The Numerical Forecast Model BKF(G): Characteristics And Experiences

The replacement of the GEOVOR computer at the German Military Geophysical Office (GMGO) near the end of 1986 made possible the use of better atmospheric models due to increased computing capacity. Specifically, the synoptic scale models 7LPE-CM (hemispheric, gridpoint spacing 381 km) and 7LPE- LFM (...

Description
Summary:The replacement of the GEOVOR computer at the German Military Geophysical Office (GMGO) near the end of 1986 made possible the use of better atmospheric models due to increased computing capacity. Specifically, the synoptic scale models 7LPE-CM (hemispheric, gridpoint spacing 381 km) and 7LPE- LFM (North Atlantic/European window, gridpoint spacing 127 km) were replaced by a more powerful model. These models, used by the GMGO since 1982, were limited by the model physics and numerical methods available in 1980. Advancements in these fields gave modelers the power to upgrade these models. Due to the existing cooperation between the DWD and the GMGO in the area of model development, an agreement was reached to implement the DWD hemispheric model BKF at the GMGO in a version specifically adapted to the GEOVOR computer system. This new version is called the BKFG (G for GMGO). After extensive program adaptation and testing, the BKFG was available for routine use on GEOVOR and replaced the 7LPE as the standard GMGO model on 3 May 1988.
