Although less than 1% of the World’s land cover is urbanized, more than half of the World’s total population reside in urbanized areas and nearly 75% of energy is consumed here. Hence understanding the energetic and dynamic interactions in the urban boundary layer is germane to issues related to human health, climate change, air quality and current & future energy sustainability. The three dimensionality and the large scale heterogeneity in physical and hygro-thermal properties of the built environment pose a considerable challenge to sensing and modeling the exchanges of momentum, mass and energy over urban areas. This talk will focus on some of the experimental and modeling work done in this area and will particularly highlight the role played by built surfaces in modifying the surface energy budget and its influence on the transport of scalars in the surface layer. The talk will also focus on the role played by local scale models that account for sub-facet level heterogeneity in capturing the urban energetic interactions. Finally the talk will summarize how these advances made through experimental and local scale models improve large scale numerical models that are overwhelmingly used in weather prediction and regional & global climate studies.

Bio

Prathap Ramamurthy is an Associate Research Scholar at Princeton University. His research primarily focuses on understanding the surface to atmosphere interactions over urban areas. He obtained his PhD in Mechanical Engineering from University of Utah in 2011 and his thesis deliberated on the complexity in the transport of carbon dioxide and surface energy fluxes over a highly vegetated suburban neighborhood.
