Author:Landman, WA; Engelbrecht, FA; McGregor, JL; van der Merwe, JHDate:Oct 2014Three aspects of seasonal forecast modelling when using an atmospheric general circulation model (AGCM) are presented in this paper. The first aspect deals with the verification of simulations created by forcing the AGCM at its lower boundary ...Read more
Author:Landman, WA; Beraki, Asmerom F; DeWitt, DDate:Dec 2009Retro-active forecasts produced at a 1-month lead-time by the ECHAM4.5 AGCM are statistically downscaled to South African district rainfall totals for the austral mid-summer season of December to February. The AGCM is forced with SST forecasts ...Read more
Author:Muchuru, S; Landman, WA; DeWitt, DGDate:Oct 2015Seasonal climate forecasts are operationally produced at various climate prediction centres around the world. However, these forecasts may not necessarily be appropriately integrated into application models in order to help with decision-making ...Read more
Author:Lazenby, MJ; Landman, WA; Garland, Rebecca M; DeWitt, DGDate:Oct 2014An assessment of probabilistic prediction skill of seasonal temperature extremes over Southern Africa is presented. Verification results are presented for six run-on seasons; September to November, October to December, November to January, ...Read more
