    temperature through the reflection of sunlight the absorption of infrared radiation from the surface and the emission of radiation to the surface as part of greenhouse effect Since individual clouds have a spatial scale of less than 10 km that is much smaller than the conventional grid size of several hundred kilometers in climate and weather prediction models they must be quantitatively formulated in terms of resolved variables in the prognostic equations of temperature moisture and wind Deriving such formulations for convection and clouds has been a major challenge for the climate modeling community due to the lack of observations of cloud and microphysical properties To address this problem my collaborators at NCAR and I have developed a cloud resolving model CRM which resolves individual clouds but covers a large horizontal domain to generate cloud scale datasets The diagnostic and theoretical studies applying the high resolution datasets generated by the CRM have lead to the improved representation of convection and cloud radiation interaction in the climate models and the improved simulations of global climate mean state and variability Research Projects Wu X and X Z Liang Co PI 2002 2006 Application of Seasonal CRM Integrations to Develop Statistics and Improved GCM Parameterization of Subgrid Cloud Radiation Interactions DOE ARM Wu X G J Zhang Co PI and R W Arritt Co I 2004 2008 Evaluating the representation and impact of convective momentum transport in CCSM atmosphere model DOE CCPP Wu X and Qilong Min Co I 2008 2011 Understanding and Improving CRM and GCM Simulations of Cloud Systems with ARM Observations DOE ARM Wu X 2009 2012 Effects of Cloud and Radiation Processes on the Global Water and Energy Cycle NSF Teaching Atmosperic Physics I Mteor 341 3 credits Atmosperic Physics II Mteor 342 3 credits Atmosperic Physics Mteor 542 3 credits Recent Refereed Papers Park S and X Wu 2010 Effects of Surface Albedo on Cloud and Radiation Processes in Cloud Resolving Model Simulations J Atmos Sci in press Deng L and X Wu 2010 Effects of Convective Processes on GCM Simulations of the Madden Julian Oscillation J Climate 352 377 Song X X Wu G J Zhang and R Arritt 2008 Understanding the effects of convective momentum transport on climate simulations The role of convective heating J Climate 21 5034 5047 Wu X S Park Q Min 2008 Seasonal variation of cloud systems over ARM SGP J Atmos Sci 65 2107 2129 Wu X and X Li 2008 A review of cloud resolving model studies of convective processes Advances in Atmospheric Sciences 25 202 212 Song X X Wu G J Zhang and R Arritt 2008 Dynamical effects of convective momentum transports on global climate simulations J Climate 21 180 194 Wu X L Deng X Song G Vettoretti W R Peltier and G J Zhang 2007 Impact of a modified convective scheme on the MJO and ENSO in a coupled climate model Geophys Res Lett 34 L16823 doi 10 1029 2007GL030637 Wu X L Deng X Song

    redefinition of emphasis beginning in the early 60s and continuing for over a decade The first major item of analytical instrumentation an X ray diffractometer was purchased in 1960 Dr Roy became Dean of the College of Sciences and Humanities in 1962 and Dr Hussey became department head The following year Dr Lyle Sendlein Iowa State 1963 who had been hired as an instructor in 1961 was promoted to assistant professor and Dr Carl Vondra Nebraska 1963 was appointed assistant professor Approval was given in 1963 for the department to offer a doctoral program without the restriction of a double major Dr Charles Payton Missouri 1963 was given a one year appointment as assistant professor in 1964 Drs Karl Seifert Wisconsin 1963 and Robert Palmquist Wisconsin 1965 were each hired as assistant professor on tenure track in 1965 That same year Dr Thomas died In 1966 Dr Vondra assumed responsibility for the summer field program About this time the department received several grants from NSF for undergraduate traineeships at the field station in Wyoming Research efforts by faculty in the department at that time included land use problems including groundwater and solid waste disposal sedimentological and stratigraphy problems in the Big Horn Basin with emphasis on the environmental setting of units containing fossils of early vertebrates and chemistry and mechanical properties of anorthosites A rock deformation lab was set up in the Botany annex with NSF funds and later transferred to Science I when space for the department was expanded in 1972 During the early to mid 60s the department was heavily involved in upgrading science teaching in the secondary schools Dr Roy became the National Chairman of the Earth Science Curriculum Project ESCP Drs Lemish and Thomas conducted National Science Foundation Summer Institutes on campus for earth science teachers and Dr Hussey conducted NSF sponsored field projects for earth science teachers at the Philmont Boy Scout Ranch in New Mexico Largely as a result of interest in the ESCP and related projects the direction of the department was altered to emphasize the broader aspects of the earth sciences In 1965 meteorology rejoined the department and the name was changed to Department of Earth Science The Meteorology program which had been transferred to the Physics Department in 1945 was suspended in the late 50s when several key faculty went to the University of Arizona Since that time formal instruction in meteorology was done in the Agricultural Climatology program in the Department of Agronomy Interest in atmospheric physics had continued within the Physics Department until 1964 at which time the last meteorologist in Physics resigned Physics requested that the meteorology program be formally dropped from their administrative responsibilities and Dean Roy shifted official responsibility of that program to this department A meteorologist was hired during each of the following two years Dr Gale Biggs Michigan 1965 in 1966 and Dr Douglas Yarger Arizona 1967 in 1967 each with a split appointment between the Department of Earth Science and the Department of Agronomy Dr G Biggs appointment was 50 50 split between the two colleges