A range of observing and modeling tools is helping researchers at NCAR and elsewhere discern previously unmapped links between weather events in various layers of the atmosphere, with implications for aviation, GPS, and other technology society relies on.
There's major disagreement among scientists on exactly what might be causing a tendency toward colder winters over the last few years in places like the central and eastern United States, Europe, and Russia.
Almost a year after Colorado’s deadly and destructive floods of September 2013, a group of NCAR scientists has just completed testing an innovative new system for detecting and predicting torrential rainfall as well as the risk of local flooding.
Known from their frequent film and TV appearances, the large, charismatic birds are in danger. By 2100, according to a new study, their numbers will have fallen by around 19% and will continue to decline, qualifying the species for endangered status.
How does the U.S. winter of 2013–14 rank against its predecessors? And was it a harbinger of more cold winters to come for parts of the country, or simply an outlier at a time of largely warming winters?
In parts of California and Oregon, 2013 was the driest calendar year on record, with no sign of relief on the horizon. NCAR scientists are examining how water and energy use intersect across this drought-prone region and how the nexus could evolve in a future climate.
The globally averaged surface air temperature hasn’t risen much in the last 15 years, but new research confirms ample heating of Earth, which becomes evident when looking at certain times of year and in particular locations, including deep in the ocean.
If the official weather forecast holds, Sunday's Super Bowl won’t have to be postponed. But the outlook would be far more uncertain if predictions today were as primitive as they were at the time of the first Super Bowl in 1967.
Next month’s Super Bowl will be the first ever held in an open stadium in the northern U.S. What weather might we expect two weeks from now, and how might research improve a forecast in that time range?
Just as forecasters now peg the odds of a busy Atlantic hurricane season months in advance, we might soon have outlooks that assess the risk of an active tornado season weeks or even months ahead of time.
The world of severe storm science was shaken by the deaths of three longtime researchers in a vicious tornado on May 31. The storm also raised serious questions about how urban dwellers can best respond to tornado threats.
Carbon dioxide concentrations in the atmosphere have crossed a major threshold: 400 parts per million. Here are five key points on how carbon dioxide is affecting Earth’s atmosphere and the role we're playing in it.
The last month has seen a trail of smashed records across the central United States, as pulse after pulse of cold air careened down the Great Plains. How does this fit into the bigger picture of a warming U.S. climate?
Forests across western North America have been ravaged by the most extensive bark beetle attacks on record. Scientists are getting a better handle on what comes next—and the answers aren’t as straightforward as they expected.
A major winter storm is threatening the Washington, D.C., area this week, on the heels of record-setting snowfalls and blizzard conditions in several parts of the United States last month. Are these onslaughts catching people off guard?
Satellite images have revealed at least three dramatic eye-like features not far off the U.S. Atlantic and Pacific coasts over the last several weeks. While these can look startlingly like the eyes of hurricanes, they’re not quite the same thing.
