The Urban Fluid Dynamics lab focuses on using fundamental principles in fluid dynamics to study the atmosphere over cities. Our lab focuses on both near-surface and mixed-layer processes within the urban boundary layer. Our research areas include turbulent transport in the UBL, convection and precipitation (1); urban heat island and surface energy budgets (2,3); building energy sustainability (4); multi-scale observations and smart sensing (5).
