RISThe Mesoscale and Microscale Structure and Organization of Clouds and Precipitation in Midlatitude Cyclones. Part XV: A Numerical Modeling Study of Frontogenesis and Cold-Frontal Rainbands
Publisher: American Meteorological Society
Abstract: A two-dimensional, hydrostatic, primitive-equation model is used to investigate the dynamics of frontogenesis in a moist atmosphere. The development of a cold front is simulated through shear-deformation associated with ...
Frontal Interaction with Mesoscale Topography
Publisher: American Meteorological Society
Abstract: A two-dimensional, hydrostatic, nearly adiabatic primitive equation model is used to study the evolution of a front passing across topography. Frontogenesis is forced by shearing deformation associated with the nonlinear ...
Frontal Interaction with the Appalachian Mountains. Part I: A Climatology
Publisher: American Meteorological Society
Abstract: A comparison between the climatological structure of retarded and unretarded fronts aligned parallel to the Appalachian Mountains is investigated. With the average height of the Appalachians being 1 km, retarded and ...
A General Circulation Experiment with a Coupled Atmosphere, Ocean and Sea Ice Model
Publisher: American Meteorological Society
Abstract: This paper describes the construction and results of a comprehensive, three-dimensional general circulation model (GCM) of the earth's climate. The model, developed at the National Center for Atmospheric Research (NCAR), ...
South American Cold Surges: Types, Composites, and Case Studies
Publisher: American Meteorological Society
Abstract: This paper examines the climatological, large-scale, and synoptic-scale aspects of South American cold surges using NCEP?NCAR gridded reanalyses for the 1992?96 period. Three common cold surge types are identified on the ...
