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.

这项拟议工作的 PI 将在 2024 年 4 月 29 日至 2024 年 5 月 10 日期间部署威斯康星大学麦迪逊分校空间科学与工程中心 (SSEC) 便携式大气研究中心 (SPARC) 以及相关仪器，以便观测威斯康星大学密尔沃基分校中尺度气象学学生学期项目的密歇根湖湖风环流将由威斯康星大学密尔沃基分校进行一天的并发观测。将部署在密歇根湖的威斯康星-密尔沃基研究船 Neeskay 本科生将在课堂上使用新的观察结果，七年级课堂将获得 SPARC 的实践经验，并将组织开放日以吸引更广泛的人参与。这些设施将用于收集数据来检验两个假设：（1）由于密歇根湖的停留时间较短，紧邻密歇根湖的近地表湖风热力学特征与其在密歇根湖上空的位置没有显着差异。受影响的气团陆地上空和（2）沿湖风环流前缘的水平和垂直温度和密度梯度在湖风季节早期比季节高峰期间有更大的幅度，因为密歇根湖之间的气候温差更大拟议的研究将使大气科学专业的本科生有机会发展新的理解并生成自己的湖风环流概念模型，并将课堂理论应用于观测研究此外，该项目将涉及七分之三。年级科学课最后，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。该奖项是 NSF 的法定使命，并通过使用基金会的评估被认为值得支持。智力价值和更广泛的影响审查标准。
