Heat wave mitigation strategies for wine grape production and measures of the impact of heat on berry ripening and wine composition
… evidence and forecasted more intense and longer heatwaves requires that mitigation strategies be investigated that can reduce the high temperature impacts on berry development and in particular loss of berry mass and cell death. The aims of this research were: (i) develop a more practical and …

Effects of Air vs. Air+Soil Heating During a Simulated Heat Wave on White Oak (Quercus alba) and Black Oak (Quercus velutina)
… shifts in climate. One type of event, the summer heat wave, may already be increasing in some areas of the world. Large-scale reductions in Net Primary Productivity and mortality have been reported during heat waves in forested ecosystems. Unfortunately, our understanding of how abrupt heat-stress …

A Comparison of the Prediction Models for the Impact of Heat Wave on Total Mortality and Incidence of Heat-related Illness in the Republic of Korea
Heatwave surveillance systems of patients with heat-related illness generated by the Korea Centers for Disease Control and Prevention have been reported since 2010. So, there are few studies about relationship between incidence of heat-related illness and temperature during heat wave in Korea. This …

HOW HEATWAVES ARE CHANGING URBAN LIVABILITY ACROSS THE UNITED STATES: A CASE STUDY IN TEN COMMUNITIES
<p>Heatwaves are an important type of extreme climate event and directly result in more than 130 deaths and thousands of morbidities per year across the United States. Heat waves increase demands on water and energy, particularly in urban areas, because people use more water for drinking, …

Generation of acoustic-gravity waves in ionospheric HF heating experiments : simulating large-scale natural heat sources
… potential role played by large-scale anomalous heat sources (e.g. prolonged heat wave events) in generating acoustic-gravity waves (AGWs) that might trigger widespread plasma turbulence in the ionospheric layer. The main hypothesis is that, the thermal gradients associated with the heat wave …

Impacts of heat waves on food quantity and quality of soy bean/corn in the Midwest at ambient and elevated [CO2]
Heat waves have significant impacts on managed and unmanaged plant productivity. Yet, current studies of the effects of heat waves on crops are confined to post-mortem and historical analyses. There are no field based heat wave studies on major crops. In the past decade, the development of …

Heat Waves, Early Birth, and Vulnerable Populations: Epidemiological and Spatial Analyses in the United States
Heat waves are a serious and growing threat to human health and society. While there is no single definition of a heat wave, elevated morbidity and mortality during extreme heat is consistently observed in addition to other societal impacts, such as strain on the energy infrastructure, drought, and …

Prioritizing Preparedness: Extreme Heat and Climate Change Preparation of Midwestern Health Departments
… dissertation is about the factors that influence heat wave preparedness of Midwestern health departments, and the climate change perceptions of public health officials. Heat waves have historically impacted the Midwest and, due to the variable pattern of these events, are full of uncertainties. …

Public perception and response to extreme heat events
In the United States extreme heat events have grown in size and stature over the past 20 years. Urban Heat Islands exacerbate these extreme heat events leaving a sizable portion of people at risk for heat related fatalities. The evidence of this is seen in the Chicago heat wave of 1995 which killed …

Reconstruction of multiple climate variables at high spatiotemporal resolution based on Big Earth data platform
… terrain, five distinct metrics of long-term heat wave datasets, an updated database of water and wind erosion. For further use in practice, these datasets are freely accessible and online web application has been developed for academic research on climate change under accelerated global …

Population health and climate change: public perceptions, attitudes and adaptation to heat waves in Adelaide, Australia
… climate change will increase the frequency of heat waves which have an impact on population health. In Adelaide, unprecedented heat waves have been experienced in recent years which had significant impact on human health. The objectives of this research project were to: (1) explore public …

Investigating Climate Impacts of Urbanization and the Potential for Cool Roofs to Mitigate the Kansas City Metropolitan Area’s Urban Heat Island Effect
An urban heat island (UHI) is a phenomenon where the temperatures within cities are greater than those of surrounding rural areas due to human activity and physical properties of urban surfaces. This effect can cause the annual mean temperature within cities to be up to 3oC more than its …

Climate impact on phytoplankton blooms in shallow lakes
… of cyanobacteria during two recent summer heat wave events revealed that anomalously hot weather did not always, as often hypothesized, promote cyanobacteria in the nutrient-rich lake studied. The seasonal timing and duration of heat waves determined whether critical thresholds of thermal …

Evaluating the Time of Emergence of Heat Waves using Different Definitions
Heat extremes, such as heat waves, are characterized by human health effects, increased mortality, and ecosystem-wide impacts. Previous studies of heat waves do not define when and where heat wave frequency will be distinguishable from the background frequency of heat waves in the coming century, …

Heat exposure and adaptation strategies of outdoor informal sector workers in urban Bulawayo - Zimbabwe
… humidity levels, will exacerbate occupational heat stress, heat related illnesses and mortality amongst vulnerable groups, particularly among outdoor workers in developing countries in the tropics. In Bulawayo, Zimbabwe, a large portion of the population work outdoors in the informal sector as …

A multi-city analysis of the natural and human drivers of the urban heat island
… to the surrounding rural areas, called the urban heat island, which can have negative impacts on the health and wellbeing of urban dwellers. This study uses a novel approach of analyzing a large number of cities from around the world to investigate the similarities and differences in urban …

Outdoor wind speed enhancement in residential precincts in tropical cities
… the models over-predict the thermal effects on heated surfaces. Validated computational simulations show that void decks can increase pedestrian-level wind speeds by more than twofold in two-dimensional urban street canyons. In three-dimensional urban street canyons, void decks not only increase …

Could global warming affect space weather? : case studies of intense ionospheric plasma turbulence associated with natural heat sources
… that they were triggered by internal gravity waves that had reached the altitudes of ionospheric F region. All possible sources producing gravity waves have been examined. We rule out solar/geomagnetic conditions which were quiet, and the atmospheric weather anomalies which were absent, during …

THE VARIABILITY OF DROUGHT DYNAMICS IN THE SOUTHWEST UNITED STATES AND AN ANALYSIS OF DROUGHT RISK IN THE NORTHEASTERN UNITED STATES
… we analyzed the future risk of droughts and heat waves in the NEUS and found that GCMs, from both the last millennium ensemble (LME) and CMIP6, have a wet bias in the northeast. Radiation at the surface of the Earth is a balance between incoming solar radiation and outgoing longwave …
