A study led by NCAR postdoctoral researcher Jia Hu and Julia Klein from Colorado State University looks at the relationship between plants, water, carbon, and climate on the Tibetan Plateau, which is warming at a rate twice that of the global average.

Last year, a team of NCAR scientists verified that the Weather Research and Forecasting model (WRF) can be used to depict seasonal snowfall in Colorado with a high degree of accuracy. Now the team is using WRF to forecast future snowfall.

Strong jet streams often plow into the West Coast in wintertime, but the heaviest rains and snows occur when the flow dips far south over the Pacific, allowing it to bring an atmospheric river of warm, moist air from the subtropics to California.

Crop yields are affected by many factors, including breeding, management, and climate. New research from NCAR seeks to better understand these factors and their contributions to historical yield increases, in order to anticipate future changes.

International collaboration has always been at the heart of COSMIC, a six-satellite network that intercepts GPS signals to measure weather, climate, and space weather variables. Now one of the leading university collaborators on COSMIC, the University of Graz, is UCAR’s latest international affiliate.

Blossoming interest in geoengineering research over the last few years has ripened into a deeper consideration of the topic by scientists, policymakers, and the public. This interest has been boosted by a relative lack of action on mitigating climate change.

The wolverine is known for its strength and ferocity, but these qualities cannot protect it from a warming world. NCAR research suggests that this aggressive predator may struggle to survive in the contiguous United States over the coming century.

El Niño and La Niña are counterparts in the El Niño-Southern Oscillation (ENSO), a cyclic warming and cooling of the eastern and central Pacific Ocean that exerts a major influence on global weather patterns, but they are not mirror images.

A team of scientists led by NCAR’s Keith Oleson has incorporated urban areas into a global climate model. The development is important because most models used for predicting future climate change do not account for the urban “heat island” effect.

Just as the U.S. economy began a dramatic nosedive in 2007, so did the Arctic’s summertime sea ice. In the summer of 2010, the ice—much like the economy—continued to struggle.

In 1988, it was the spectre of Yellowstone National Park on fire. In 2003, it was the horror of thousands dying from heat in prosperous western Europe. The planet’s standout heat wave in 2010 plagued much of European Russia, including Moscow.

In Kansas City and Tulsa, overnight lows have seldom dipped much below 80°F, with consistently oppressive humidity. Pulses of tropical air flowing north and east from the Gulf of Mexico are largely to blame.

During the stormy summer of 2005, hurricanes Katrina and Rita raised concerns about the potential effects of global warming on tropical cyclones. At the same time, the Amazon rainforest was experiencing one of its most intense droughts of the last century.
