Forecasting geomagnetic activity three hours in advance for ionospheric applications
Geomagnetic activity ionospheric disturbance ferecasting
2015/9/28
An attempt at forecasting the magnetic activity index three hours in advance is presented. This approach is based on a suitable treatment of time-weighted accumulations of the three-hourly magnetic in...
Neural network prediction of geomagnetic activity:a method using local Hölder exponents
Neural network prediction geomagnetic activity local Hö lder exponents
2009/11/12
Local scaling and singularity properties of solar wind and geomagnetic time series were analysed using Hölder exponents . It was shown that in analysed cases due to the multifractality of fluctua...
Analysis of the geomagnetic activity of the Dst index and self-affine fractals using wavelet transforms
geomagnetic activity Dst index self-affine fractals wavelet transforms
2009/11/11
The geomagnetic activity of the Dst index is analyzed using wavelet transforms and it is shown that the Dst index possesses properties associated with self-affine fractals. For example, the power spec...
