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.

Increased storminess may give rise to North Atlantic’s ‘cold blob.’

While climate change is making much of the world warmer, temperatures in a subpolar region of the North Atlantic are getting cooler. A team of researchers report that changes in the wind pattern, among other factors, may be contributing to this “cold blob.”

The Chesapeake Bay is a ‘sink’ for plastic pollution

The vast majority of plastic pollution that makes its way into the rivers of the Chesapeake Bay stays in and along local waters and is not, as researchers put it, “exported” to the ocean.

Yunji Zhang, Eugene Clothiaux, Steven Greybush, Xingchao Chen and others lead research initiated by the late Fuqing Zhang for more accurate storm rainfall and intensity forecasts.

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.”
