Substances that make up the Earth's atmosphere, oceans, and some interior areas are all seen to rotate. Scientists also see the same actions in the Sun, the other smaller and larger planets in our Solar System, as well as in other stars and planets found orbiting other stars. Rotation clearly affects the spread of heat, chemical compositions, and physical processes. It can drive circulation on the large scales we see from planets to stars. The "Rotating Convection: from the Lab to the Stars" meeting will bring together an international group of people who study different aspects of rotating convection to review the current state of this field, and plan future studies. The conference will last five days and have talks and posters mixed with group discussions. This conference will serve the national interest by promoting the progress of science when plans are made to coordinate future scientific studies of rotating convection to be most productive. Funding will support the travel of early-career participants from the United States.Rotation directly influences convection by affecting the transport rates of heat, chemical species, and angular momentum. It can therefore drive large-scale circulations, and large-scale inhomogeneities. The interaction of rotation and convection is complex and takes different forms depending on the parameter regime considered (e.g. high momentum/heat transfer oceanic convection compared to intermediate atmospheric and planetary convection, to low stellar convection). Understanding the complexity of fluid motions that derive from this interaction is a longstanding problem that can only be studied through a combination of experimental, numerical, mathematical and observational research. The principal goal of this workshop is to identify fundamental questions to be addressed in rotating convection research, and develop a research agenda for the future.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

构成地球大气、海洋和一些内部区域的物质都在旋转。科学家们在太阳、太阳系中其他大小行星以及其他恒星和围绕其他恒星运行的行星上也看到了同样的现象。旋转明显地影响着热量的传播、化学成分和物理过程。它可以驱动从行星到恒星的大尺度循环。“旋转对流：从实验室到恒星”会议将汇集一个研究旋转对流不同方面的国际小组，以回顾该领域的现状，并计划未来的研究。会议将持续5天，将有演讲、海报和小组讨论。这次会议将通过促进科学进步来服务于国家利益，当制定计划以协调未来对旋转对流的科学研究以取得最大成果时。资金将用于支持来自美国的早期职业参与者的旅行。旋转通过影响热量、化学物质和角动量的传输速率直接影响对流。因此，它可以驱动大规模的循环和大规模的非均质性。旋转和对流的相互作用是复杂的，并根据所考虑的参数制度采取不同的形式（例如，与中等大气和行星对流相比，高动量/热传递的海洋对流，低恒星对流）。理解由这种相互作用产生的流体运动的复杂性是一个长期存在的问题，只能通过实验、数值、数学和观察研究的结合来研究。本次研讨会的主要目标是确定旋转对流研究中需要解决的基本问题，并制定未来的研究议程。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
