It takes a sharp eye to find something positive in the wreckage of the worst swarm of U.S. tornadoes on record: the 1974 Jumbo Outbreak. Millions of Americans are safer in the air because of Fujita's subsequent analysis of microbursts and tools developed by NCAR and collaborators.
Why seasonal forecasting can’t tell us with certainty what to expect this summer—and why we might soon have a stronger sense of what late 2014 and early 2015 are likely to bring to large parts of the globe.
A recent conference marked the 25th anniversary of a crucial international meeting, organized with support from UCAR, that brought together atmospheric sciences from Taiwan and mainland China for the first time in decades.
They’ve been carried by truck into supercell thunderstorms, flown on aircraft into hurricanes, and sliced and diced the atmosphere in myriad ways. Where are research radars headed next, and where will they take science and society?
Farmers and other stakeholders are hungry for guidance on how crops may fare as the nation’s climate evolves over the coming decades. This year’s National Climate Assessment includes new findings on agriculture and climate change that draw from collaborations between NCAR and the U.S. Department of Agriculture.
The nation’s newest computing facility for atmospheric and related science is poised to take the nation’s infrastructure for weather prediction, climate projection, space weather, and other key tasks to the next level.
Scientists are analyzing results from a project that pulled together chemists, radar experts, cloud physicists, forecasters, pilots, and other specialists to investigate the evolution of thunderstorms.
A nationally recognized innovator in teacher training and science education has been chosen as the new director of the Global Learning and Observations to Benefit the Environment (GLOBE) Program, which is headquartered at UCAR.
With its enormous computing capacity and speed, the new NCAR-Wyoming supercomputer will dramatically advance our understanding of Earth, helping to tackle major questions affecting our economy, health, and well-being.
States are having to make tough decisions regarding their water use and their interaction with water. NCAR scientists are involved in collaborative projects in Colorado, Louisiana, and Oklahoma to evaluate the long-term effects of today’s decisions.
One of the largest bodies of water in the United States, the Ogallala Aquifer, lies underground. Crucial to life in the U.S. Great Plains, it's one of many aquifers around the world under stress as water demands increase. Satellite data are now painting a richer picture of how these water stores are evolving.
A small, sophisticated instrument package developed at NCAR and dropped from aircraft has led to notable improvements in hurricane prediction. Now these devices are poised to deliver more data than ever, thanks to a new design and a remotely piloted NASA aircraft.
A multisatellite observing system that was only a gleam in researchers’ eyes in the 1990s is now a key tool for monitoring Earth’s atmosphere. An ambitious follow-up project could yield up to ten times the data gathered by the current satellites.
To help their students and faculty study the atmosphere in detail, campuses worldwide rely on Unidata, the UCAR-based program that keeps a 24/7 stream of weather and other environmental data flowing to classrooms.
