Investigating relevant turbulent processes at fundamental level is essential to understand geophysical flows in the atmosphere and oceans, and is critical for such varied purposes as weather forecasting, projecting climate change, and mitigating air pollution. Our current conceptual and technical tools are inadequate for explaining turbulence, and have yet to approach towards a comprehensive theory. Inadequate representation of interactions across multiple spatio-temporal scales in the atmosphere and oceans is one stumbling reason for poor performance of numerical models.

在基本水平上研究相关的湍流过程对于理解大气和海洋中的地球物理流动至关重要，并且对于天气预报、预测气候变化和减轻空气污染等各种目的至关重要。我们目前的概念和技术工具不足以解释湍流，而且还没有接近一个全面的理论。大气和海洋中跨多个时空尺度的相互作用的代表性不足是数值模式性能不佳的一个绊脚石。
