Solar-terrestrial Simulations in the STEREO Era
Abstract
Due to the scarcity of heliospheric observations, over the past decade global 3-D numerical simulations have become increasingly important in studying the propagation of coronal mass ejections (CMEs) from the Sun to the Earth. Since the launch of STEREO in November 2006, continuous white-light observations of solar transients on their way to the Earth in near-real time have become possible.
In this talk, we will discuss the significance of 3-D simulations in the interpretation of observations taken by the Heliospheric Imagers. We will focus on a series of two ejections in January, 24-25, 2007, which have been simulated with the Space Weather Modeling Framework (SWMF). We will present detailed comparisons between real and simulated time-elongation plots and discuss the appearance of CME-CME interaction in real and synthetic observations.- Publication:
