ABOUT CAPS 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 wants 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. NEWS 5/2008. CAPS is conducting a unprecedented real time storm-scale ensemble forecast experiments for the second year, which include the assimilation of data from over 120 WSR-88D radars. Daily 10-member 4-km ensemble and 2-km high-resolution deterministic forecasts of 30 hour long are being produced using the WRF model for nearly the entire continental U.S., using a supercomputer at PSC. The radar data analyses are performed using the ARPS 3DVAR and cloud analysis system on both 4 and 2 km grids. This is part of the NOAA Hazardous Weather Testbed (HWT) 2008 Spring Experiment and is a collaboration among CAPS, SPC, NSSL, PSC with assistance and participation of EMC and other NCEP Centers. Xue et al. (2007) and Kong et al. (2007) outlines the 2007 experiments. This project is partially supported by our CSTAR grant. 5/2008. CAPS is producing daily 6-hour forecasts at 1-km horizontal resolution using ARPS 3DVAR and ARPS, assimilating WSR-88D and/or CASA radar data, on days storms exist within the CASA network. Low-level wind analyses are also produced every 5 minutes. Realtime CASA radar display is at SOCC. These forecasts and analyses use a supercomputer at OSCER. This is a project of CASA, an NSF Engineering Research Center. 6/2007. CAPS submited a set of papers to the 18th Conf. on Numerical Weather Predicton and 33rd Int. Conf. on Radar Meteorology. 5/2007. CAPS is conducting unprecedented real time storm-scale ensemble forecast experiments. Preliminary results are reported in Xue et al. (2007) and Kong et al. (2007). 5/2007. CAPS is producing daily 6-hour forecasts at 1-km horizontal resolution using ADAS and ARPS, assimilating WSR-88D and/or CASA radar data, on days storms exist within the CASA network. These forecasts use a supercomputer at OSCER. This is a project of CASA, an NSF Engineering Research Center. 4/2007. Former CAPS Ph.D. student and current post-doctoral scientist, Mingjing Tong won OU Provost's Prize for Ph.D. Dissertation in Science and Engineering. Her dissertation research was advised by Dr. Ming Xue. 4/2007. CAPS director, Dr. Ming Xue, won OU Regent's Award for Superior Research and Creative Activities and College of Atmospheric and Geographical Sciences Dean's Award for Outstanding Performance in Research. 4/2007. CAPS was awarded a highly rated grant by the NOAA CSTAR Program entitled "A Partnership to Develop, Conduct, and Evaluate Realtime High-Resolution Ensemble and Deterministic Forecasts for Convective-scale Hazardous Weather
Dr. Douglas Lilly, the founding Director of CAPS and member of National Academy of Sciences, visited OU from his retirement home in Nebraska and gave the 12th Annual Gal-Chen Memorial Lecture on Nov. 14, 2006. A picture of him with Dr. Ming Xue. CAPS celebrated, on October 27, 2006, 17 year's outstanding leadership by Dr. Kelvin Droegemeier, as CAPS Director, and congratulating him for his appointment to the position of Associate Vice President of Research of the University of Oklahoma (photos coming soon). Dr. Ming Xue, former Scientific Director, succeeded Dr. Kelvin Droegemeier as the new CAPS Director on July 1, 2006. Dr. Droegemeier will be the Director Emeritus. CAPS completes a highly successful NSF project "Optimal Utilization and Impact of Water Vapor and Other High Resolution Observations in Storm-Scale QPF". CAPS leads an NSF Large Information Technology Research (ITR) grant, Linked Environments for Atmospheric Discovery (LEAD), which is creating a cyberinfrastructure for mesoscale meteorology research and education. CAPS leads the University of Oklahoma's efforts in CASA as a major partner in the NSF Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere (CASA).
