One-tiered vs. two-tiered forecasting of South African seasonal rainfall

Author: Landman, WA ; DeWitt, D ; Lotter, D Date: Sep 2010 The predictability of South African summer rainfall is investigated using coupled ocean-atmosphere models. Read more
Physiological responses of a fynbos legume, Aspalathus linearis to drought stress

Author: Lotter, D ; Valentine, AJ ; Van Garderen, EA ; Tadross, M Date: Jul 2014 Aspalathus linearis (rooibos) is a medicinally and economically useful shrub which is endemic to the Mediterranean west coast region of South Africa. Species distribution modelling indicates potentially severe consequences in range shift for ... Read more
Seasonal rainfall prediction skill over South Africa: one- versus two-tiered forecasting systems

Author: Landman, WA ; Dewitt, D ; Lee, D-E ; Beraki, Asmerom F ; Lotter, D Date: Apr 2012 Forecast performance by coupled ocean–atmosphere or one-tiered models predicting seasonal rainfall totals over South Africa is compared with forecasts produced by computationally less demanding two-tiered systems where prescribed sea surface ...

South African seasonal rainfall prediction performance by a coupled ocean-atmosphere model

Author: Landman, WA ; DeWitt, D ; Lee, D-E ; Beraki, Asmerom F ; Lotter, D Date: Dec 2010 Evidence is presented that coupled ocean-atmosphere models can already outscore computationally less expensive atmospheric models. However, if the atmospheric models are forced with highly skillful SST predictions, they may still be a very ... Read more
