摘要

摘要介绍了贝加尔湖秋季热压带深层对流过程的数值模拟结果。以深度较大的博尔达科夫河-马洛耶莫尔海峡断面为例，对各种风力条件下的时空温度分布进行了分析。模拟结果表明，风仅在 250 米的上层有效。然而，热压条产生的凸起不稳定性会导致深度达 \({\sim}600\) m 的对流混合。

Wind Effects on Deep Convection in Lake Baikal during the Autumnal Thermal Bar

The results of numerical modelling of deep convection processes in Lake Baikal during the autumnal thermal bar are presented. Using the Boldakov River—the Maloye More Strait cross-section, characterized by great depths, as an example, an analysis of the space–time temperature distributions under various wind conditions was conducted. Simulations have shown the effectiveness of wind only in the upper 250-meter layer. However, the cabbeling instability generated by the thermal bar can lead to convective mixing down to depths of \({\sim}600\) m.
