This project will help the research team understand the impacts of urbanization on weather and climate. It will provide valuable insights into how cities can influence our local environment and the importance of sustainable practices in urban planning. To do this, the project will develop a weather and urban model that examines the interaction between the urban heat island, outdoor water, and air pollution. This model will provide understanding of how cities and their excess heat, vegetation irrigations and resuspended pollution particles can affect cloud formation, especially rainfall and storms. The project will focus on the city of Houston, where data collected during recent field campaigns, led by the Department of Energy and National Science Foundation, have the potential to improve weather and urban models. By looking at various weather scenarios and factors, the research communities can get a more complete picture of the complex relationship between cities and weather. This new knowledge will also help improve climate adaptation and mitigation strategies and provide better support to urban communities and decision-makers.This project targets at improving the fundamental understanding of the physics tied to how the urban environment modulates meteorology, including convection and precipitation. It addresses issues of multiscale atmospheric interactions, associating synoptic scale and mesoscale forcing with urban resolving processes in the Houston area. The use of new observationally based products from the DOE/ASR Tracking Aerosol Convection interactions ExpeRiment (TRACER) and NSF/Experiment of Sea Breeze Convection, Aerosols, Precipitation and Environment (ESCAPE), together with an Urban Modeling Systems that includes a newly developed urban irrigation module, cutting-edge urban-resolving, cloud-resolving, and aerosol-aware modeling, will provide a more complete and detailed characterization of the impacts of urbanization on meteorology. To gain a more general physical understanding of the key factors and processes involved this project will examine the range of behaviors under different synoptic settings. Research scientist from the Desert Research Institute, the Pacific Northwest National Laboratory, and the University of Houston will collaborate to develop the outlined urban modeling systems and enhance understanding of urbanization's impact on warm cloud-aerosol interactions.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.

该项目将帮助研究团队了解城市化对天气和气候的影响。它将为城市如何影响我们的当地环境以及可持续实践在城市规划中的重要性提供宝贵的见解。为此，该项目将开发出一种天气和城市模式，以检查城市热岛，室外水和空气污染之间的相互作用。该模型将对城市及其多余的热量，植被灌溉和重悬的污染颗粒如何影响云形成，尤其是降雨和暴风雨。该项目将集中在休斯敦市，在该城市的近期现场活动中收集的数据由能源和国家科学系基金会领导，有可能改善天气和城市模型。 通过查看各种天气情况和因素，研究社区可以更完整地了解城市与天气之间的复杂关系。 这些新知识还将有助于改善气候适应和缓解策略，并为城市社区和决策者提供更好的支持。该项目的目标是提高对与城市环境如何调节气象相关的物理学的基本了解，包括对流和降水。它解决了多阶段大气相互作用的问题，将概要量表和中尺度强迫与休斯顿地区的城市解决过程相关联。使用来自DOE/ASR跟踪气溶胶对流相互作用实验（Tracer）和NSF/海风对流对流，气溶胶，降水和环境（逃生）的新型基于观察的产品的使用，以及一个包括新开发的城市灌溉模块，尖端的城市范围，云隔离，以及云的范围，以及一个新的型号，以及一个新型的云隔离，以及一个新的型号，以及一个新的型号，以及一个详细范围，以及一个详细的杂物，以及遍布型号的杂物，以及一个新近开发的城市建模系统，以及城市化对气象学的影响。 为了获得对涉及的关键因素和过程的更一般的物理理解，该项目将检查不同的概要设置下的行为范围。 沙漠研究所，太平洋西北国家实验室和休斯顿大学的研究科学家将合作开发概述的城市建模系统，并增强对城市化对温暖的云 - 大赛相互作用的影响的理解。该奖项反映了NSF的法规使命，并认为通过基金会的知识优点和广泛的范围来评估，并值得通过评估来进行评估。
