Pineapple Express, monsoonal flow, El Niño, Madden-Julian Oscillation—these are some of the atmospheric patterns that shape our weather and climate. This glossary provides definitions for the major patterns that wax and wane across our planet.

The collaborative international project, involving scientists from NCAR and other organizations, may ultimately improve tornado forecasting.

Students, gardeners, retirees, and other volunteers taking part in a nationwide initiative, Project BudBurst, are finding hints that certain plants are blooming unusually early.

Current observational tools cannot account for roughly half of the heat that is believed to have built up on Earth in recent years.
