How does data assimilation affect subseasonal Tropical Pacific forecasts?

October 24, 2023

A new study finds that data assimilation in Tropical Pacific models can improve predictions of sea surface temperature, but may not benefit predictions of mixed layer depth.

NOAA scientists link exotic metal particles in the upper atmosphere to rockets, satellites

October 17, 2023

Besides meteoric “space dust,” the atmosphere more than seven miles above Earth’s surface is peppered with particles containing metals from satellites and spent rocket boosters vaporized by the intense heat of reentry.

NOAA explores how uncrewed aircraft can improve aerosol and cloud measurements

October 14, 2023

NOAA teamed up with industry aircraft professionals to test the use of uncrewed aircraft to gather observations. Science payloads can help NOAA address air quality, the role of aerosols in Earth’s energy budget, and atmospheric interactions.

Why hasn't the central US warming hole disappeared?

October 14, 2023

Amid rising temperatures in the Western and Eastern United States, a cooling trend has dominated summer daytime temperatures over the central United States since the mid-twentieth century. A new study examines the role of natural variability.

Finding missing sources of abundant atmospheric pollutants formic and acetic acid

October 14, 2023

Formic and acetic acid, which contribute to acid rain and aerosols, are too abundant for scientists to identify all their sources. A new study explains why models tend to underestimate their extent.

New models and ocean management tool shows marine heatwave eEffects on predator habitats

October 6, 2023

Sharks, seals, birds, and fish count among predator species in the Northeastern Pacific that are ecologically, culturally, and commercially valuable. A new study shows how marine heatwaves affect predators differently.

Scientists find new driver for tropical Atlantic climate

October 6, 2023

Sea surface temperatures, storms, greenhouse gases, aerosols, and natural radiation all affect the tropical Atlantic climate. A new study finds that a north-to-south ocean temperature gradient is a key driver of Atlantic hurricanes and Sahel rainfall.

Arctic airborne investigations and research project takes flight

October 3, 2023

NOAA and partner scientists recently completed two successful field tests in the US Arctic merging new technologies and traditional ship surveys of phytoplankton species distributions in response to surface warming.

Five unexpected consequences of extreme heat

September 26, 2023

Extreme heat has implications for power grid infrastructure, food production and nutrition, childhood education, worker health and safety, and crime.

Flash droughts in the Caribbean

September 26, 2023

Islands in the Caribbean can enjoy near-daily rainfall but have limited freshwater reserves, making them especially vulnerable to sudden, rapid drying. A new study identifies instances of widespread flash drought outbreaks.
