A new study from NCAR uses an innovative computer model to investigate events called sudden stratospheric warmings (SSWs) in the Arctic atmosphere. The study focuses on how two atmospheric patterns based in the tropics, the El Niño–Southern Oscillation and Quasi-Biennial Oscillation, affect SSWs.

A new NCAR study compares two different methods for forecasting power production at wind farms: turbine-based versus farm-based.

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.
