A new study by NCAR scientists looks at the accuracy of snow gauges. Making accurate measurements of snowfall is critical for weather forecasting, climate studies, and hydrology. But a combination of snow gauge geometry and weather conditions can lead to systematic measurement errors.

New research indicates reduced spring snowpack and warmer summer temperatures will affect wolverine habitat.

These maps show a few of the most heavily researched atmospheric patterns that appear as regional modes or oscillations. Many other similar patterns are defined at our glossary, where you’ll also find more detail on each of the patterns shown here.

Geoengineering our climate system to ward off the effects of global warming may end up cooling the tropics to below present-day levels.

In December 2010, media dutifully reported the heavy snow that battered the northeast U.S. and the United Kingdom’s coldest December in at least 100 years. Meanwhile, the sparsely populated Canadian Arctic basked in near-unprecedented mildness.
