The hot and dry Santa Ana winds are associated with many of Southern California’s destructive wildfires, and even take the blame for tense, ugly moods. Now, NOAA researchers have found that on occasion the winds have an accomplice in contributing to California’s wildfires: atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface.
The Southern Ocean that encircles Antarctica lends a considerable hand in keeping Earth's temperature hospitable by soaking up half of the human-made carbon in the atmosphere and a majority of the planet's excess heat. Yet, the inner workings — and global importance — of this ocean that accounts for 30 percent of the world's ocean area remains relatively unknown to scientists, as observations remain hindered by dangerous seas.
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.
NOAA scientists have developed a new high-resolution climate model that shows southwestern Australia’s long-term decline in fall and winter rainfall is caused by increases in manmade greenhouse gas emissions and ozone depletion, according to research published today in Nature Geoscience.
A 2011 NOAA research paper that tied weaker South Asian summer monsoons to human activities has won the World Meteorological Organization’s Norbert Gerbier-MUMM International Award for 2013.
NOAA researchers will be using several innovative tools, techniques, and research results during the 2012 hurricane season to continue to improve hurricane forecasting. Read our 2012 hurricane research news briefs to learn more.
Springtime air pollution from Asia, swept across the Pacific Ocean on winds, can contribute to episodes of high surface ozone pollution in the western United States.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
