Abstract Infrastructure-based heat reduction strategies can help cities adapt to high temperatures, but simulations of their cooling potential yield widely varying predictions. We systematically review 146 studies from 1987 2017 that conduct physically based numerical modelling urban air temperature resulting green-blue infrastructure and reflective materials. Studies are grouped into two scales: neighbourhood scale, building-resolving (i.e. microscale); city neighbourhood-resolving...
The potential for critical infrastructure failures during extreme weather events is rising. Major electrical grid failure or "blackout" in the United States, those with a duration of at least 1 h and impacting 50,000 more utility customers, increased by than 60% over most recent 5 year reporting period. When such blackout coincide time heat wave conditions, population exposures to both outside within buildings can reach dangerously high levels as mechanical air conditioning systems become...
The recent concurrence of electrical grid failure events in time with extreme temperatures is compounding the population health risks weather episodes. Here, we combine simulated heat exposure data during historical wave three large U.S. cities to assess degree which heat-related mortality and morbidity change response a concurrent event. We develop novel approach estimating individually experienced temperature approximate how personal-level changes on an hourly basis, accounting for both...
Compound dry-hot extreme (CDHE) events pose greater risks to the environment, society, and human health than their univariate counterparts. Here, we project decadal-length changes in frequency duration of CDHE for major U.S. cities during 21st century. Using Weather Research Forecasting (WRF) model coupled an urban canopy parameterization, find a considerable increase future across all under compound effect high-intensity GHG- development-induced warming. Our results indicate that while...
Abstract Atmospheric and surface urban heat islands (UHI) originate from common energetic processes, but the status of scientific knowledge on their time evolution is highly disparate. The diurnal cycles atmospheric UHI are well known based years continuous measurements in cities; UHI, however, cannot be measured continuously or situ. In this article, we aim to reconcile these differences. We begin with a synthesis previous work which leads novel historically minded approach research...
Abstract Utility-scale solar power plants are a rapidly growing component of the renewable energy sector. While most agree that can decrease greenhouse gas emissions, effects photovoltaic (PV) systems on surface exchanges and near-surface meteorology not well understood. This study presents data from two eddy covariance observational towers, placed within adjacent to utility-scale PV array in southern Arizona. The period (October 2017–July 2018) includes full range annual temperature...
We use a suite of decadal-length regional climate simulations to quantify potential changes in population-weighted heat and cold exposure 47 US metropolitan regions during the 21st century. Our results show that locally defined extreme (i.e., "population exposure") would increase by factor 12.7-29.5 under high-intensity greenhouse gas (GHG) emissions urban development pathway. Additionally, end-of-century population is projected rise 1.3-2.2, relative start-of-century exposure. identify...
Abstract Appropriately characterizing future changes in regional-scale precipitation requires assessment of the interactive effect owing to greenhouse gas-induced climate change and physical growth built environment. Here we use a suite medium resolution (20 km grid spacing) decadal scale simulations conducted with Weather Research Forecasting model coupled an urban canopy parameterization examine interplay between end-of-century long-lived gas (LLGHG) forcing expansion on continental US...
Abstract Dynamical downscaling provides physics-based high-resolution climate change projections across regional and local scales. This is particularly important for island nations characterized by complex terrain, where the coarse resolution of global model (GCM) output often prohibits direct use. One main motivations dynamical to reduce biases relative host GCM at scale, which can be quantified through assessing ‘added value’. However, added value from not guaranteed; quantifying this help...
Abstract In the US, more than 80% of fatal cases heat exposure are reported in urban areas. Notably, indoor is implicated nearly half such cases, and lack functioning air conditioning (AC) predominant cause overheating. For residents with limited capacity to purchase, maintain, operate an AC system, or during summertime power outages, ability buildings maintain safe thermal conditions without mechanical cooling primary protective factor against heat. this paper, we use whole-building energy...
Abstract Detection and attribution experiments are designed for the causal diagnosis of features in climate system, including trends mean extreme events. While several detection data sets now exist, coarse resolution models used (∼100‐km) often hinders their application to topographically complex regions like Aotearoa New Zealand small island nations. The atmospheric may also be detrimental simulating certain circulation, jets, blocking cyclones. To address this, here we introduce a new set...
Abstract The air temperature cooling impacts of infrastructure-based adaptation measures in expanding urban areas and under changing climatic conditions are not well understood. We present simulations conducted with the Weather Research Forecasting (WRF) model, coupled to a multi-layer model that explicitly resolves pedestrian-level conditions. Our dynamically downscale global climate projections, account for projected growth, examine extensive cool roof deployment Atlanta, Detroit, Phoenix...
Abstract Three ~12‐km reanalysis‐driven regional climate models (RCMs) are evaluated in terms of capturing climatologies and extremes precipitation, temperature surface wind over Aotearoa/New Zealand (NZ). NZ provides an excellent case study for evaluating high‐resolution RCMs due to its coastal complex terrain isolated geographical position the midlatitudes, exposed both tropical polar influences. Overall, we find that faithfully reproduce observed climate, with precipitation particularly...
Abstract. The adverse impacts of urban heat and global climate change are leading policymakers to consider green blue infrastructure (GBI) for mitigation benefits. Though many models exist evaluate the cooling GBI, their complexity computational demand leaves most them largely inaccessible those without specialist expertise computing facilities. Here a new model called Air-temperature Response Green/blue-infrastructure Evaluation Tool (TARGET) is presented. TARGET designed be efficient easy...
