Our Mission

CAPS's mission is to develop and demonstrate techniques for the numerical analysis and prediction of high-impact local weather and environmental conditions, with emphasis on the assimilation of observations from Doppler radars and other advanced in-situ and remote sensing systems.

CAPS conducts a broad-based program of basic and applied storm-scale research, and its award-winning Advanced Regional Prediction System (ARPS) is used worldwide.

CAPS strives to be the world leader in convective-scale data assimilation and numerical weather prediction, providing a venue for exploring bold new ideas, attracting the best scientists and students, and facilitating the transfer of knowledge and technology to academia, government and industry.

  • February 8, 2024: Dr. Daphne LaDue was recently invited to speak on her research at the National Academy of Sciences in a workshop on Advancing Risk Communication with Decision-Makers for Tropical Cyclones. She was one of several non-tropical cyclone researchers the Board on Atmospheric Sciences asked to share research that might inform this topic. Dr. LaDue’s research focuses mainly on how emergency managers and other local officials make decisions prior to a forecasted severe weather event. She also briefly mentioned some results from her collaboration with structural and wind engineers wherein she spoke with people who had directly experienced a tornado.
  • December 19, 2022: CAPS Director, Dr. Ming Xue, was officially honored last week at the American Geophysical Union (AGU) Fall Meeting for his election to Fellow of AGU, for "Pioneering work that enables the understanding of severe and storm-scale weather as well as Earth's atmosphere." Only one in a thousand among AGU members are elected to become its fellow each year. Here is the award ceremony video recording.
