Wildfires have been increasing in the American West over the past several decades, which has resulted in extreme public safety and economic problems. The conditions that lead to significant wildfires are generally known to be high temperature and low moisture. However, there is still uncertainty about how these conditions form, as studies show that the large-scale circulations cannot explain the strength of the heat and drought in mountainous terrain. This conference will bring together scientific experts on various topics to discuss the role of different aspects of meteorology on setting the conditions for major wildfires in complex terrain. In addition to the downstream societal impact of better forecasting conditions for wildfires, the conference will allow students and early-career researchers the opportunity to network and learn from leaders in the field.The University of California – Los Angeles will host a two-day workshop titled “Interaction between wildfire, heatwave, clouds and precipitation over complex topography” in Spring 2023. The goal of the workshop is to identify the key science questions and gaps of knowledge, to review current observational and modeling capability, and to assess feasibility of a potential field campaign to clarify the key processes behind the interaction between wildfire, heatwave, clouds and precipitation over complex topography. Specific topics will include: 1) Biomass burning aerosol-cloud-precipitation interaction and its potential role in amplifying heatwaves and dry spells, 2) Land-atmospheric interaction and its role in amplifying fire weather over complex topography, and 3) The influence of clouds and aerosols on radiative energy over complex topography. The conference plan is for in-person and remote participation.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.

在过去的几十年中，美国西部的野火一直在增加，这导致了极端的公共安全和经济问题。通常已知导致明显的野火的条件是高温和低水分。但是，这些条件如何形成仍然存在不确定性，因为研究表明，大规模循环无法解释山区的热量和干旱的强度。这次会议将汇集各种主题的科学专家，讨论气象各个方面在设定复杂地形主要野火条件下的作用。除了对野火更好的预测条件的下游社会影响外，会议还将使学生和早期研究人员有机会向该领域的领导者进行网络和学习。加利福尼亚大学 - 洛杉矶分校将举办为期两天的研讨会，标题为“野生火灾，云，云，云和危险的互动之间的相互作用”，该互动是在野外，云，云和危险中识别春季202春季的问题。回顾当前的观察和建模能力，并评估潜在的现场运动的可行性，以阐明复杂地形上野火，热浪，云和降水之间相互作用的关键过程。具体主题将包括：1）生物质燃烧气溶胶 - 云 - 云 - 云 - 卷曲的相互作用及其在放大热浪和干咒中的潜在作用，2）2）陆地大气相互作用及其在复杂地形上放大火灾天气中的作用，以及3）3））云和气溶胶对复杂的超图像上的云和气溶胶的影响。会议计划是针对面对面和远程参与的。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估值得支持。
