A correlation between variations in the medical parameters and the heliogeophysical indices describing physical processes during solar storms was established. It was proposed that one of the reasons for the biotropic effects observed is rheological shifts of human blood during enhancement of solar activity. The influence of heliogeophysical disturbances on the rheological properties of blood was investigated.

Geomagnetic effects on quantitative characteristics of alpha-rhythm were assessed by shifts in electroencephalograms recorded in 126 essentially healthy human subjects and changes in lipid metabolism in the cortex and white matter in 140 white rats. Indices of the geomagnetic activity were D, H and Z-components. The method of "epoch superposition" revealed an inconsistent alpha-rhythm depression and flattening out of the interhemispheric functional asymmetry against persistently high electrical activity in the right hemisphere, and biochemical asymmetry in consequence of different lipid transformation processes. Spotlighted were some nonspecific adaptive reactions to changes in the environment and stressful agents.

[Heliogeophysical factors and aviation accidents]. / Geliogeofizicheskie faktory i aviatsionnye proisshestviia.

It was shown by two independent methods that there is a certain correlation between the number of aviation accidents and heliogeophysical factors. The statistical and spectral analyses of time series of heliogeomagnetic factors and the number of aviation accidents in 1989-1995 showed that, of 216 accidents, 58% are related to sudden geomagnetic storms. A similar relation was revealed for aviation catastrophes (64% out of 86 accidents) and emergencies (54% out of 130 accidents) that coincided in time with heliogeomagnetic storms. General periodicities of the series were revealed by the method of spectral analysis, namely, cycles of 30, 42, 46, 64, 74, 83, 99, 115, 143, 169, 339 days, which confirms the causative relation between the number of aviation accidents and heliogeomagnetic factors. It is assumed that some aviation accidents that coincided in time with geomagnetic storms, are due to changes in professional abilities of pilots that were in the zone of storms.
