The researchers will plan and conduct a physical experiment specifically to verify numerical predictions of the coalescence of turbulent vorticity fluctuations into a single, large, strongly stable, coherent vortex structure. Laboratory verification of the formation of such a structure, and associated efforts to understand and predict conditions for its occurrence, are of importance to atmospheric and oceanographic long-lived eddy structures embedded in an otherwise turbulent flow.

研究人员将专门计划和进行一项物理实验，以验证湍流涡度涨落合并为单一、大、强稳定、一致的涡旋结构的数值预测。对这种结构的形成进行实验室验证，以及为了解和预测其发生的条件所作的相关努力，对于嵌入在其他湍流中的大气和海洋长期涡旋结构是重要的。
