On the role of wind direction in the thermal bar dynamics in autumn: A numerical study

Abstract

The effect of wind direction on the dynamics of the thermal bar in autumn was studied in Barguzin Bay of Lake Baikal by numerical modeling. An analysis of the temperature fields simulated showed that wind direction was essential to thermal bar development and temperature distribution. Easterly wind, in contrast to westerly wind, contributed to increased speed of the surface propagation of the thermal bar toward the open lake. The results presented here also demonstrate that autumnal cooling of Barguzin Bay was faster during easterly wind activity.
