Researchers model urban airflows to help improve the design of drones, skyscrapers, and natural ventilation systems.
Researchers are studying a tornado's song and other 'doors to danger' in an increasingly chaotic world.
Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research.
The Sentinel-6 Michael Freilich satellite will extend a nearly 30-year continuous dataset on sea level collected by an ongoing collaboration of U.S. and European satellites while enhancing weather forecasts and providing detailed information on large-scale ocean currents to support ship navigation near coastlines.
Following a year of on-site analyses at a Phoenix-area park, hydrologists identified that the park showed what meteorologists call the 'oasis effect,' a microclimate that is cooler than a surrounding dry area due to the evaporation of a water source.
Across the Wasatch Front, both researchers and community members maintain enough air quality sensors to provide a high-resolution picture of how the smoke moved through the valley -- perfect for testing and refining smoke forecast models.
A new kind of radar could make it possible for self-driving cars to navigate safely in bad weather. Electrical engineers developed a clever way to improve the imaging capability of existing radar sensors so that they accurately predict the shape and size of objects in the scene. The system worked well when tested at night and in foggy conditions.
New research reveals that tropical cyclones were actually more frequent in the southern Marshall Islands during the Little Ice Age, when temperatures in the Northern Hemisphere were cooler than they are today. This means that changes in atmospheric circulation, driven by differential ocean warming, heavily influence the location and intensity of tropical cyclones.
3D printing and low-cost sensors have made it possible to build a weather station for a few hundred dollars. Could these inexpensive, homegrown versions perform as well as their pricier counterparts?
A group of climate experts make the case for including paleoclimate data in the development of climate models. Such models are used globally to assess the impacts of human-caused greenhouse gas emissions, predict scenarios for future climate and propose strategies for mitigation.
Effective national and local governments are associated with fewer deaths from tropical cyclone disasters -- even in countries with similar levels of wealth and development.
New research is adding some clarity on weather's role in COVID-19 infection, with a new study finding that temperature and humidity do not play a significant role in coronavirus spread.
The biggest study yet of West Coast wildfire plumes shows how a smoke plume's chemistry changes over time. Results suggest current models may not accurately predict the air quality downwind of a wildfire.
Hurricanes, the United States' deadliest and most destructive weather disasters, are notoriously difficult to predict. With the average storm intensity as well as the proportion of storms that reach category 4 or 5 likely to increase, more accurate predictions of future hurricane impacts could help emergency officials and coastal populations better prepare for such storms -- and ultimately, save lives.
With the tropical storm season in the Atlantic Ocean underway and already well into the Greek alphabet for naming, better storm track prediction has allowed timely evacuations and preparations. However, the formation and intensification of these storms remains challenging to predict, according to an international team of researchers who are studying the origin of tropical cyclones.
Microplastics (plastics <5mm) and their negative health impacts have been studied in oceans, rivers, and even soils, and scientists are beginning to grapple with the myriad human health impacts their presence might have. One understudied, but critical, link in the cycle is groundwater, which is often a source of drinking water.
New management approaches and technology have allowed the US. Corn Belt to increase yields despite some changes in climate. However, soil sensitivity to drought has increased significantly, according to a new study that could help identify ways to reverse the trend.
Climate science has focused on avoiding false alarms when linking extreme events to climate change. But it could learn from how weather forecasters warn the public of hazardous events to include a second key metric: the probability of detection.
Radar satellites can collect massive amounts of remote sensing data that can detect ground movements -- surface deformations -- at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements. Now, researchers have used artificial intelligence (AI) to clear up that noise, drastically facilitating and improving near real-time observation of volcanic movements and the detection of volcanic activity and unrest.
New research shows that while winter rains can temper the beginning of the wildfire season, monsoon rains are what shut them down. This monsoon season was the second-driest on record, leaving Southern Arizona dry and vulnerable.
