In the NW part of the Romania, there are geological conditions that allow to geothermal phenomena to manifest on the surface of the Earth. The limited exploitation of this energy resource is still limited by existing technologies and by the high cost of deep-water equipment. For a good image of the Romania's geothermal potential, we present, in our paper, the temperature map at 3000 m deep and the geothermal flow map on the surface. These maps were made with the Surfer program, based on the data obtained through d...

Geomagnetic data used for the study of the large periodicities of the geomagnetic field are presented as a series of hourly averages covering two solar cycles. These data were downloaded from the ftp site of the World Data Center for Geomagnetism from Kyoto. These data were calculated annually based on final data both from analogue magnetograms and digital recordings. To study the diurnal variations, non-periodic variations (geomagnetic storms, phenomena SSC or SFE) were used as one-minute averages, recorded in Su...

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 th...
