Simulation of the 23 July 2012 extreme space weather event: What if this extremely rare CME was Earth directed?

Modeling a space weather event from the Sun to the Earth: CME generation and interplanetary propagation

[1] We present a three-dimensional (3-D) numerical ideal magnetohydrodynamics (MHD) model describing the time-dependent expulsion of a coronal mass ejection (CME) from the solar corona propagating to 1 astronomical unit (AU). The simulations are performed using the Block Adaptive Tree Solar-Wind Roe Upwind Scheme (BATS-R-US) code. We begin by developing a global steady-state model of the corona...

Integrated Frameworks for Earth and Space Weather Simulation

Simulations of Earth and space weather require the representation and coupling of distinct physical domains in a flexible, computationally efficient manner. There is increasing call to interface Earth and space models, as the interplay of phenomena between these domains is an active topic of basic research, and a key factor in operational prediction systems. Software frameworks have been develo...

Rare-Event Simulation

Rare events are events that are expected to occur infrequently or, more technically, those that have low probabilities (say, order of 10 3 or less) of occurring according to a probability model. In the context of uncertainty quantification, the rare events often correspond to failure of systems designed for high reliability, meaning that the system performance fails to meet some design or opera...
