Solar wind-magnetosphere coupling efficiency during ejecta and sheath-driven geomagnetic storms
We have investigated the effect of key solar wind driving parameters on solar wind-magnetosphere coupling efficiency during sheath and magnetic cloud-driven storms. The particular focus of the study was on the coupling efficiency dependence with Alfvén Mach number (MA). The efficiency has been estimated using the dawn-dusk component of the interplanetary electric field (EY ), Newell and Borovsk...
متن کاملSolar wind-magnetosphere coupling functions on timescales of 1 day to 1 year
There are no direct observational methods for determining the total rate at which energy is extracted from the solar wind by the magnetosphere. In the absence of such a direct measurement, alternative means of estimating the energy available to drive the magnetospheric system have been developed using different ionospheric and magnetospheric indices as proxies for energy consumption and dissipa...

15 صفحه اولDependence of plasma sheet energy fluxes and currents on solar wind-magnetosphere coupling
[1] The epsilon solar wind-magnetosphere coupling function was used to estimate the rate at which energy from the solar wind was being dissipated in the inner magnetosphere and ionosphere. The Geotail CPI ion and electron data sets showed that the average percentage of this energy that was carried earthward by energetic particles at |z| < 2.5 RE in the central plasma sheet increased from approx...
متن کاملAnalysis of the Bi-modal Nature of Solar Wind { Magnetosphere Coupling
It has been shown that the optimal linear prediction lter relating the solar wind electric eld and the geomagnetic activity, as measured by the AL index, is both bi-modal and dependent on the level of activity in the magnetosphere. Further studies truncated the prediction lter to a ve parameter model containing two low-pass ltered delta functions of arbitrary amplitude and delay time. The prese...
