NOAA researchers set out this week on a two-week mission to fly over the Arctic to measure how much the ice has melted over the summer and gauge the speed of this fall’s refreezing of sea ice. This is the second year in a row scientists have flown above Arctic waters. Data gathered from both years is testing a hypothesis that increased summer heat stored in the newly sea-ice free areas of the Arctic Ocean lead to surface heat fluxes in autumn that are large enough to have impacts on atmospheric temperature, humidity, wind and cloud distributions.
Last September’s widespread flooding in northeast Colorado, which saw just over 17 inches of rain in one week in the city of Boulder, was not made more likely or more intense by the effects of human-induced climate change, according to a new NOAA-led study published today in the Bulletin of the American Meteorological Society.
Deborah H. Lee, the chief of water management for the U.S. Army Corps of Engineers’ Great Lakes and Ohio River Division, has been named the new director of NOAA’s Great Lakes Environmental Research Laboratory (GLERL). Lee is slated to begin on December 1, 2014.
For the last five years, NOAA has teamed up with NASA to fly NASA’s Global Hawk unmanned aircraft to get an inside look at how hurricanes form and intensify over the Atlantic. The NASA-led project called the Hurricane and Severe Storm Sentinel mission is demonstrating the ability of the Global Hawk to fly over hurricanes to gather continuous weather data on flights that are longer in duration than possible with manned aircraft. In the next three years, NOAA will take the next step with the Global Hawk, leading a new experiment and continuing its important collaboration with NASA. Drawing on technology and expertise honed in the current mission, NOAA will assess the feasibility of regular operations of Global Hawk to improve day-to-day forecasts of severe storms forming over the Atlantic, Pacific and Arctic oceans.
This summer, NOAA scientists and partners are launching a number of new unmanned aircraft and water vehicles to collect weather information as part of a coordinated effort to improve hurricane forecasts.
Several of these research projects and other NOAA led efforts to improve hurricane forecasting were made possible, in part, because of the Disaster Relief Appropriations Act of 2013. The act was passed by Congress and signed by the President in the wake of Hurricane Sandy. It provides $60 billion in funding to multiple agencies for disaster relief. NOAA received $309.7 million to provide technical assistance to those states with coastal and fishery impacts from Sandy, and to improve weather forecasting and weather research and predictive capability to help future preparation, response and recovery from similar events.
Rising temperatures will tend to reduce the amount of water in many of Colorado’s streams and rivers, melt mountain snowpack earlier in the spring, and increase the water needed by thirsty crops and cities, according to the new report, “Climate Change in Colorado: A Synthesis to Support Water Resources Management and Adaptation,” which updates and expands upon an initial report released in 2008.
The growth of wind-generated power in the United States is creating greater demand for improved wind forecasts. To address this need, the Department of Energy is working with NOAA and industry on the Wind Forecast Improvement Project, funded and led by DOE.
More than 200 national and international lightning experts are gathering this week in Norman, Oklahoma, for what organizers have called “the most important international conference on atmospheric electricity in the world.” Held every four years, the 2014 International Conference on Atmospheric Electricity is co-hosted by NOAA’s National Severe Storms Laboratory and the University of Oklahoma’s College of Atmospheric and Geographic Sciences, and features the latest research on lightning and other electrical phenomena in the atmosphere.
Over the past 30 years, the location where tropical cyclones reach maximum intensity has been shifting toward the poles in both the northern and southern hemispheres at a rate of about 35 miles, or one-half a degree of latitude, per decade according to a new study, The Poleward Migration of the Location of Tropical Cyclone Maximum Intensity, published tomorrow in Nature.
