Paper Abstract

The effect of weak solar activity generated disturbances on the ecological system has been investigated. The study is based on simulation of the tundra community `vegetation/lemmings/polar foxes'. The model was verified using the data on the West Taimir ecosystem. The summer duration determined from meteorological indices was taken as the input parameter of the model. If the effect was small enough in amplitude, the model demonstrated 3-year-long intervals between the maxima modulated by the 11-year-cycle. At the second stage of our study we used the real series of summer duration (from setting in to melting of the snow cover) in the region under consideration. When the real summer duration was included in the model, the spectrum displayed an 11-year component that was nearly as pronounced as the observed one. Since the data on summer duration used in the model were taken directly from meteorological stations without processing, the appearance of the 11-year periodicity in the model dynamics may be regarded as additional evidence for dependence of the meteorological series on solar activity.
