Automatic Detection of Geomagnetic Sudden Commencement Using Lifting Wavelet Filters

This paper proposes a method for detecting geomagnetic sudden commencement (SC) from a geomagnetic horizontal (H) component b y using lifting wavelet lters. Lifting wavelet lters are biorthog-onal wavelet lers containing free parameters. Our method is to learn such free parameters based on some training signals which c o n tain the SC. The learnt w avelet lters have the feature of training sign...

Pressure Balance between Solar Wind and Magnetosphere

An evaluation of the subsolar pressure balance between the solar wind and the geomagnetic field shows that the average proton density of the quiet-day solar wind (300-400 km/sec) should be between 6 and 10 p/cm a. Even during storm times the proton density should always be between 2 p/cm 3 and 70 p/cm 3. The relation between the interplanetary solar-wind parameters and the stagnation pressure i...

Effects on SuperDARN HF radar echoes of sudden impulses of solar wind dynamic pressure

In this work we perform a statistical analysis of the ionospheric echo response observed by six radars of the SuperDARN network in the Northern Hemisphere, over 236 Sudden Impulses (SI) of solar wind dynamic pressure events (from 1997 through 2000). For that purpose, we make use of MRS, the Mean Rate of Scattering, as a function of time during the SI event. We classify the events in sudden incr...

The driving mechanisms of particle precipitation during the moderate geomagnetic storm of 7 January 2005

The arrival of an interplanetary coronal mass ejection (ICME) triggered a sudden storm commencement (SSC) at ∼09:22 UT on the 7 January 2005. The ICME followed a quiet period in the solar wind and interplanetary magnetic field (IMF). We present global scale observations of energetic electron precipitation during the moderate geomagnetic storm driven by the ICME. Energetic electron precipitation...
