Assessment of GloSea4 seasonal forecasts for SADC and the global oceans

Author: Landman, WA ; Graham, R ; Knight, J ; Engelbrecht, C ; Olivier, C Date: Oct 2012 The main objective of this research is to demonstrate the skill of the UK Met Office Hadley Centre’s coupled global seasonal forecasting system, GloSea4, as a seasonal forecasting tool for the Southern African Development Community (SADC) and ...

Assessment of GloseA4 seasonal forecasts for SADC and the global oceans

Author: Landman, WA ; Graham, R ; Knight, J ; Engelbrecht, C ; Olivier, C Date: Sep 2012 Seasonal forecast skill over southern Africa may improve through the combination of forecasts. In the southern African region, however, only a small number of institutions have the capability to run global models operationally which can feed ... Read more
Downscaled climate change projections over northeastern South Africa: Implications for streamflow

Author: Mkhwanazi, M ; Landman, WA ; Engelbrecht, FA ; Olivier, C Date: Sep 2015 The study assesses the impacts of anthropogenic forcing on seasonal streamflows over northeastern South Africa by using both dynamically and statistically downscaled multi-decadal climate change projections. The statistical model approach is ... Read more
Dynamical seasonal climate prediction using an ocean-atmosphere coupled climate model developed in partnership between South Africa and the IRI

Author: Beraki, Asmerom F ; De Witt, DG ; Landman, WA ; Olivier, C Date: Feb 2014 The recent increase in availability of high-performance computing (HPC) resources in South Africa allowed the development of an ocean–atmosphere coupled general circulation model (OAGCM). The ECHAM4.5-South African Weather Service (SAWS) ... Read more
Ocean-atmosphere coupled climate model development at SAWS: description and diagnosis

Author: Beraki, Asmerom F ; DeWitt, D ; Landman, WA ; Olivier, C Date: Sep 2011 This paper introduces the South African Weather Service's coupled ocean-atmosphere model. The paper also demonstrates the advances made in configuring an operational coupled ocean-atmosphere model in South Africa for seasonal forecast production. ... Read more
River-flow predictions for the South African mid-summer using a coupled general circulation model

Author: Olivier, C ; Landman, WA ; Beraki, Asmerom F Date: Sep 2013 There are limited sources of streamflow data available in South Africa. These include simulated streamflow for catchments across South Africa and measured river-flow at specific rivers around the country. Given that a number of studies has ... Read more
Seasonal forecasts of the SINTEX-F coupled model applied to maize yield and streamflow estimates over north-eastern South Africa

Author: Malherbe, Johan ; Landman, WA ; Olivier, C ; Sakuma, H ; Luo, J-J Date: Jul 2014 Forecasts of a Global Coupled Model for austral summer with a 1 month lead are downscaled to end-of-season maize yields and accumulated streamflow over the Limpopo Province and adjacent districts in northeastern South Africa through application ...
