The goal is to understand atmospheric impact on people's health and comfort due to elements such as wind and airborne particle flow, dispersal and transport. Think of it as the physics of comfort. Dr. Fernando puts it this way: "The urban boundary layer of the atmosphere is where people live. And the long term-viability of cities and our ability to assure a high quality of urban life is affected by how clean our environment is and how fast it is changing by human impacts."
Dr. Fernando's team used fluid mechanics to understand flow and help devise mathematic models to predict periods of high particulate pollution that affect human health and periods of extreme temperature impacting human comfort. Explains Dr. Fernando, who also is an emeritus professor at Arizona State University: "Our team started applying fluid dynamic analysis in a rapid urban growth situation of Phoenix because it is a useful test bed for developing an understanding of complex processes. We then built models to provide a basis for sound growth policy. Even though they must be further validated in the field, now policy and decision makers come to us for guidance. It's been very encouraging, because we want our cities and their residents to flourish."

ABOUT Physics of Fluids
Physics of Fluids is published by the American Institute of Physics with the cooperation of The American Physical Society Division of Fluid Dynamics. The journal is devoted to the publication of original theoretical, computational, and experimental contributions to the dynamics of gases, liquids, and complex or multiphase fluids. Content is published online daily and collected into monthly online and printed issues (12 issues per year). See: http://pof.aip.org/
The American Institute of Physics is a federation of 10 physical science societies representing more than 135,000 scientists, engineers, and educators and is one of the world's largest publishers of scientific information in the physical sciences. Offering partnership solutions for scientific societies and for similar organizations in science and engineering, AIP is a leader in the field of electronic publishing of scholarly journals. AIP publishes 12 journals (some of which are the most highly cited in their respective fields), two magazines, including its flagship publication Physics Today; and the AIP Conference Proceedings series. Its online publishing platform Scitation hosts nearly two million articles from more than 185 scholarly journals and other publications of 28 learned society publishers.
