title: [Model of "standing water" of Baikalian phytoplankton interannual dynamics].
abstract: A "standing waves" model is presented which is based on the idea that an energy impulse accumulated from the spring bloom outburst of phytoplankton moves along a food chains. When its "echo" comes back, it generates a new bloom outburst, and a next cycle occurs. It is supposed that the resonance of self-supporting oscillations in populations with periodic solar influences led to standing waves, which provide for biosystem stability and cyclic recurrence of phytoplankton bloom. To test the model, an analysis of the interannual dynamics (from 1941 to 1998) of the pelagic phytoplankton in the southern basin of the lake Baikal was carried out. The discovered 11-year cycles with 3 2/3-year cycles within them conform well to the model, which made it possible to explain not only the cyclic recurrence but also a number of other obscure aspects of phytoplankton life in the lake Baikal. The next bloom burst is predicted to take place in 2001.
