Abstract

The continuous development of data acquisition and processing techniques in planetary geomagnetic observatories and satellite data, allows at this time to extract as complete information about the morphology and evolution over time of the terrestrial geomagnetic field. The Sun, the source of all energy on Earth, heat the planet and drive the motions of atmosphere. The brightness of the Sun with 11-years solar cycles with 0.1% variation may be explaining the major driving changes in weather patterns on Earth. At the same time, solar activity is the only cause of the Earth's external geomagnetic variations. In the paper we did a study on a period of four solar cycles, regarding the correlation mode of the solar activity, the geomagnetic variations recorded in the Surlari Geomagnetic Observatory and the climatic data available from external sources. The techniques used in this study use algorithms for spectral and wavelet analysis, phenomenological extrapolation and comparative analysis between parameters. The geomagnetic data used in this study are the hourly averages during 1962-2006, as well as the calculated indices regarding the geomagnetic activity corroborated with the climatic data.
