þ7#ËxËGGGGGUUUUU _ ii>§xU ?N*xGN?NNxNNNNNNFIVE NEW NCAR SCIENTISTS NAMED In its quarterly meeting 13Ð14 July, the UCAR Board of Trustees approved the appointments of five NCAR researchers as senior scientists. Chosen from within NCAR to provide the center with long- term scientific leadership, senior scientists are selected on the basis of individual competence in research and in other activities that enhance NCAR's interaction with scientists elsewhere. The position is analogous to that of full professor at a tenure-granting university. The new senior scientists are Ron Errico, Climate and Global Dynamics Division (CGD). A specialist in development of adjoint climate models, Ron came to NCAR in 1979 as a postdoctoral fellow. He earned his bachelor's degree in physics at the University of Arizona and his Ph.D. at the Massachusetts Institute of Technology, receiving MIT's Carl Gustav Rossby Award for best meteorology thesis in 1980. Ron's research interests include establishment of the basis, limitations, and methodology for initializing global and mesoscale models; evaluation of data assimilation systems; and investigation of the fundamental processes affecting gravity waves. Ron is an adjunct professor of meteorology at the University of Utah and an adjunct associate professor of meteorology at Colorado State University and the University of Oklahoma. He also has developed a variety of initialization and verification techniques for the NCAR-Penn State mesoscale model. Ron was nominated for the NCAR Outstanding Publication Award in 1990 and received honorable mention last year. Rick Katz, Environmental and Societal Impacts Group (ESIG). Rick has served as ESIG's deputy head for six years. His specialties include the application of statistics to atmospheric and related sciences, the use of decision-making models to value imperfect weather information, and statistical issues relating to the assessment of climate's impact on society. A probabilistic model devised by Rick is used widely for representing time series of daily precipitation. Rick completed his bachelor's degree in mathematics at the University of Virginia in 1970 and his doctorate in statistics at Pennsylvania State University in 1974. He has been at NCAR since 1975, except for a position at Oregon State University between 1979 and 1983. Rick has contributed to several United Nations programs, including the Intergovernmental Panel on Climate Change (IPCC), and is a contributing editor of Current Index to Statistics. Keith MacGregor, High Altitude Observatory (HAO). Keith's research interests include the structure of the solar interior and atmosphere; the life cycle of stellar systems, cool stars, and the sun; trends in solar and astrophysical magnetohydrodynamics and radiative processes; and solar and stellar winds. He came to HAO in 1981 after positions with the Harvard/Smithsonian Center for Astrophysics and the Enrico Fermi Institute, University of Chicago. Keith has chaired the HAO Visitors and Graduate Students Committee for the past two years. He has served on a number of peer-review panels for the National Aeronatics and Space Administration and organized several conference sessions at international solar meetings. Keith earned his bachelor's degree at Cornell University and, in 1977, his doctorate at MIT. Piotr Smolarkiewicz, Mesoscale and Microscale Meteorology Division (MMM). A scientist in MMM since 1983, Piotr came to NCAR's Advanced Study Program in 1981 following completion of his doctorate in physics at the University of Warsaw, Poland. His work has focused on development of numerical methods for solving fluid problems, as well as on numerical studies of the dynamics of small- and mesoscale atmospheric flows. Piotr received NCAR's Outstanding Publication Award for 1988 and earned an honorable mention in 1987; this year he became an editor of Monthly Weather Review. He has taught classes on numerical methods for fluids at numerous U.S. research centers and has presented over 50 invited seminars through the United States and Europe. Tom Wigley (Climate and Global Dynamics Division). Director of UCAR's Office for Interdisciplinary Earth Studies for the past year, Tom moves to a 50-50 NCAR/UCAR appointment this fall. He received his Ph.D. in 1967 at the University of Adelaide in mathematical physics after training as a meteorologist and working as a research scientist in Australia's weather service. Tom served on the faculty of the University of Waterloo, Ontario, Canada, from 1967 to 1975, then headed the Climatic Research Unit, University of East Anglia, England, from 1978 to 1993. Tom's interests includes data analysis, climate impacts, paleoclimatology, and the modeling of climate, sea level, and the carbon cycle. He has served as a lead author in four major reviews of the greenhouse problem, including the 1990 and 1992 IPCC reports. Tom is a member of Academia Europaea and is listed in the 1993-94 edition of Who's Who in the World. u ŸJ¤bîáù«®‚ÿÿÿÿÿðÿð€ •Telneta/ȧ›÷©ÂùÅ({˜ÿÿÿÿÿøÿð€• Word 5.1a =x¨…•íªINB©$!ÿÿÿÿÿøÿï逕V ¾h¼bËÎú @ aŸå1y¹fªô<~½û9ÈFˆË ;<ƒÍ\¢æ , t À  K Ž × ã ä ) t Á  I ‰ Í  R Õ"#g¤à)h­ò7yºÿ_©í2|¼þF‹Óc¦ÉÊËûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûV SN copy  ðhÞËËÎ Ë  !"Ð×áèíôöøþ Ó 69Û:~HHÚ(ÿáÿáùEG(üHHÚ(d'@=à/Р ÐRPalatino€€€E[üEËü
