Although heat waves and cold snaps pose major health risks and grab headlines when they occur, recent studies have uncovered a more complex and perhaps unexpected relationship between temperature and public health. News | Focus C limate change is expected to have profound effects on weather patterns and temperatures worldwide in the coming decades, with serious implications for public health. f...

Breaking without air entrainment of very short wind-forced waves, or microscale wave breaking, is undoubtedly widespread over the oceans and may prove to be a significant mechanism for enhancing the transfer of heat and gas across the air-sea interface. However, quantifying the effects of microscale wave breaking has been difficult because the phenomenon lacks the visible manifestation of white...

Vibrothermography is a promising technique that uses elastic ultrasonic wave excitation in solids for quality maintenance, e.g. in aerospace and automotive industry to monitor the integrity of surface or subsurface features. Vibrothermography allows for defect selective imaging using thermal waves that are generated by elastic sound or ultrasound waves. The mechanism involved is local friction ...

Generating credible climate change and extremes projections remains a high-priority challenge, especially since recent observed emissions are above the worst-case scenario. Bias and uncertainty analyses of ensemble simulations from a global earth systems model show increased warming and more intense heat waves combined with greater uncertainty and large regional variability in the 21st century....

Experiments are performed to provide an insight into the heat transfer aspects of a wavy liquid film. Local film thickness and liquid temperature are measured simultaneously using a thermal conductance thickness probe and fast response thermocouples as the wavy film falls over an electrically heated wall. Liquid temperature at a fixed distance from the wall generally increases in the thin subst...

The wind blowing over sea surface generates tiny wind waves. They develop with time and space absorbing wind energy, and become huge wind waves usually referred to ocean surface waves. The wind waves cause not only serious sea disasters but also take important roles in the local and global climate changes by affecting the fluxes of momentum, heat and gases (e.g. CO2) through the air-sea boundar...

The impact of heat stress on human health has been extensively studied. Similarly, researchers have investigated the impact of heat stress on workers' health and safety. However, very little work has been done on the impact of heat stress on occupational accidents and their severity, particularly in South Australian construction. Construction workers are at high risk of injury due to heat stres...

The adverse health effects from hot weather and heat waves represent significant public health risks in vulnerable areas worldwide. Rising temperatures due to climate change are aggravating these risks in a context of fast urbanization, population growth and societal ageing. However, environmental heat-related health effects are largely preventable through adequate preparedness and responses. P...

The most common cause of heat fatalities is environmental exposure during heat waves. Deserts of the southwestern USA are known for temperatures that exceed 32 degrees C for 30 days or more; yet, heat-related fatalities are rare among residents of the region. We compiled data from the National Weather Service and the Office of the Medical Examiner in order to determine the relationship between ...

Vibrothermogrphy is a promising technique that uses ultrasonic elastic waves to locally stimulate defects on solids specimens and is typically applied in the aerospace and automotive industries. This technique allows for defect selective imaging using thermal waves that are generated by ultrasound waves. The mechanism involved is frictional heating or hysteresis that turns a dynamically loaded ...
