Giant Australian bushfire injected 1 million tons of smoke in the atmosphere

Giant Australian bushfire injected 1 million tons of smoke in the atmosphere

Massive high-altitude clouds of smoke warmed the Southern Hemisphere's stratospshere by about 1 degree Celsius for six months, and likely contributed to the large and persistent ozone hole that formed over Antarctica during the austral spring.

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020

The global average carbon dioxide level in the atmosphere surged at the fifth-highest rate in NOAA's 63-year record during 2020. Preliminary estimates of the increase in methane levels indicate it may have been the largest annual jump on record.

Short-range weather modeling application released to forecasting community

Short-range weather modeling application released to forecasting community

NOAA and partners have released the source code for its next-generation short-range forecast application to the weather research community to accelerate development of the model, which predicts atmospheric behavior on a timescale from less than an hour to several days, including critical life-saving weather and water forecasts during extreme events.

New rating system charts a path to improved tornado forecasts

New rating system charts a path to improved tornado forecasts

All tornadoes -- whether large or small -- originate from thunderstorms, but not all thunderstorms are the same.  Nighttime twisters, summer tornadoes and smaller events can be tougher to forecast.  New research in the Bulletin of the American Meteorological Society presents a method for rating the skill of tornado warnings based on environmental challenges.

Emissions of a banned ozone-depleting gas are back on the decline

Emissions of a banned ozone-depleting gas are back on the decline

New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.

Cooling effect of clouds generated by shipping overestimated, study says

Cooling effect of clouds generated by shipping overestimated, study says

New research indicates that man-made clouds formed along shipping routes dissipate too quickly to provide insight into the cooling effect of naturally occuring marine clouds.

Frigid Arctic air outbreaks may be predictable, new research suggests

Frigid Arctic air outbreaks may be predictable, new research suggests

Known for precipitating outbreaks of Arctic air, stratospheric events in polar regions often cause other kinds of extreme weather. Since the stratosphere takes a long time to recover after these events, scientists may be able to improve predictability of extreme weather weeks ahead of time.
