A new study highlights the dual threat of extreme humid heat and catastrophic rainfall during the Indian monsoon, while also revealing a powerful new tool to predict the monsoon up to two years in advance. The research paints a sobering picture of climate change's impact on the region.
Researchers have developed a wearable sensor that reads chemical signatures of human breath to decode silent speech into text. The device uses a microscopic nanoforest to capture rapid water vapor changes, achieving 98.51% accuracy rate.
Researchers found that atmospheric rivers have intensified in recent decades, leading to more frequent extreme rainfall events in Japan. This trend aligns with global warming and increased atmospheric water vapor content.
Researchers identified two weather patterns associated with an increased risk of headaches in the Northeast US. The study found that approaching cold fronts and high-pressure systems, such as the Bermuda High, can trigger new-onset headaches in people with episodic migraines.
In a study on Japanese macaques, researchers found that semi-shade is an important thermoregulatory option under hot, dry conditions. The macaques preferred semi-shade over full shade or sun when it was hot and dry, but not humid. This suggests that semi-shade may play a significant role in helping endotherms cope with heat stress.
Researchers at Tokyo Metropolitan University have identified a unique type of heat wave in Japan, known as 'moist heat waves,' which are accompanied by tropical cyclones and high humidity. These heat waves account for a quarter of the days surveyed and pose significant hazards due to extreme temperatures and torrential rain.
Researchers at Chalmers University of Technology have developed a compact, humidity-tolerant sensor that detects hydrogen gas in humid environments. The sensor uses platinum nanoparticles to measure the concentration of hydrogen by analyzing the thickness of a water film on its surface.
A new deep-learning model, AngleNet, significantly improves the retrieval accuracy of atmospheric relative humidity profiles from ground-based microwave radiometers. The model captures complex nonlinear relationships between brightness temperature and humidity profiles, leading to better understanding and forecasting of atmospheric the...
Researchers from the University of Maryland tracked lightning storms in real-time using NASA's TEMPO instrument, detecting nitrogen oxide emissions that affect climate and air quality. The study reveals how lightning can produce pollutants that travel long distances, influencing air quality far from the original storm.
The Amazon rainforest is a significant source of condensation nuclei for clouds, according to two studies. The rainforest's plant transpiration and thunderstorms produce aerosol particles that can be transported thousands of kilometers, influencing marine cloud formation.
A new study reveals that risks to global water security are significantly higher when considering the environmental conditions and governability of areas where moisture evaporates before falling as rain. This approach identifies regions with high water scarcity risk, including those dependent on neighboring countries for upwind moisture.
Research finds that climate change can promote Salmonella survival and internalization in romaine lettuce, making it a significant food safety issue. Climate change is predicted to increase humid periods, enhancing the ability of Salmonella to grow rapidly in lettuce.
A new study finds that human-induced climate warming has driven increasing precipitation variability over much of the globe, with hotspots in Europe, Australia, and eastern North America. The amplified variability poses significant threats to climate resilience, infrastructure development, agriculture, and ecosystems.
Climate scientists predict a 7 in 10 chance of record-breaking temperatures and humidity in the tropics, threatening humanitarian aid and medical care. El Niño's impact on tropical heat and humidity is expected to compound the effects of global warming, leading to extreme humid heat stress.
Researchers have developed a hydrogel that can absorb and retain water when combined with a hygroscopic salt, extracting almost six liters of pure water per kilo of material in 24 hours. This technology could play a fundamental role in recovering atmospheric water in drought-stricken regions.

Researchers created a humidity sensor mimicking camel noses to detect moisture levels in industrial exhaust and human skin. The device responds to changes in skin perspiration and can even follow the path of a finger, suggesting a potential basis for touchless interfaces.
The study found that plate wettability had no impact on the performance of anti-icing fluids, contradicting previous research. Smooth hydrophobic coatings were shown to prevent ice accretion and reduce water adhesion.
Researchers have developed a new method to estimate ancient atmospheric water content based on fossil plant leaf waxes, which can help predict future climate changes. By studying the chemistry of these compounds in soils and sediments, scientists can reconstruct past climates and test their understanding of global warming.
A study by ETH Zurich researchers reveals that regional variability plays a key role in extreme precipitation, with increasing atmospheric moisture and weaker vertical wind velocities contributing to differences. The decomposition of projections highlights weaknesses in existing climate models and provides insights into where to focus ...
