Example of our THUX solar wind model with overlaid solar storm fronts (shown in blue and red).
With Helio4Cast we strive to bridge the gap between basic research and real-time space weather forecasts. We work on a better physical understanding and modeling of the evolution of solar storms and high-speed solar wind streams, and check how these fundamental results may enhance real-time space weather forecasts.
We focus on a combination of numerical and empirical modeling, which allows to apply the similar simulations that we use for research also in a real-time setting.
