Delaware Environmental Observing System detects rare tornado in state

A University of Delaware monitoring network picked up a tornado that touched down in Newark on June 10, according to a release. Tornadoes are rare in the state, but sensors were there to capture it. The Delaware Environmental Observing System, which supplies data to the National Weather Service, charted the tornado with winds of 65 to 85 mph. The observing system also measured the heavy rain that accompanied the tornado. Experts say a low-pressure system and cold front in the Ohio Valley met with warm air in Delaware, which set off the churning clouds that ultimately generated the tornado. The tornado was picked up by a weather station nearly a half mile away, which measured wind speeds at 20 mph.

USGS weather station network monitors Arctic Alaska's climate

When the U.S. Geological Survey began building their climate and permafrost monitoring network in Arctic Alaska in 1998, there wasn't much precedent for how to build the infrastructure for the instruments in the region's unforgiving environment. That meant the scientists had to learn the particulars on the fly. For example: On the great expanse of flat, barren tundra, a weather station sticks out like a sore thumb to a curious grizzly bear. "The initial stations were pretty fragile," said Frank Urban, a geologist with the USGS Geosciences and Environmental Change Science Center. "So the bear and those stations--the bear won every single time without any problem.

Cooling water from Northeast U.S. power plants keeps rivers warmer

Rivers are a vital cooling source for power plants, but high-temperature water returned to rivers from the plants may detrimentally heat rivers and change aquatic ecosystems, according to a recent study. Scientists from the University of New Hampshire and the City College of New York gathered federal data on power plants and river systems and linked up river flow and heat transfer models to figure out just how hot rivers get in the northeastern U.S. They found that about one third of heat generated in thermoelectric power plants in the Northeast is drained into rivers via used cooling water. Just more than a third of the total heat generated at plants in the Northeast is converted directly into electricity for consumer use.