and Dr Yarger s was 70 Science Humanities 30 Agriculture The Meteorology Program was housed in Curtiss Agricultural Hall along with the Agricultural Climatology Program Dr Gwynne retired in 1967 and another geologist Dr Robert Cody Colorado 1968 was hired Ms Jane Zaring M A Indiana 1966 was appointed as an instructor in geography also in 1967 In 1968 Dr Gale Biggs resigned and Mr Harry Vaughn M S Iowa State 1968 who had been a research associate with the Ames Laboratory and Agronomy since 1963 was hired as an instructor in meteorology with a 25 75 split appointment between Earth Science and Agronomy Mr Vaughn was promoted to assistant professor in 1969 The trend to broaden the department continued in the early 1970s commencing with the appointment of Dr Fred DeLuca Oklahoma 1970 in earth science education Dr DeLuca s appointment was split with the Department of Education in the College of Education The following year Dr Mushtaq Ur Rahman Louisiana State Univ 1960 was appointed associate professor of geography the first faculty member on tenure track appointment trained especially in geography since that subject was originally offered in the department in 1925 Dr Gene Takle ISU 1971 was appointed to fill the assistant professor of meteorology position created when Dr G Biggs resigned Dr Takle s appointment was also split between Earth Science and Agronomy Another meteorologist Dr John Brown MIT 1973 was hired as an assistant professor in 1972 Dr Brown was the first meteorologist with a 100 appointment within the Department of Earth Science In 1972 additional space became available in the east wing of the Science I building when Zoology moved to new quarters Geology and geography moved into these new quarters but meteorology remained in Curtiss Hall with the Ag Climatology program Dr Roy retired as dean in 1972 and returned part time to the department faculty The following year Dr Gwynne died Dr Hussey retired as department head in 1974 and returned to the departmental faculty Dr Bert E Nordlie Chicago 1967 was appointed professor and chairman that same year In 1976 the name was changed to Department of Earth Sciences the addition of the s signifying the plurality of the department At the time of Dr Nordlie s appointment the faculty consisted of 9 5 FTE geologists exclusive of Dr Nordlie 2 45 FTE meteorologists and 2 5 FTE geographers one on tenure track one instructor and one half time temporary position Research among the faculty members included sedimentological and stratigraphic investigations in Wyoming Egypt India Pakistan with emphasis on deposits containing fossils of vertebrates including early hominids Vondra rare earth element distribution studies in massif type anorthosites using facilities at the Ames Lab Research Reactor Seifert land use problems including geologic factors affecting landfill location and operation and groundwater quality Sendlein and Palmquist coal geology at the Iowa coal mine Lemish and Sendlein Equipment and instrumentation included the

  • Alumni reflections | Department of Geological & Atmospheric Sciences
    GSD in Boulder CO I worked at NOAA laboratory for six years Recently I joined a private company for wind forecasting The education and experience during the graduate school at ISU helped build my confidence and were critical in getting and enjoying my work at NOAA Furthermore the excitement about science innovation and progress that I acquired at ISU helped in my decision making to join a private company founded on cutting edge science and become a part of this exciting work While in graduate school I was educated and advised by caring motivated professors that were truly focused on my and other graduate students success They highly encouraged and supported my work and creativity and always focused on my future and how my time at the ISU could prepare me for future career challenges and excitement Once again my experiences opportunities provided education received and friendships gained have continued to be a cornerstone of my professional and personal life It was privilege to be a graduate student at ISU Department for Geological and Atmospheric Science and continues to be a privilege to be an alumnus Mitch Cline B S 2009 M S 2011 Geology The Iowa State Geology Department was my second family during college as I received both my B S and M S degrees in geology from ISU The small class sizes allowed for extensive personal interaction with both my fellow students and professors which stoked my interest in geological processes Looking back being on a first name basis with everyone in the geology department students staff and professors was crucial to my success I enjoyed my undergrad experience so much that I decided to stay and complete an M S in glacial geology While research consumed most of my time during grad school I still managed to teach labs for several courses and become close friends with the troop of highly skilled graduate students that reside at the ISU geology department Most importantly the education I received as both an undergrad and grad student from the Iowa State Geology Department provided the necessary experience and skills to be hired as an environmental consultant with URS Corporation prior to graduation I highly recommend any student considering geology to explore what the Iowa State Geology Department has to offer as recent faculty hires and ever increasing departmental enrollment surely signal greater things yet to come Adriana Heimann M S 2002 Ph D 2006 Geology Pursuing graduate studies in Geology at the Department of Geological and Atmospheric Sciences at Iowa State University was the best experience of my life The professors are excellent and caring and there is camaraderie among graduate and undergraduate students which makes the perfect environment for learning Coming from Uruguay to ISU was therefore a very easy and enjoyable transition My Masters and PhD research in metamorphic petrology and economic geology took me to numerous places including three long trips to Australia along with my advisor Dr Spry Meeting scientists from several universities in Australia
