In order to improve the predictions of the solar wind environment at planets, moons, comets and interplanetary spacecraft, we study the temporal evolution and spatial variation of solar wind structures. Special emphasis is put on the fast and slow solar wind stream interaction regions (SIRs or CIRs). Currently, a huge fleet of solar observatories is available throughout the inner heliosphere, hence a multi-spacecraft study of the propagation and evolution of these structures is possible. We improve solar wind predictions by removing ICME signatures from the input data to reduce the number of false alarms. Ballistic radial propagation models are refined by pressure correction at CIRs. Latitudinal effects are taken into account to improve the models and to extend our predictions to three dimensions.
