Solar wind transients, i.e. coronal mass ejections (CMEs), their associated interplanetary shocks and corotating interaction regions (CIRs) drive space weather throughout the heliosphere, causing various interplanetary as well as planetary disturbances. Therefore, the prediction of their arrival and impact is extremely important for the modern space-exploration and electronics-dependent society. Significant efforts have been made in the past decade to develop and improve the prediction capabilities, through both state-of-the art observations and modelling. Although significant progress has been made, many new challenges have been revealed. We are limited in obtaining reliable observation-based input for the models, tracking CMEs and CIRs throughout the heliosphere and reliably evaluating prediction models. These challenges can be tackled by exploiting and improving our existing capabilities, as well as using the out-of-the-box thinking and break from the traditional methods and data. This session is devoted to provide an overview of the current state of the space weather prediction of the arrival time and impact of solar wind transients and to introduce new and promising observational and modelling capabilities.
We solicit abstracts on observational and modelling efforts, as well as space weather prediction evaluation. Emphasis will be placed on the multi-spacecraft and multi-instrument observational approaches, data-driven modelling, and community established evaluation measures. With the overview of our current capabilities and possible future prospects we aim to highlight guidelines to the general direction of the future scientific efforts, as well as space-mission planning.
