WebJul 1, 2013 · Geoeffectiveness of ICMEs with different structures/features. The CMEs ejected from the Sun and propagating into interplanetary space may be fast enough to compress the ambient plasma and field and from a shock/sheath region ahead of them. However, many of the ICMEs do not evolve like this and propagate in interplanetary … WebIf the interest is in the geoeffectiveness of the CME, B z is of particular importance. Figure 15 shows a comparison of some CME propagation properties. In the upper left panel, it can be seen that the stand-off distance is much lower for the higher resolution normal simulations compared to the low resolution simulation. The high resolution ...
WebWe compute the magnetic flux and helicity of an interplanetary flux tube observed by the spacecraft Wind on 24–25 October 1995. We investigate how model-dependent are the results by determining the flux-tube orientation using two different methods (minimum variance and a simultaneous fit), and three different models: a linear force-free field, a … WebGeoeffective definition: Capable of causing a geomagnetic disturbance. .
WebThe Sun's activity drives the variability of geospace (i.e., near-Earth environment). Observations show that the ejection of plasma from the Sun, called coronal mass ejections (CMEs), are the major cause of geomagnetic storms. This global-scale solar dynamical feature of coronal mass ejection was discovered almost three decades ago by the use of …
