The effects of urban heat islands (UHIs) have a substantial bearing on the sustainability cities and environs. This paper examines efficacy green cool roofs as potential UHI mitigation strategies to make more resilient against UHI. We employed urbanized version Weather Research Forecasting (uWRF) model at high (1 km) resolution with physically-based rooftop parameterization schemes (conventional, cool), first-time application Chicago metropolitan area. simulated hot summer period (16–18...
Abstract Emerging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific societal interest mountain meteorology. To address needs help improve the prediction weather, U.S. Department Defense has funded a research effort—the Mountain Terrain Atmospheric Modeling Observations (MATERHORN) Program—that draws expertise multidisciplinary, multi-institutional, multinational group researchers. The...
Abstract Air–Sea Interactions in the Northern Indian Ocean (ASIRI) is an international research effort (2013–17) aimed at understanding and quantifying coupled atmosphere–ocean dynamics of Bay Bengal (BoB) with relevance to monsoons. Working collaboratively, more than 20 institutions are acquiring field observations operational high-resolution models address scientific issues that have stymied monsoon predictability. ASIRI combines new mature observational technologies resolve submesoscale...
Abstract The interaction of global climate change and urban heat islands (UHI) is expected to have far-reaching impacts on the sustainability world’s rapidly growing population centers. Given that a wide range spatiotemporal scales contributed by meteorological forcing complex surface heterogeneity complicates UHI, multimodel nested approach used in this paper study climate-change Chicago, Illinois, covering relevant scales. One-way dynamical downscaling with model chain consisting...
The Arabian Sea circulation is forced by strong monsoonal winds and characterized vigorous seasonally reversing currents, extreme differences in sea surface salinity, localized substantial upwelling, widespread submesoscale thermohaline structures. Its complicated temperature patterns are important for the onset evolution of Asian monsoon. This article describes a program that aims to elucidate role upper-ocean processes atmospheric feedbacks setting properties region. wide range spatial...
Over the past half century, burgeoning urban areas such as Chicago have experienced elevated anthropogenic-induced alteration of local climates within urbanized regions. As a result, heat island (UHI) effect in these has intensified. Global climate change can further modulate UHI’s negative effects on human welfare and energy conservation. Various numerical models exist to understand, monitor, predict UHI its ramifications, but none resolve all relevant physical phenomena that span wide...
Chemical plume detection and modeling in complex terrain present numerous challenges. We experimental results from outdoor releases of two chemical tracers (sulfur hexafluoride Freon-152a) different locations mountainous terrain. plumes were detected using standoff instruments collocated at a distance 1.5 km the releases. A passive long-wave infrared hyperspectral imaging system was used to show time- space-resolved transport regions near source. An active swept-wavelength external cavity...
Abstract. Growth in adoption of distributed wind turbines for energy generation is significantly impacted by challenges associated with siting and accurate estimation the resource. Small turbines, at hub heights 40 m or less, are greatly terrestrial obstacles such as built structures vegetation that can cause complex wake effects. While some progress high-fidelity fluid dynamics (CFD) models has increased potential accuracy modelling impacts on turbulent flow, these too computationally...
This report describes eighteen projects that explored how commercial cloud computing services can be utilized for scientific computation at national laboratories. These demonstrations ranged from deploying proprietary software in a environment to leveraging established cloud-based analytics workflows processing datasets. By and large, the were successful collectively they suggest valuable computational resource
