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 how these fundamental results may enhance real-time space weather forecasts.

We focus on a combination of numerical and empirical techniques, leading to hyperfast models, which are further optimized with parallel computation. The advantage of this approach is that in physical modeling, we can apply ensemble simulations to cover the full parameter space. In real-time modeling, the same simulations are fast enough to be actually applicable in real-time.

In this way we are also able to couple our models from the coronal magnetic field to the solar wind including CMEs with effects at Earth, such as the aurora and geomagnetically induced currents.
