RISAssociations between the Global Energy Cycle and Regional Rainfall in South Africa and Southwest Australia
Publisher: American Meteorological Society
Abstract: Large-scale atmospheric processes in the Southern Hemisphere are examined on both seasonal and daily time scales in order to seek associations between these and regional rainfall variability in the summer rainfall areas ...
Application of the NCEP Ensemble Prediction System to Medium-Range Forecasting in South Africa: New Products, Benefits, and Challenges
Publisher: American Meteorological Society
Abstract: The National Centers for Environmental Prediction (NCEP) Ensemble Forecasting System (EFS) is used operationally in South Africa for medium-range forecasts up to 14 days ahead. The use of model-generated probability forecasts ...
Using a Stochastic Kinetic Energy Backscatter Scheme to Improve MOGREPS Probabilistic Forecast Skill
Publisher: American Meteorological Society
Abstract: n improved stochastic kinetic energy backscatter scheme, version 2 (SKEB2) has been developed for the Met Office Global and Regional Ensemble Prediction System (MOGREPS). Wind increments at each model time step are derived ...
A New HadGEM3-A-Based System for Attribution of Weather- and Climate-Related Extreme Events
Publisher: American Meteorological Society
Abstract: new system for attribution of weather and climate extreme events has been developed based on the atmospheric component of the latest Hadley Centre model. The model is run with either observational data of sea surface ...
