Operational Application of the UW Cloud-Top Cooling Algorithm: Large Hail Forecasting
Forecasting the initiation, intensity, and duration of severe convective events remains a significant challenge for operational weather forecasters. Even with continual increases in operational forecast model spatial resolution, numerical models remain unable to simulate mesoscale phenomena with …

Improvement of aftershock models based on Coulomb stress changes and rate-and-state dependent friction
… being made to extend the scope of such models to operational earthquake forecasting. The overarching goal of the research presented in this thesis is to improve physics-based earthquake forecasts, with a focus on aftershock sequences. Physical models of triggered seismicity are based on the …

Characteristics of deep moist convection and rainfall in cut-off lows over South Africa
… of COL events from this study can improve the operational forecasting of these weather systems over the country.

Dynamical processes in the evolution of Cut Off Lows over South Africa
… and the BRT affects COLs negatively. The operational forecasting of these weather systems across the nation can be enhanced by the application of the knowledge about the evolution in the characteristics of COL events from this study.

Impacts of cold pool strength on tornado production in quasi-linear convective systems
… s−2 and 0–3 km SRH of at least 200 m2 s−2. For operational forecasting, it follows that cold pool characteristics are not nearly as important as assessing vertical wind shear when aiming to predict the tornadic potential of a QLCS, particularly in the cold and spring seasons.

Quantifying the SST biases in data assimilative ocean simulations of the Benguela Upwelling System
… studies, there is no regionally tailored ocean forecasting system that is explicitly developed to deal with the unique ocean dynamics of the Benguela. In this study, the Hybrid Coordinate Ocean Model (HYCOM) is used in conjunction with the Ensemble Optimal Interpolation (EnOI) assimilation …

A Methodology for Improved, Data-Oriented, Air Quality Forecasting
… things negative effects on health. Air quality forecasting system can potentially facilitate amelioration of the situation by providing alerts regarding potential high air pollution levels to the public (to enable them to minimise their personal air pollution exposure) and to the authorities …

Modelling of low- and high-frequency sea level variability and their drivers around the southern African coast
Recent surveys indicate that marine operational forecasting is becoming increasingly important due the pressure to manage impacts associated with our changing climate. The methods with which forecasts are being produced are also changing as computational power is becoming more accessible. …
