While there has been much attention focused on the question of whether climate change influences hurricanes, scientists are also interested in whether the reverse holds true: do hurricanes significantly impact global climate?
On November 8, 2007, scientists Giuliana de Toma and Roberto Casini noted something very unusual in observations of a solar prominence collected at NCAR's Mauna Loa Solar Observatory (MLSO). Prominences are magnetic structures that appear as clouds of cool, very dense material suspended for days or weeks in the much hotter, less dense solar corona.
NCAR postdoctoral researcher Yongku Kim is using epidemiologic data to study the effects of ozone regulation on human health. He’s leading an assessment of how various regulatory standards for ozone may affect non-accidental mortality, including respiratory-related deaths during ozone season.
Accurate, high-resolution weather forecasts are a critical part of wind energy production. In December, UCAR signed an agreement with Xcel Energy to develop a wind prediction system for the company’s wind energy farms in Colorado, Minnesota, and Texas.
Several red-eye commercial flights were rocked by moderate to severe turbulence as they flew across northeast Kansas early on June 17, 2005. A new study by NCAR scientists Stan Trier and Bob Sharman uses modeling to connect storms in Oklahoma with the Kansas turbulence.
Lake Victoria's water levels reached a 40-year low in 2006 when East Africa was gripped by drought. A study by NCAR scientist Sean Swenson shows that drought was not the only cause of Lake Victoria's shrinkage—human management at the dam was also to blame.
NCAR scientists Bill Large and Steve Yeager have produced a new analysis of the exchanges of heat, momentum, and moisture between the oceans and atmosphere that should help climate modelers better assess variability on several time scales.
NCAR scientist Brian O’Neill is building an integrated assessment model to link a range of societal factors, such as future global economic and population trends, with the physical science of climate change.
In a potential boon for agriculture, a NASA-funded effort that involves NCAR and the private firm DTN/Meteorlogix has produced one of the world’s most accurate systems for predicting soil temperature up to two days in advance.
Research from MIRAGE (Megacities Impacts on Regional and Global Environments), a field campaign held in Mexico City in 2006, is coming to fruition as scientists begin to publish their findings. A new paper details the ozone “weekend effect” in Mexico City and its implications for local air pollution.
