Abstract
The modern science determines and intensively studies multiple negative effects of space environment influence on the objects of the national economy that are most clearly discovered in periods of the so-called magnetic storms. At the same time, although some scientific papers are concerned with options for graphical depicting of the geomagnetic field of intraterrestrial sources, the issue of informative visualization of geomagnetic variations is still open. The paper is concerned with the approach to geomagnetic variations visualization in time-frequency domain of information signal based on discrete wavelet transformation. Also the authors describe and analyze results of visualization of solar-diurnal, annual, seasonal, 11-year and secular variations of geomagnetic field, as well as variations, inherently related to the direct impact of solar corpuscular streams on the Earth's magnetosphere.
Keywords: scientific visualization, geomagnetic field, magnetosphere, geomagnetic variations, wavelet transformation.
