Practical considerations and limitations
- The model is initialized using publicly available GFS data. The GFS forecasts are also viewable here
- The model requires spin-up time to become numerically stable, the first hour of the forecast should be discarded
- For observed Skew-T diagrams please visit the University of Wyoming Upper-Air Database
- Customized forecast products is available on request
- Please note that SAWS is the only entity in South-Africa which can issue weather related warnings
