D.C. Storms Kick Off Lightning Safety Awareness Week

The Washington D.C. Lightning Mapping Array (DCLMA) consists of 10 sensors that monitor very high frequency radio waves emitted by lightning. The DCLMA has been operational since 2007, providing detailed 3-D lightning observations that help inform decision makers regarding severe weather and lightning threats. The DCLMA clearly depicts the areal coverage of lightning in real time, and recent studies indicate that increasing lightning flash rates often precede severe winds, hail, and tornados.

Sea level rise concerns also begin to rise, especially in Norfolk

Not only is it definite that sea levels are rising, but it is also clear that the level of the Chesapeake Bay is rising twice as fast as global rates, according to ESSIC professor Raghu Murtugudde. The Associated Press published a story Monday that said U.S. Geological Survey scientists have found that the entire East Coast is particularly in danger of rising sea levels. Murtugudde, director of the Chesapeake Bay Forecast System Project, said that part of the problem is that with every …

Busalacchi hopes May Climate Impacts Symposium will prompt future discussion

The Metropolitan Washington Council of Governments (COG) hosted the Climate Impacts Symposium on May 21 regarding the planning implications of potential changes in precipitation patterns, sea level rise, flooding and water quality in the Washington metropolitan area. The meeting sought to address questions about what can be learned from existing data, how can climate trends influence water, land use and transportation planning, what can be done about predicted outcomes and what are the next …

Climate Change Weekly Roundup: 06/25/12

Publication – NewsWise
Date: June 17, 2012 “Arctic Methane Seeps Could Spell Trouble for Florida” A four-member team of researchers found as the ancient reserves of methane gas seep from the melting Arctic ice cap, the permafrost thaws and there is a release of methane – a powerful greenhouse gas that causes climate warming. Their findings, published in Nature Geoscience, documented a large number of gas seep sites in the Arctic where permafrost is thawing and glaciers receding (they found …

Nature Releases New El Niño Study by UMD ESSIC Scientist

Sunday, 24 June 2012

Researcher Raghu Murtugudde, of the University of Maryland’s Earth System Science Interdisciplinary Center, and Nandini Ramesh, co-authored a new study billed as a breakthrough in the predictability of the El Niño effect, a process involving uncharacteristically warm ocean temperatures in the tropical Pacific.

The study, which Nature published today, finds that the Bjerknes feedback, a process that alters the volume of cold deepwater that rises in the East Pacific, is not an essential

Yu leads study on aerosol import to North America

A study conducted by ESSIC Associate Research Scientist Dr. Hongbin Yu and a team of scientist that assesses the contributions of cross-ocean aerosol transport to North America was published in Science Magazine (3 AUGUST 2012, VOL. 337, #6094). In the study, titled “Aerosols from Overseas Rival Domestic Emissions over North America”, the team estimates, from NASA satellite observations, that the mass of aerosols arriving at North American shores from overseas is comparable to the total mass …

ESSIC researcher launches website for satellite measurement project

Uncertainty can be a dangerous force of doubt when dealing with research data. Dr. Yudong Tian, an associate research scientist at ESSIC, is nearing the end of the first phase of a project to address this issue by developing a way to accurately predict uncertainties in satellite precipitation measurements. The first year of the three-year project has focused on collecting “huge amounts” of satellite data. The next two years will focus on analyzing this data and creating models that can be …

Urban watershed study proposes new concepts of urban ecosystems

A study co-authored by Dr. Sujay Kaushal, assistant professor at ESSIC and the Department of Geology at the University of Maryland, and hydrologist Ken Belt proposes an expanded view on urban watersheds. The study, entitled “The urban watershed continuum: evolving spatial and temporal dimensions,” mainly considers a new part of urban ecosystems, infrastructure. With watersheds expanding and cities and urban environments changing over time, the study presents a new concept for the effects …

NOAA predicts near-normal hurricane season

Conditions in both the atmosphere and the ocean favor a near-normal hurricane season in the Atlantic Basin this season, according to NOAA. Beginning June 1, NOAA’s Climate Prediction Center says there is a 70 percent chance of nine to 15 named storms – with winds topping 39 mph or higher – for the entire six-month hurricane season. Of the storms, four to eight will strengthen to a hurricane – with winds topping 74 mph or higher – and of those, one to three will become major …
