Four factors, the El Niño-Southern Oscillation, North Atlantic subtropical high, low-level jet, and water vapor transport from Gulf of Mexico, primarily influence hail occurrence in the Northern Great Plains

Leung was honored for pioneering approaches in climate modeling, discovering unexpected impacts of regional climate change, and understanding extreme weather events and their future changes.

A new model offers more accurate predictions of how intensely hurricanes may strike.

New estimates show that coastlines around the world will experience an increase in the frequency of extreme sea level events at a range of global warming levels.

Researchers measured the complex air flow that governs the formation of clouds and thunderstorms over Argentinian mountains.

Scientists created a benchmark dataset and explored new algorithms to better predict changes in the intensity of North Atlantic tropical cyclones.

Researchers quantified the contributions of four different types of convective storms to summer extreme precipitation in the Mid-Atlantic region.

Rotational Hammer Riveting, developed by PNNL, joins dissimilar materials quickly without preheating rivets. The friction-based riveting enables use of lightweight magnesium rivets and also works on aluminum and speeds manufacturing.

Extreme sea levels will become 100 times more frequent by the end of the century around the world, according to a new study.

Atmospheric Scientist Beat Schmid helped develop a report assessing the scientific need for a new large aircraft at NASA.

PNNL bioenergy expert Dan Gaspar was awarded the R.A. Glenn Award for Best Paper at the American Chemical Society Fall Meeting on August 24.

An analysis of Panamanian forests found two different sets of correlating hydraulics traits in tropical trees.

Laboratory fellow title given to those who have reached the top of their field and earned international recognition from peers.

A discovery from PNNL and Washington State University could help reduce the amount of expensive material needed to treat vehicle exhaust by making the most of every precious atom.

Differences in background moisture transport explain how climate variability modes influence the frequency of landfalling atmospheric rivers and their corresponding precipitation.

Sherman Beus, software engineer, Katie Dorsey, communications team writer and editor, and Brian Ermold, data ingest manager, receive 2021 Atmospheric Radiation Measurement User Facility Service Awards.

Examining flood occurrences associated with mesoscale convective systems and their characteristics allows researchers to explore climate-flood linkages.

Large ensemble simulations show that aerosols can significantly modify the predictability of hail and precipitation in hailstorms.

A new report led by PNNL identifies the top 13 most promising waste- and biomass-derived diesel blendstocks for reducing greenhouse gas emissions, other pollutants, and overall system costs.

Researchers developed two solutions for air-conditioning—a novel, energy-efficient dehumidification system and a technology to detect refrigerant leaks. Both help increase energy-efficiency and reduce costs.
