BACKGROUND Devastating health effects from recent heat waves, and projected increases in frequency, duration, and severity of heat waves from climate change, highlight the importance of understanding health consequences of heat waves. OBJECTIVES We analyzed mortality risk for heat waves in 43 U.S. cities (1987-2005) and investigated how effects relate to heat waves' intensity, duration, or ti...

introduction temperature effects on human activities and natural processes are undeniable. temperature increase, in particular, in the form of heat waves affects all facets of life including architecture, welfare, transport, agriculture and industry. when the intensity and frequency of the waves are high, they can produce major problems. in recent years, the number and intensity of these heat w...

in this paper the propagation of harmonic plane waves in a homogeneous anisotropic magneto-piezothermoelastic diffusive body with fractional order derivative is studied. the governing equations for a homogeneous transversely isotropic body in the context of the theory of thermoelasticity with diffusion given by sherief et al. [1] are considered as a special case. it is found that three types of...

BACKGROUND Few studies have examined variation in the associations between heat waves and mortality in an international context. OBJECTIVES We aimed to systematically examine the impacts of heat waves on mortality with lag effects internationally. METHODS We collected daily data of temperature and mortality from 400 communities in 18 countries/regions and defined 12 types of heat waves by c...

Over India, heat waves occur during the summer months of April to June. A gridded daily temperature data set for the period, 1961-2013 has been analyzed to examine the variability and trends in heat waves over India. For identifying heat waves, the Excess Heat Factor (EHF) and 90(th) percentile of maximum temperatures were used. Over central and northwestern parts of the country, frequency, tot...

OBJECTIVE To assess the impact of heat waves on non-accidental deaths, and to investigate the influencing factors for deaths caused by heat waves in Jinan, China. METHODS Daily death data and meteorological data for summer days with or without heat waves in Jinan from 2012 to 2014 were collected, and a cross-over analysis was conducted to evaluate the influence of heat waves on non-accidental...

BACKGROUND There is limited evidence for the impacts of heat waves on coronary heart disease (CHD) mortality in Beijing, capital city of China. OBJECTIVES We aimed to find a best heat wave definition for CHD mortality; and explore the characteristic of heat wave effects on CHD in Beijing, China. METHODS We obtained daily data on weather and CHD mortality in Beijing for years 2000-2011. A qu...

Heat waves are a public health concern in Australia and unprecedented heat waves have been recorded in Adelaide over recent years. The aim of this study was to examine the perception and attitudes towards heat waves in the context of climate change among a group of residents in Adelaide, an Australian city with a temperate climate. A cross-sectional study was conducted in the summer of 2012 amo...

A global coupled climate model shows that there is a distinct geographic pattern to future changes in heat waves. Model results for areas of Europe and North America, associated with the severe heat waves in Chicago in 1995 and Paris in 2003, show that future heat waves in these areas will become more intense, more frequent, and longer lasting in the second half of the 21st century. Observation...

Exposures to dangerously high temperatures are a public health threat expected to increase with global climate change. Heat waves exacerbate the risks associated with heat exposure, and urban residents are particularly vulnerable to threats of heat waves due to the urban heat island effect. To understand how heat waves are changing over time, we examine changes in four heat wave characteristics...
