RISAnalysis and Diagnosis of the Composition of Ageostrophic Circulations in Jet-Front Systems
Publisher: American Meteorological Society
Abstract: Diagnostic case studies of ageostrophic circulations in upper-tropospheric jet-front systems are presented, using the numerical analyses of the ECMWF model as data sources. The impact of the ECMWF analysis procedure on the ...
Location and Interaction of Upper- and Lower-Troposphere Adiabatic Frontogenesis
Publisher: American Meteorological Society
Abstract: Both upper-air and surface frontogenesis have often been depicted as processes whose dynamics could he reduced to 2D balanced problems in which ?self-sharpening? configurations could be highlighted. This paper reports on ...
A Case Study of Coupling between Low- and Upper-Level Jet–Front Systems: Investigation of Dynamical and Diabatic Processes
Publisher: American Meteorological Society
Abstract: An example of coupling between an upper-level and a low-level jet?front system is analyzed using the mesoscale hydrostatic model SALSA. The case study chosen is the cold front sampled during the intensive observation period ...
Case Study and Climatological Analysis of Upper-Tropospheric Jet Stream and Stratosphere–Troposphere Exchanges Using VHF Profilers and Radionuclide Measurements in France
Publisher: American Meteorological Society
Abstract: AbstractThe authors present a climatological analysis of tropospheric horizontal wind profiles and jet stream events using long series of wind profiles from two VHF profilers located in France: Lannemezan (2001?14) and ...
The Fronts and Atlantic Storm-Track Experiment (FASTEX): Scientific Objectives and Experimental Design
Publisher: American Meteorological Society
Abstract: The Fronts and Atlantic Storm-Track Experiment (FASTEX) will address the life cycle of cyclones evolving over the North Atlantic Ocean in January and February 1997. The objectives of FASTEX are to improve the forecasts of ...
