (WMF) within finite domains (e.g., the grid cell of general circulation models). Under the ...
Review of Aerosol–Cloud Interactions: Mechanisms, Significance, and Challenges
Publisher: American Meteorological Society
Abstract: ver the past decade, the number of studies that investigate aerosol?cloud interactions has increased considerably. Although tremendous progress has been made to improve the understanding of basic physical mechanisms of ...
Evaluation of Chinese Aircraft Meteorological Data Relay (AMDAR) Weather Reports
Publisher: American Meteorological Society
Abstract: ircraft Meteorological Data Relay (AMDAR) weather reports are a type of high spatiotemporal data currently widely used in weather monitoring and prediction. A recent Chinese AMDAR project began in 2003 has made rapid ...
Evaluation of Accuracy of Chinese AMDAR Data for 2015
Publisher: American Meteorological Society
Abstract: AbstractTwo comparative studies have been performed to evaluate the accuracy of Chinese Aircraft Meteorological Data Relay (AMDAR) weather reports. The comparison between AMDAR reports and radiosonde observations shows ...
