Solar Wind Parameters for Magnetospheric Magnetic Field Modeling
Magnetospheric magnetic field models are crucial for many space weather applications. However, the latest empirical models require solar wind and IMF data, which are not always available. Data gaps are especially common for times before the launch of the WIND spacecraft at the end of 1994, but even after then there are data gaps. We present a method to interpolate the solar wind characteristics...
متن کاملApril 2000 magnetic storm: Solar wind driver and magnetospheric response
[1] On 4 April 2000, a coronal mass ejection (CME) took place close to the western limb of the Sun. The shock front of the CME hit the Earth’s magnetosphere on 6 April. A strong interplanetary southward BZ event in the sheath region caused a magnetic storm that was the second strongest in the year 2000 if quantified by the peak of the Dst index. We have analyzed this sequence of events using ob...

متن کاملModeling magnetospheric current response to solar wind dynamic pressure enhancements during magnetic storms: 2. Application to different storm phases
[1] Two patterns of ground H perturbation as response to pressure enhancements during different phases of storms are found. One is polarity asymmetry under southward IMF Bz, e.g., 25 September 1998, 29 May 2003, and 10 January 1997 events; the other is positive H perturbation everywhere under northward IMF Bz, e.g., 7 November 2000 event. The polarity asymmetry can be further divided into two c...
متن کاملScaling and singularity characteristics of solar wind and magnetospheric fluctuations
Preliminary results are presented which suggest that scaling and singularity characteristics of solar wind and ground based magnetic fluctuations appear to be a significant component in the solar wind magnetosphere interaction processes. Of key importance is the intermittence of the ”magnetic turbulence” as seen in ground based and solar wind magnetic data. The methods used in this paper (estim...
