RISBaroclinic Waves and Frontogenesis in a Non-Uniform Potential Vorticity Semi-Geostrophic Model
Publisher: American Meteorological Society
Abstract: A three-dimensional semi-geostrophic model is used to study the nonlinear development of baroclinic waves on a zonal jet in a model atmosphere with a large change in potential vorticity in the region of the tropopause. The ...
An Example of Hurricane Tracking and Forecasting with a Global Analysis-Forecasting System
Publisher: American Meteorological Society
Abstract: The tracking of Hurricane Elena by the ECMWF operational analysis system is compared with reported positions from reconnaissance aircraft and coastal radar. An example forecast is shown for the operational model and also ...
An Evaluation of the Performance of the ECMWF Operational System in Analyzing and Forecasting Easterly Wave Disturbances over Africa and the Tropical Atlantic
Publisher: American Meteorological Society
Abstract: Substantial changes were made to the ECMWF model in May 1985. The extensive revisions to the physical parameterizations were designed to improve the treatment of the large-scale flow in the tropics. In addition, the ...
