Atmospheric rivers deliver water vapor and can bring heavy precipitation when making landfall. A new study has found that a high-resolution climate model can demonstrate accurate details of relationships between atmospheric rivers and major Northern Hemisphere climate modes.
David Herring, Chief of the Communication, Education, and Engagement Division of the Climate Program Office, has been named a finalist for a Pinnacle Award. He has been nominated for for Climate Change Executive of the Year.
A new study from scientists at NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) and the University of Miami’s Cooperative Institute of Marine & Atmospheric Studies (CIMAS) investigates Hurricane Dorian’s track forecast uncertainties.
Drought.gov offers a new map customization feature for Tribal Nations. This feature allows users to display reservation boundaries on any map on Drought.gov.
On September 28, 2022, NOAA deployed 27-pound drone into the eye of Hurricane Ian, The drone then completed a two-hour mission, acquiring critical measurements to understand the complex storm system.
On September 21, 2022, the United States Senate successfully approved the Kigali Amendment of the Montreal Protocol. The Kigali Amendment is an international agreement to phase out and replace hydrofluorocarbons, a class of chemicals that act as potent greenhouse gasses.
El Niño-Southern Oscillation (ENSO) is centered around the eastern tropical Pacific Ocean. But a new study finds that interactions between the Pacific, Atlantic, and Indian Ocean basins affect the predictability of sea surface temperature in the tropics.
Climate change is altering wildfire behavior and vegetation in forested regions. Historically, California wildfires occurred more frequently at a lower severity, reducing surface fuels and encouraging forest growth. Modern forests have higher tree density and fuel loads, increasing fire severity.
A new study finds that citizen-science reporting of local conditions across a wet-to-dry scale reflects meteorological conditions. The data provide on-the-ground details that can be incorporated into existing drought monitoring processes.
Climate change shifts the baseline for what should be considered “normal” hydrological conditions, which shifts the definition of drought. Thirty years usually provide adequate data for climatology, but shorter periods using more recent data may work better for rapidly changing areas such as the Southwest.
