Evolution of coronal mass ejections in the inner heliosphere: observations and modeling
Abstract
The vast variety of past and current remote-sensing and in situ observations has enabled deepening our knowledge in numerous aspects of our Sun's activity and production. Moreover, the increasing demand of specialized space weather forecasts that address the needs of commercial and government systems has also proliferated. This is an overview of the most prominent and recent theoretical and empirical models/techniques of increasing complexity that have been developed to date, to understand the propagation and evolution of coronal mass ejections in the inner heliosphere. On the practical side, several of these models and methods are aimed at forecasting position, embedded flux rope magnetic field configuration, and time of arrival at 1 AU of these disturbances, with the ultimate goal of assessing their degree of geoeffectiveness. The methods to be addressed involve a wealth of data sets from ground- and space-based instrumentation, ranging from remote-sensing observations of the solar atmosphere and inner heliosphere, to detections of radio waves and in situ measurements.
