Workshop on Future Storm-Resolving Configurations of Community Earth System Model (CESM); Fort Collins, Colorado; Two days in April 2023

该奖项支持一个主题为全球风暴解决配置的研讨会，该主题为共同体地球系统模式(CESM)。CESM包括地球气候系统的完整表示，包括大气、海洋、陆地表面、海冰和冰盖的组件模型。像CESM这样的地球系统模型在网格上模拟风、温度、湿度和其他大气变量，其中网格间距太粗(通常至少15公里)，无法模拟对流，这意味着在雷暴中可以看到颠覆的大气运动。虽然很难模拟整个对流运动范围，但网格间距为几公里(比如3公里)的模式能够模拟中尺度对流系统(MCSs)的演变，MCSs是发生在美国中部和世界其他地区的大雷暴系统。因此，人们有兴趣开发具有必要的高分辨率和增强的动力学和物理学所需的CESM配置，以便能够模拟MCS和其他形式的有组织对流。研讨会汇集了对这种配置的开发和使用感兴趣的模型开发人员和用户。研讨会的更广泛影响来自对能够更好地表示对人类活动有重大影响的天气和气候过程的模型的期望。例如，美国的大部分极端降水来自MCSs，它也是冰雹和龙卷风爆发的原因。更具体地说，讲习班使CESM的广大用户和开发人员受益，CESM是由全球气候研究界开发的唯一地球系统，也是为其开发的唯一地球系统。该奖项的资金将用于资助参加会议的学生和早期科学家的旅费。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award supports a workshop on the topic of global storm resolving configurations of the Community Earth System Model (CESM). CESM includes a full representation of the earth's climate system, including component models for the atmosphere, ocean, land surface, sea ice, and ice sheets. Earth system models like CESM simulate wind, temperature, humidity, and other atmospheric variables on grids in which the grid spacing is too coarse (generally at least 15km) to simulate convection, meaning the overturning atmospheric motions seen in thunderstorms. While it is very difficult to simulate the full range of convective motions, models with grid spacings of a few kilometers (say 3km) are able to simulate the evolution of mesoscale convective systems (MCSs), the large thunderstorm systems that occur over the central US and in other parts of the world. Thus there is interest in developing configurations of CESM with the necessary high resolution and enhanced dynamics and physics required to enable simulation of MCSs and other forms of organized convection. The workshop brings together model developers and users who are interested in the development and use of such configurations.The broader impacts of the workshop come from the desirability of models which are better able to represent weather and climate processes that have substantial impacts on human activities. For instance much of the extreme precipitation in the US comes from MCSs, which are also responsible for hailstorms and tornado outbreaks. More specifically, the workshop benefits the broad community of users and developers of CESM, which is the only earth system developed by and for the global climate research community. Funds from this award will support travel expenses for students and early-career scientists attending the meeting.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.
