Jon Nese, host of Penn State’s “Weather World,” says you can trace the roots of a longtime partnership with the astronomy and astrophysics department to the ancient Greek meaning of the word “meteorology.”

Since 1890, the National Weather Service has relied on a network of volunteer observers.

The measures instituted in April to help curb the spread of COVID-19 across the United States may hold clues for improving air quality, according to researchers.

With the tropical storm season in the Atlantic Ocean underway, better storm track prediction has allowed timely evacuations and preparations.

"We know ice sheets are melting as global temperatures increase, but uncertainties remain about how much and how fast that will happen," said Chris Forest, professor of climate dynamics at Penn State.

A $1.4 million grant from the NSF, awarded to Chad Hanna, Edward O’Brien and Jenni Evans, will extend the reach of Penn State’s Institute for Computational and Data Sciences’ expertise across the University.

Michael E. Mann, distinguished professor of atmospheric sciences and director of the Earth System Science Center at Penn State, will share the 2020 World Sustainability Award with Antonella Santuccione Chadha.

Having a passion for meteorology, Hunter Donahue (junior-meteorology) purchased a green screen and set up a broadcast in his basement.

UNIVERSITY PARK, Pa. — Over the summer, three Penn State graduate students, Aara'L Yarber, Maria Morales-Caez and Stephanie Lin, participated in a workshop focused on the planetary boundary layer (PBL).

The Earth System Science Center has announced the lineup for its fall 2020 Climate Dynamics seminar series.

The program, led by faculty in the Department of Meteorology and Atmospheric Science and the John A. Dutton e-Education Institute, aims to help students tap into the wealth of real-time and historical weather data.

When a hurricane approaches, providing a few extra hours’ notice can be the difference between life and death.

A radar signature may help distinguish which severe storms are likely to produce dangerous tornadoes, potentially leading to more accurate warnings, according to scientists.

Although Penn State’s EnvironMentors chapter is relatively new, it has grown quickly.

Weather World's “Hurricane Week 2019” series just earned first place for best series in the Keystone Media Awards.

By the next morning, the carnage was widely known throughout the state and country.

“The possibilities for applying data science and computational science approaches are endless,” said Jenni Evans, director of ICDS and professor of meteorology and atmospheric science.

Kelly Núñez Ocasio, Meteorology and Atmospheric Science student, has received an Alfred P. Sloan Minority Graduate Scholarship.

A hailstone of more than four inches is “certainly very large,” says Matthew Kumjian, a meteorologist at Penn State University.

Rachel Gutierrez, a graduate student at Penn State and co-author of the paper, found a connection between a storm updraft’s rotational velocity, or how fast it is spinning, and larger hail size.

A good grip can mean the difference between life and death for lizards in a hurricane.

Michael Mann has been elected to the National Academy of Sciences.

After tornadoes hit his southwestern Pennsylvania hometown in 1998, 9-year-old Kyle Imhoff learned a few things. Weather events could be very dangerous — but also fascinating.

The American Meteorological Society (AMS) recently created a national award in honor of Penn State meteorology alumnus and weather pioneer Warren Washington.

Penn State researchers found that a common tool used to understand carbon dioxide fluxes, or how the gas moves between the atmosphere and ecosystems, may be overconfident because of uncertainties in the release of carbon dioxide by the combustion of fossil fuels.

A Penn State led-effort to understand greenhouse sources and sinks finds that twice as much methane is seeping into the atmosphere than the Environmental Protection Agency estimates.

Congratulations Kelly.

Snowfall trends in Washington, and other East Coast cities, are leading scientists to this conclusion: Global warming, may paradoxically be contributing to an uptick in big East Coast snowstorms.

Every minute counts when it comes to predicting severe weather.

For the first time, meteorologists have observed persistent drizzle under conditions where snow would be expected.
