Mortalité et Nombre de Wolf

Mortalité et Ap Index

The special consideration shows that temperature fluctuations and other meteorological factors can not explain the mortality peaks The comparison of the mortality data with Wolf numbers (WN), see top panel of Fig.1, has showed a rather high level of correlation (k = 0.74± 0.21) for Ap index is presented on the bottom panel. It is a planetary magnetic index and shows the magnetic disturbance level between 46° and 63° north and south geomagnetic latitudes

In any case, the dependence of plant biological response on it physiological state was shown in relation to weak artificial EM fields effects [Kashulin, Pershakov, 1995]. We suggest that unidentified intermediate heliogeophysical factor is involved in the modulation of mortality process, and its variation matches making more to WN as compared to the magnetic disturbance index Ap
