标题： Cosmological analogies for geophysical flows, Lagrangians, and new analogue gravity systems

摘要： 普通微分方程描述的地理流与弗里德曼宇宙学之间的形式类比被发展出来。 结果，得到了这些方程的拉格朗日和哈密顿形式，而旨在测试地理流的实验室实验被证明构成了宇宙学的类比引力系统。 显示英文摘要

摘要： Formal analogies between the ordinary differential equations describing geophysical flows and Friedmann cosmology are developed. As a result, one obtains Lagrangian and Hamiltonian formulations of these equations, while laboratory experiments aimed at testing geophysical flows are shown to constitute analogue gravity systems for cosmology.
