The research objective of this CAREER grant is to build a physical framework that explains the role of moisture transport in the Northern Hemisphere (NH) summer circulation, including its variability and future change. A theoretical framework connecting moisture transport by subtropical anticyclones, Monsoons and baroclinic eddies to energy and momentum transports and the general circulation will be developed. The framework will be used to 1) test and understand the dynamical interactions of the NH summer circulation using idealized numerical model simulations and 2) create process-based diagnostics to validate the NH summer circulation in state-of-the-art climate models and analyze and interpret projected future changes in the circulation and the implications for wet and dry regions on Earth.The educational objectives are to engage teachers in climate research and to incorporate physical concepts into secondary school earth science curriculum. The educational activities involve collaboration with Columbia Secondary School (CSS) a selective sixth- through twelfth-grade title 1 science, engineering and math school. The activities will be coordinated with Columbia University's Summer Research Program (CUSRP) for science teachers, an NSF supported program. The educational activities will 1) engage secondary school teachers in science, which has been shown to positively impact students and other teachers, 2) address a national need to educate the public about climate change science through the development of secondary school earth science curriculum that synthesizes weather and climate within a unifying physical science perspective and 3) encourage the participation of underrepresented minorities in climate science.

这项职业资助的研究目标是建立一个物理框架，解释水分输送在北半球（NH）夏季环流中的作用，包括其变异性和未来的变化。将建立一个理论框架，将副热带反气旋、季风和斜压涡流的水分输送与能量和动量输送以及大气环流联系起来。该框架将用于 1) 使用理想化数值模型模拟测试和了解北半球夏季环流的动态相互作用，2) 创建基于过程的诊断，以在最先进的气候模型中验证北半球夏季环流，并分析和解释预计的未来环流变化以及对地球潮湿和干燥地区的影响。教育目标是让教师参与气候研究，并将物理概念纳入中学地球科学课程。教育活动涉及与哥伦比亚中学 (CSS) 的合作，这是一所精选的六年级至十二年级科学、工程和数学一级学科学校。这些活动将与哥伦比亚大学科学教师夏季研究计划 (CUSRP) 协调，该计划是 NSF 支持的计划。这些教育活动将：1）让中学教师参与科学，这已被证明对学生和其他教师产生积极影响；2）通过开发中学地球科学课程，在统一的物理科学视角下综合天气和气候，满足国家对公众进行气候变化科学教育的需要；3）鼓励代表性不足的少数群体参与气候科学。
