RISDiagnostic and Forecast Graphics Products at NMC Using High Frequency Model Output
Publisher: American Meteorological Society
Abstract: Archived hourly output from the National Meteorological Center (NMC) prediction models has provided the basis for advanced graphic diagnostic and forecast tools. The high-frequency data are available on a regional selected ...
Discrimination of Mixed- versus Ice-Phase Clouds Using Dual-Polarization Radar with Application to Detection of Aircraft Icing Regions
Publisher: American Meteorological Society
Abstract: Dual-polarization radar measurements and in situ measurements of supercooled liquid water and ice particles within orographic cloud systems are used to develop probabilistic criteria for identifying mixed-phase versus ...
Structure and Statistical Analysis of the Microphysical Properties of Generating Cells in the Comma Head Region of Continental Winter Cyclones
Publisher: American Meteorological Society
Abstract: his paper presents analyses of the microphysical structure of cloud-top convective generating cells at temperatures between ?10° and ?55°C across the comma head of 11 continental cyclones, using data collected by the W-band ...
Microphysical Properties of Convectively Generated Fall Streaks within the Stratiform Comma Head Region of Continental Winter Cyclones
Publisher: American Meteorological Society
Abstract: his paper presents analyses of the microphysical structure of comma head stratiform precipitation in 14 continental cyclones, focusing on fall streaks of hydrometeors produced by cloud-top convective generating cells. Data ...
The Climate Impact of Past Changes in Halocarbons and CO2 in the Tropical UTLS Region
Publisher: American Meteorological Society
Abstract: chemistry?climate model coupled to an ocean model is used to compare the climate impact of past (1960?2010) changes in concentrations of halocarbons with those of CO2 in the tropical upper troposphere and lower stratosphere ...
Eta Model Precipitation Forecasts for a Period Including Tropical Storm Allison
Publisher: American Meteorological Society
Abstract: A step-mountain (eta) coordinate limited-area model is being developed at the National Meteorological Center (NMC) to improve forecasts of severe weather and other mesoscale phenomena. Precipitation forecasts are reviewed ...
Separating the Dynamical Effects of Climate Change and Ozone Depletion. Part I: Southern Hemisphere Stratosphere
Publisher: American Meteorological Society
Abstract: A version of the Canadian Middle Atmosphere Model that is coupled to an ocean is used to investigate the separate effects of climate change and ozone depletion on the dynamics of the Southern Hemisphere (SH) stratosphere. ...
Vertical Velocity and Physical Structure of Generating Cells and Convection in the Comma Head Region of Continental Winter Cyclones
Publisher: American Meteorological Society
Abstract: he vertical motion and physical structure of elevated convection and generating cells within the comma heads of three continental winter cyclones are investigated using the Wyoming W-band cloud radar mounted on the National ...
Separating the Dynamical Effects of Climate Change and Ozone Depletion. Part II: Southern Hemisphere Troposphere
Publisher: American Meteorological Society
Abstract: The separate effects of ozone depleting substances (ODSs) and greenhouse gases (GHGs) on forcing circulation changes in the Southern Hemisphere extratropical troposphere are investigated using a version of the Canadian ...
