Verification of high speed solar wind stream forecasts
High-speed solar wind streams emanating from coronal holes are frequently impinging on the Earth's magnetosphere causing recurrent, medium-level geomagnetic activity. Modeling high-speed solar wind streams is thus an essential element of successful space weather forecasting.
The presentation will focus on quantification and validation of operational high-speed solar wind stream forecasts made by the Empirical Solar Wind Forecast (ESWF) and the semiempirical Wang-Sheeley-Arge (WSA) model. We will discuss validation and verification techniques and present the advantages and disadvantages of the investigated forecast models.
