Penn State scientists join Pacific field campaign to study extreme rainfall

— posted on Sep 01, 2022 04:51 PM

The researchers are participating in the Prediction of Rainfall Extremes Campaign in the Pacific (PRECIP), a $6 million field campaign in Taiwan and Japan funded by the National Science Foundation to improve our understanding of the processes that produce extreme precipitation.

Carbon flow through inland and coastal waterways, implications for climate

— posted on Apr 07, 2022 11:11 AM

A recent study by an international team of scientists including Raymond Najjar, professor of oceanography at Penn State, found that the flows of carbon through the complex network of water bodies that connect land and ocean has often been overlooked and that ignoring these flows overestimates the carbon storage in terrestrial ecosystems and underestimates sedimentary and oceanic carbon storage.

Microwave data assimilation improves forecasts of hurricane intensity, rainfall

UNIVERSITY PARK, Pa. — In 2017, Hurricane Harvey stalled after making landfall over coastal Texas, pouring down record rainfall, flooding communities and becoming one of the wettest and most destructive storms in United States history. A new technique using readily available data reduces forecast errors and could improve track, intensity and rainfall forecasts for future storms like Hurricane Harvey, according to Penn State scientists.

“Our study indicates that avenues exist for producing more accurate forecasts for tropical cyclones using available yet underutilized data,” said Yunji Zhang, assistant research professor in the Department of Meteorology and Atmospheric Science at Penn State. “This could lead to better warnings and preparedness for tropical cyclone-associated hazards in the future.”
