Tropical forests around the world play a significant role in the regulation of regional and global climate systems. The Amazon rainforest is the greatest land-based global sink of greenhouse gases and the massive thunderstorm complexes that develop over the region transport moisture and energy that affect global circulation. Due to these factors, it is important to understand how the rainforest is changing in response to warmer conditions and extreme weather events. This travel award provides funding for US scientists to attend a meeting to collaborate with regional scientists on the current state and next steps for research projects aimed at better understanding the impact of climate on the Amazon rainforest and the subsequent global impacts. Included in the meeting will be Indigenous residents of the region who will share their traditional knowledge of observing and anticipating changes in weather and climate. Early career scientists from diverse backgrounds will assume leadership roles in organizing and prioritizing the workshop deliberations.The Amazon rainforest is experiencing unprecedented transformations in response to extreme climate change features such as accelerated warming, prolonged droughts, and biomass burning. The goals of the collaborative US/Brazil workshop are to summarize the state of the science, identify future research topics and methods, and forge partnerships between US and Brazilian scientists. The workshop will be planned around the following session topics:• Summarizing the occurrences of unusual weather events and extreme climate anomalies in the Amazon during the last 50 years and projected climate through 2050.• Examining the extent that climate change and land use shifts have recently contributed to modifying the water cycling in the Amazon Basin.• Discussing future field and numerical modeling studies to develop unified approaches to determine net ecosystem exchange for Amazonian regions with variable topography and for all relevant atmospheric stability conditions.• Identifying the emerging data assimilation methods for in-situ and satellite observations to generate improved analysis fields over the region and identifying the most suitable AI techniques to process large amounts of data related to the condition of the rainforest and its responses to climate-related events.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.

世界各地的热带森林在调节区域和全球气候系统方面发挥着重要作用，亚马逊雨林是全球最大的陆地温室气体汇，该地区形成的大规模雷暴复合体输送着影响全球的水分和能量。由于这些因素，了解热带雨林如何因气候变暖和极端天气事件而发生变化非常重要。该旅行奖为美国科学家提供资金参加会议，与地区科学家就当前状况和未来状况进行合作。旨在更好地开展研究项目的步骤了解气候对亚马逊雨林的影响以及随后的全球影响将包括该地区的土著居民，他们将分享他们观察和预测天气和气候变化的传统知识。亚马逊雨林正在经历前所未有的转变，以应对加速变暖、长期干旱和生物质燃烧等极端气候变化特征。美国/巴西合作研讨会的目标是总结现状。研讨会将围绕以下会议主题进行规划： • 总结过去 50 年来亚马逊地区异常天气事件和极端气候异常的发生情况。年和预计到 2050 年的气候。• 研究气候变化和土地利用变化最近对改变亚马逊流域水循环的影响程度。• 讨论未来的实地和数值模型研究，以开发确定净生态系统交换的统一方法适用于地形多变的亚马逊地区以及所有相关的大气稳定性条件。• 确定用于现场和卫星观测的新兴数据同化方法，以在该地区生成改进的分析场，并确定最合适的人工智能技术来处理大量相关数据该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
