Several workstation system architecture changes were made during the port to Workstation/Unix environment. These included a workstation redesigned using object-oriented programming, an integrated user interface, localization software and local data ingest, and graphics rendering on-the-fly. Rendering on-the-fly greatly simplified data management, background tasks, and display resolution issues, but has not fully met all of the initial performance requirements set down by the AWIPS program at its inception 15 years ago.
Important additional elements have recently been added to the workstation which address new requirements such as gridded forecast preparation and severe weather decision support. Gridded forecast preparation, in particular, is redefining how forecasters prepare and generate forecast information. Data volumes have also increased dramatically since the system was initially deployed, and this trend will continue in the future. How forecasters will make optimal use of the data and workstation features during warning operations and in support the National Digital Forecast Database are also key factors to evaluate. This paper will examine these factors and summarize design features which need to be addressed for the next-generation FX meteorological workstation.
