WISE

Warner Internship for Scientific Enrichment

In honor of Dr. Warner's personal commitment to the education and mentoring of so many students and professionals in the atmospheric sciences, a new Warner Internship for Scientific Enrichment (WISE) is being established to provide support to graduate student education and outreach. The WISE internship fund is funded through donations. It is anticipated that the first WISE intership will be awarded in the fall of 2012. Details on the internship will be posted at this web site as they become available.

The Warner Memorial Symposium

December 2nd, 2011 | NCAR Foothills Laboratory, Boulder, Colorado

Family, friends and colleagues gathered at the National Center for Atmospheric Research on December 2, 2011 for the Thomas T. Warner Memorial Symposium. The purpose of the symposium was to pay tribute to the scientific career and to celebrate the rich life of Dr. Warner. The symposium consisted of invited oral presentations focused on topics related to the areas of atmospheric modeling that represent Dr. Warner's career, including desert meteorology, numerical weather and climate prediction, quality assurance in the atmospheric modeling process, and Tom's extraordinary role as a mentor in the lives of his colleagues. The symposium was hosted jointly by NCAR's Research Applications Laboratory, Penn State Department of Meteorology and University of Colorado Atmospheric and Oceanic Sciences.

UCAR Magazine featured an article about the symposium in the Monday, January 23, 2012 edition: "Modeler, mentor, friend."

Videos and slide presentations from the symposium are available for download under the "Symposium" tab above.

FACILITIES DEVELOPMENT:

Since 1980, the Penn State/NCAR mesoscale model has been developed into a research and operational meteorological modeling system that is used and recognized worldwide. A large fraction of this development work has been accomplished at Penn State under the direction of T. Warner. The following statistics serve to emphasize the growth of this facility in the last decade, and the degree to which it represents a national and international research tool.

• Over 90 students have used the modeling system during their M.S. and Ph.D. research (1980-2011).

• Over 25 university, government and private facilities in the United States utilize the modeling system (1980-2011) (e.g., Colorado State University, General Motors Research Laboratory, Argonne National Laboratory, NASA Ames Research Center).

• Over 20 research laboratories outside of the United States employ the modeling system (1980-2011) (e.g., University of Lanzhou, People's Republic of China; University of Cologne, Germany; Norwegian Meteorological Institute, Norway; Tel Aviv University, Israel).

• Over 100 articles in peer-reviewed scientific journals have resulted from the model's use in and outside of the U.S. (1980-2011).

• The model is used for real-time weather prediction at Penn State, and the forecasts are archived in real-time at NCAR for use by the academic and research community nationwide. At Penn State, the forecasts are used for research, teaching and public service (1989-2011).
