Résumé(disponible en anglais seulement)
The connection between solar activity and adverse phenomena in the Earth's environment that can affect space and ground based technologies has spurred interest in the Space Weather (SW) research. Since the most reliable observations, from the L1 point, allow only ~1h advanced warning of approaching solar disturbances, a great effort has been put on the development of suitable models that can provide longer predictions of the SW events. With the progress in computational technology it is possible now to develop operational large scale physics based models which can incorporate most important physical processes and domains of the Sun-Earth system. In order to enhance our SW prediction capabilities we are placing efforts to develop advanced numerical tools. With operational requirements in mind, our goal is to develop a modular simulation framework of propagation of the solar disturbances through interplanetary space. Here, we report and discuss our efforts on the development of coronal field and solar wind components for a large scale MHD code. The model for the components is based on a potential field source surface model and an empirical Wang-Sheeley-Arge solar wind relation.
