Abstract
The results of mathematical simulation of biogeochemical processes during the autumn cooling of the lake are presented. The influence of wind on the distribution of phyto- and zooplankton, nitrate, ammonium, and phosphate nutrients is studied during the existence of the autumnal thermal bar in Barguzin Bay of Lake Baikal. Numerical simulations show the autumnal thermal bar in combination with the effect of western winds, which act opposite to the thermal front direction, to significantly slow down the transport of plankton biomass toward the central part of the bay.
