Evaluating CFSv2 Subseasonal Forecast Skill with an Emphasis on Tropical Convection
The deterministic predictive skill of CFSv2 is analyzed with respect to lead time and temporal averaging period. We also examine the spatial distributions of error and bias for synoptic-scale parameters and the impacts of ENSO on forecast skill. The errors in a small CFSv2 ensemble forecast …

Hurricane-generated ocean wave propagation and impacts on a fringing reef in Hawai’i
… include a detailed atmospheric model input (CFSv2), a simple parametric hurricane wind model, the parametric model blended with CFSv2 winds, and this blended product with a limited maximum wind speed. The results indicate that the blended and limited wind field produces wave model predictions …

Near Real-time Seasonal Drought Forecasting and Retrospective Drought Analysis using Simulated Multi- layer Soil Moisture from Hydrological Models at Sub- Watershed Scales
… (NCEP) coupled forecast system model version 2 (CFSv2) weather data is developed to forecast various water balance components including soil moisture (SM), actual evapotranspiration (ET), potential evapotranspiration ET (PET), and runoff (SURQ) for near-real time drought severity assessment, and …

Numerical modelling of Tropical Cyclone Dineo and its rainfall impacts over north-eastern South Africa
… Climate Forecast System Reanalyses version 2 (CFSv2) atmospheric reanalysis, satellite derived rainfall and wind data, and station rainfall data are used for this purpose. Tropical Rainfall Measuring Mission (TRMM) rainfall estimates, WRF model rainfall and rainfall station data indicated that …

Numerical modelling of the Angola Low and the Botswana High during a neutral and two El Ni˜no summers
… and 2015/16 using the WRF model. CFSR and CFSv2 reanalyses, satellite derived winds, GPCC rainfall and TRMM satellite-derived rainfall estimates are used to validate the model. The model was integrated from September through to April for each run with observed sea surface temperature and …

Integration of seasonal forecast information and crop models to enhance decision making in small-scale farming systems of South Africa
… officers. The Climate Forecast System version 2 (CFSv2) model-based forecasts were integrated with the Decision Support System for Agrotechnology Transfer (DSSAT) v4.7, a mechanistic crop model based on the Global Climate Model (GCM) approach. The GCM approach was the most appropriate technique …

Subseasonal to seasonal prediction and predictability of extreme and severe weather
… used as predictors. The model outperforms the CFSv2 at weeks 3-4 in the eastern US. Part II explores the mechanisms for atmospheric blocking onset and addresses how blocking impacts the prediction skill of the GEFSv12 over four sectors around the globe. Here, we objectively separate blocking …
