Turbulent mixing processes in deep alpine Lake Garda (I) have not extensively been observed. Knowledge about drivers of turbulent fluxes are important for insights in the transport of matter, nutrients and pollutants, in the lake and in natural water bodies in general. In this paper, the occurrence of internal wave induced turbulent convection, termed 'internally forced convection', is addressed as opposed to the more common shear-induced turbulence in a density stratified environment. Observations are analyzed from a dedicated yearlong mooring holding 100 high-resolution temperature sensors at 1.5 m intervals under a single current meter in the deeper half of the 344 m deep lake-center. Episodically, the weakly density stratified waters in the lower 50 m above the lake-floor show spectral slope and coherence evidence of short-term (15–30 min) convective motions under internal waves that are supported by the stronger stratified waters above. The near-homogeneous conditions are not attributable to frictional Ekman dynamics, but to large-scale internal wave crests.

在深高山加尔达湖（I）中湍流混合过程尚未广泛观察到。有关湍流通量驱动器的知识对于洞察物质，营养物质和污染物，在湖泊和整个自然水体中的运输至关重要。在本文中，解决了内部波引起的湍流对流（称为“内部强迫对流”）的发生，这与密度分层环境中更常见的剪切引起的湍流相反。在344 m深湖中心深处的一个电流表下，在一个单独的电流表下，以1.5 m的间隔固定100个高分辨率温度传感器，进行了为期一年的专用系泊分析。有趣地，在湖底以上50 m处的较弱密度分层水域显示出在内部波浪作用下短期（15–30 min）对流运动的频谱斜率和相干性证据，而内部波浪受上面较强的分层水域的支持。接近均质的条件不是归因于埃克曼摩擦动力学，而是归因于大型内部波峰。
