多尺度不稳定性在大气和海洋流动中普遍存在，是地球物理流体力学教学中的重要课题。然而，这些主题往往很难教授，对初学者来说也是违反直觉的。在本文中，我们介绍我们最先进的DIYNAMICS DIY YOYS Dynamic(DIYnamics)LEGO®机器人工具包，它允许用户创建桌面地球物理流模型。通过三个实验-垂直对流、热风流动和斜压不稳定-来模拟深海对流过程，以展示我们的工具包的强大的多尺度模拟能力。提供了详细的食谱，允许用户重现这些实验。此外，染料可视化测量表明，台面实验结果与理论完全一致。总而言之，我们的DIYDynamics设置为学生和教育工作者提供了一个可访问的桌面框架，用于对典型地球物理流动(如深海对流)中固有的多尺度行为进行建模。
Multi-scale instabilities are ubiquitous in atmospheric and oceanic flows and are essential topics in teaching geophysical fluid dynamics. Yet these topics are often difficult to teach and counter-intuitive to new learners. In this paper, we introduce our state-of-the-art Do-It Yourself Dynamics (DIYnamics) LEGO® robotics kit that allows users to create table-top models of geophysical flows. Deep ocean convection processes are simulated via three experiments – upright convection, thermal wind flows, and baroclinic instability – in order to demonstrate the robust multi-scale modeling capabilities of our kit. Detailed recipes are provided to allow users to reproduce these experiments. Further, dye-visualization measurements show that the table-top experimental results adequately agree with theory. In sum, our DIYnamics setup provides students and educators with an accessible table-top framework by which to model the multi-scale behaviors, inherent in canonical geophysical flows, such as deep ocean convection.
