Urban landscapes and human-made aerosols have the potential to not only make gusts stronger and hail larger; they can also start storms sooner and even pull them toward cities, according to new research exploring the impact of urban development on hazardous weather, led by PNNL researchers.
A model based solely on the past 40 years of weather events uses 7,000 times less computer power than today’s weather forecasting tools. An A.I.-powered model could someday provide more accurate forecasts for rain, snow and other weather events.
While offshore wind projects provide clean and renewable energy, a new study from the University of Delaware shows that they can also have unintended effects on local weather in the form of minimal, though statistically significant, impacts when it comes to wind speed and reduced precipitation at nearby onshore locations.
During tornado formation, sound waves are produced at very low frequencies. And if your name is GLINDA, you do not need to be in Oz to hear them. Brandon White, at Oklahoma State University, is part of an engineering team that developed the Ground-based Local Infrasound Data Acquisition (GLINDA) system for the acoustic measurement of weather phenomena. He will discuss its design and capabilities at the 179th Meeting of the Acoustical Society of America, Dec. 7-10.
Researchers from the Niels Bohr Institute, University of Copenhagen have, in collaboration with Norwegian researchers in the ERC Synergy project, ICE2ICE, shown that abrupt climate change occurred as a result of widespread decrease of sea ice.

In April 2020, as remote work and social distancing policies were in place in Delaware and a number of other states, there was a sense the skies were clearer and less polluted with fewer people on the road. But new research from a team led by University of Delaware, Penn State and Columbia University researchers found a murkier picture.
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?
Warren Knapp, professor emeritus of meteorology and climate in the Department of Earth and Atmospheric Sciences at Cornell University, and the second director of Cornell’s Northeast Regional Climate Center, died Oct. 3 in Ithaca. He was 82.
Climate science has focused on avoiding false alarms when linking extreme weather to climate change. But when meteorologists warn of hazardous weather, they include a second key measure of success -- the probability of detection.
Nearly 30 years after recording a temperature of minus 93.2 degrees Fahrenheit (minus 69.6 Celsius) in Greenland, the measurement has been verified by the World Meteorological Organization as the coldest recorded temperature in the Northern Hemisphere. The measurement was first recorded by a University of Wisconsin–Madison Antarctic Meteorological Research Center Automatic Weather Station in December 1991.
Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system.
Upcoming 5G wireless networks that will provide faster cell phone service may lead to inaccurate weather forecasts, according to a Rutgers study on a controversial issue that has created anxiety among meteorologists.
How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It’s a deceptively complicated question, so a Rutgers-led group of scientists recommends combining two cutting-edge tools to help answer the crucial climate change-related question.
Droughts impact millions of people and threaten the delicate ecosystems of the Amazon rainforest in South America.
Turbulent air in the atmosphere affects how cloud droplets form. New research from Michigan Technological University’s cloud chamber changes the way clouds, and therefore climate, are modeled.
A new cluster of weather-monitoring stations will offer New York City’s energy provider real-time data to keep service reliable and resilient for its customers.
Bill Gallus, an Iowa State storm expert (and chaser), was as surprised as anybody by the Aug. 10 derecho that blew across Iowa and the Midwest. He expects researchers will take a good look at why the violent, straight-line winds didn't show up in forecasts.
The University of Oklahoma is leading a National Science Foundation AI Institute for Research on Trustworthy AI in Weather, Climate, and Coastal Oceanography that is being hailed as a “historic milestone in environmental science.”
Temperatures in the Arctic Ocean between Canada, Russia and Europe are warming faster than researchers' climate models have been able to predict.
NSF recently announced an investment of more than $100 million to establish five AI Institutes to support research and education hubs nationwide. Amy McGovern, an OU professor with dual appointments in the School of Computer Science in the Gallogly College of Engineering and in the School of Meteorology in the College of Atmospheric and Geographic Sciences, will lead the NSF AI Institute for Research on Trustworthy AI in Weather, Climate, and Coastal Oceanography, which received $20 million of the NSF funding.
New analysis of almost 30 years' worth of scientific data on the melting of the Greenland Ice Sheet predicts global sea level rise of at least 10 centimetres by the end of the 21st Century if global warming trends continue.

When a hurricane approaches, providing a few extra hours’ notice can be the difference between life and death. Now, Penn State researchers report that applying a machine learning technique to a group of possible storm paths could help meteorologists provide more accurate medium-term forecasts and issue timely warnings to communities in the path of these potentially deadly storms.
Irvine, Calif., Aug. 3, 2020 — Environmental engineers at the University of California, Irvine have developed a new framework for characterizing snow droughts around the world. Using this tool to analyze conditions from 1980 to 2018, the researchers found a 28-percent increase in the length of intensified snow-water deficits in the Western United States during the second half of the study period.
NASA's Terra satellite obtained visible imagery of Potential Tropical Cyclone 9 after it moved into the Eastern Caribbean Sea and continued bringing heavy rainfall and gusty winds to the Leeward Islands, the U.S. and British Virgin Islands and Puerto Rico.
The U.S. Department of Energy (DOE) announced $19 million in funding for 31 new projects in atmospheric sciences aimed at improving the power of Earth system models to predict weather and climate.
Hurricane Lane was an impactful event for the Hawaiian Islands.
Weather forecasts have become less accurate during the COVID-19 pandemic due to the reduction in commercial flights, according to new research.
New data analytics process evaluates how global energy consumption, as well as urban green infrastructure, can affect climate change.
Utility-scale photovoltaics are the largest sector of the overall solar market within the U.S. and the fastest-growing form of renewable power generation, and this fleet of utility-scale photovoltaic projects is relatively young and hasn’t been operating long enough to establish a lengthy history of operational field service. In the Journal of Renewable and Sustainable Energy, researchers assess the performance of 411 utility-scale photovoltaic projects built within the U.S. from 2007 through 2016.
Studies have shown the Arctic is warming roughly twice as fast as the rest of the world, and its soil holds twice the amount of carbon dioxide as the atmosphere. New research from San Diego State University finds that water from spring snowmelt infiltrates the soil and triggers fresh carbon dioxide production at higher rates than previously assumed.
