| Resumo | When the interplanetary magnetic field carried by the solar wind opposes to the Earths intrinsic magnetic field, a substantial transfer of energy into the terrestrial magnetosphere takes place. If this condition persists for several hours, the magnetosphere becomes very disturbed. As a result at midto low latitudes a ring current starts to develop and at high latitudes ionospheric currents (electrojet and field-aligned currents) dominate. The ring current provides the geomagnetic conditions for magnetic storms to be settled down. Wavelet analysis is becoming a common tool since they allow the decomposition of data, functions or operators into different frequency or scale components. Accordingly, wavelet transforms seem to be good tools to "zoom in" short-lived high frequency phenomena such as discontinuities ("shocks") in signals and transient structures. In this work the remarkable ability of wavelets to highlight the singularities associated with discontinuities present in the horizontal component of the Earth magnetic field is explored. Magnetograms obtained at five magnetic stations for two geomagnetic storms have been analyzed by a Daubechies orthogonal wavelet transform decomposition. The wavelet coefficient magnitudes at three levels have been studied. In both cases, the physical discontinuities in the horizontal component of the geomagnetic field are clearly detected by means of these coefficients identifying the disturbed interval related to geomagnetic storms.Wavelet analysis has proved to be a useful tool in the identification of the geomagnetic storms just using nonprocessed data. |
