AGS-FIRP Track 1: Learning by Doing: Observing the Lake Michigan Lake-Breeze Circulation

在这项拟议的工作中，PI将部署威斯康星大学麦迪逊空间科学与工程中心（SSEC）便携式大气研究中心（SSEC）沿着相关仪器，从2024年4月29日到2024年5月10日，为了观察密歇根湖湖微风环流，用于威斯康星大学密尔沃基分校中尺度气象学学生的学期项目。威斯康星大学密尔沃基分校的研究船Neeskay将在密歇根湖进行为期一天的同步观测。本科生将在课堂上使用新的观察结果，七年级的教室将获得实践经验的观察，并将组织一个开放的房子，以吸引更广泛的公众。这些设施将用于收集数据，以测试两个假设：（1）在─直接邻近密歇根湖的表面湖风热力学特征与密歇根湖上的对应物没有显著差异，湖风环流前沿沿着的水平和垂直温度和密度梯度在湖风季节早期比在季节高峰期有较大的幅度，这是因为密歇根湖和邻近陆块之间的气候温差较大。拟议的研究将使本科大气科学专业的学生有机会发展新的理解，并产生自己的湖风环流概念模型，并将理论从课堂应用到观测研究中。此外，该项目将涉及三个七年级的科学班从密尔沃基公立学校在实践活动与学生。最后，开放日将促进更广泛的公众参与大气观测和区域天气和气候。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估。

The PI in this proposed work will deploy the University of Wisconsin-Madison Space Science and Engineering Center (SSEC) Portable Atmospheric Research Center (SPARC) along with the associated instrumentation from April 29, 2024, through May 10, 2024, in order to observe the Lake Michigan lake-breeze circulations for term projects for mesoscale meteorology students at the University of Wisconsin-Milwaukee. Concurrent observations will be taken for a single day by University of Wisconsin-Milwaukee Research Vessel Neeskay which will be deployed in Lake Michigan. Undergraduate students will use the new observations in the classroom, seventh-grade classrooms will gain hands-on experience with the SPARC, and an open house will be organized to engage the broader public.These facilities will be used to collect data to test two hypotheses: (1) near-surface lake breeze thermodynamic characteristics immediately adjacent to Lake Michigan are not significantly different from their counterparts over Lake Michigan owing to the short residence time of the lake-influenced airmass over land and (2) horizontal and vertical temperature and density gradients along the leading edge of the lake-breeze circulation have greater magnitudes early in the lake-breeze season than they do during the season’s peak because of the climatologically greater temperature differential between Lake Michigan and adjacent land masses. The proposed research will allow undergraduate atmospheric science majors the opportunity to develop new understanding and generate their own conceptual models of lake-breeze circulations and to apply theories from the classroom to observational research. Further, the project will involve three seventh-grade science classes from Milwaukee Public Schools in hands-on activities with the SPARC. Finally, an open house will facilitate broader public engagement with atmospheric observation and regional weather and climate.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.
