Model evaluation for seasonal forecasting over southern Africa
… broader effort of institutions toward improving seasonal forecasts over southern Africa. The primary objective is to understand where global models show shortcomings in their simulations, and how this impacts on their seasonal forecast skill. It is proposed that the skill of a model in simulating …

Assessing seasonal forecast use in Western Cape viticulture: a risk framework approach
… type of farming is under significant threat. Seasonal forecasts (SF) offer the potential to reduce farmer's vulnerability to climate risks by offering advanced climate information. This study aims to use a risk management framework to identify and compare the level of risk involved in using or …

Towards effective use of climate forecasts in agricultural decision making: Bridging the gap between modeling and empirical studies
Weather and climate forecasts offer great potential for managing climate variability and climate risk in agricultural systems. In particular, climate forecasts at the seasonal scale can be considered as a key component of proactive drought management. However, there is not much evidence of …

An examination of the large-scale drivers of North Atlantic vertical wind shear and seasonal tropical cyclone variability
… wind shear (VWS). VWS is a key variable for the seasonal prediction of tropical cyclone (TC) activity and can be used to assess sources of predictability within a given season. Part 1 of the dissertation examines tropical versus subtropical impacts on TC activity by considering large-scale …

Integration of seasonal forecast information and crop models to enhance decision making in small-scale farming systems of South Africa
… decisions under such conditions. Integrated seasonal forecast information and crop models have been used as a tool that enhances decision making in some countries. Utilization of such an approach in South Africa can enhance decision making in climate variability management. The study …

Event characteristics of intra-seasonal climate circulations
… variability and the general circulation. Seasonal rainfall totals are clearly linked to significant rain days, indicating the importance of evaluating synoptic-scale event characteristics. Rank ordered rainfall characteristics reveal that normal rainfall may be considered as the middle …

General Circulation Model Regional Predictions Using MOS techniques: Seasonal Forecasting
… used to provide more accurate and coherent seasonal forecasts. However, they still show some limitations. Model Output Statistics (MOS) approaches may improve performance if observed and forecast values are available for a long record. This study investigates the skills of a MOS approach on …

Southern African climate anomalies, summer rainfall and the Angola low
… which contribute to acute food shortage. Seasonal rainfall forecasts are an important management tool for donor countries as well as local farmers. The failure to utilize forecasts based on sound scientific knowledge would negate attempts at achieving food security (W orId Meteorological …

The role of indigenous and local knowledge on climate adaptation for smallholder farmers in Chiredzi, Zimbabwe
… multiple regions of the world rely on IK and LK forecasts for climate decision making. This knowledge provides a rich foundation for locally led adaptation by smallholder farmers because of its contextual embeddedness within microclimatic conditions. Recent peer-reviewed literature on IK and LK …
