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.

这项职业赠款的研究目标是建立一个物理框架，该框架解释了北半球（NH）夏季循环的水分运输作用，包括其变异性和未来变化。一个理论框架将开发通过亚热带反气旋，季风和斜压涡流到能量和动量运输以及一般循环的理论框架。该框架将用于1）使用理想化的数值模型模拟和2）创建基于过程的诊断来测试和了解NH夏季循环的动态相互作用，以验证在最先进的气候模型中NH夏季循环，并分析和解释循环的未来变化，对地球上的潮湿和地球上的湿区的含义以及对教育目标的材料进行了概念，以促进教学的概念。教育活动涉及与哥伦比亚中学（CSS）合作，有选择性的六至十二年级的标题1科学，工程和数学学校。这些活动将与哥伦比亚大学的夏季研究计划（CUSRP）协调，该计划是一项由NSF支持的计划。教育活动将1）与中学教师一起参与科学，该教师已被证明会对学生和其他老师产生积极影响，2）满足国家的需求，通过开发中学地球科学课程来教育公众关于气候变化科学的教育，该课程综合了统一的物理科学的天气和气候，并在统一的物理科学角度观察和3）鼓励未成年人的参与案例科学。
