The annual number of tropical cyclones forming globally has decreased by approximately 13% during the 20th century, and scientists say the main cause is a rise in global warming, according to a new study in Nature Climate Change by a group of international scientists including NOAA scientists.
This summer during the 2022 Atlantic hurricane season, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) will once again be on the frontlines helping NOAA prepare the public for severe weather. They will also conduct new research on the complex processes of how tropical cyclones form, develop, and dissipate.
Accurate, high resolution weather forecasts equate to cost savings across many different industries, but it is not always clear exactly what those cost savings are.
A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin.
New climate modeling research shows heavy rainfall events will cause more frequent and stronger flash floods by the end of the century, especially in the southwest and central United States.
Salt has played an outsized role in human history. This element found in the ocean is now at the heart of new NOAA research that will potentially lead to improved forecasts of the most dangerous hurricanes.
A new NOAA-led study of precipitation high in the Colorado Rockies aims to give water managers better forecasts for runoff in the critically important Colorado River Basin.
Saildrone Inc. and NOAA have released the first video footage gathered by an uncrewed surface vehicle from inside a major hurricane barreling across the Atlantic Ocean.
NOAA and partner research on clouds and air-sea interactions will help improve a new generation of models that predict our weather and climate, according to a new summary article that is part of a special issue of the open access journal Earth System Science Data.
The National Oceanic and Atmospheric Administration today announced it has selected the University of Oklahoma to host NOAA’s Cooperative Institute for Severe and High-Impact Weather Research and Operations (CISHIWRO).
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.
