    Jule Charney's Influence Norman A. Phillips National Weather Service, NOAA on Meteorology' Washington, D.C. 20233 The opportunity to address the Society on the contributions of Jule Charney to our science is an honor of the highest rank, and I thank you for this invitation. I will try to capture for you a meaningful impression of the extent to which our common undertaking has been influenced by this man (Fig. 1). Let me begin by recalling three historical contexts. The first of these is January 1,1917. Jule is born on this day in San Francisco, to Stella and Ely Charney. Five thousand miles away in Bergen, Norway, Vilhelm Bjerknes and his collabor- ators are developing the concepts of fronts and air masses. Some distance south of Bergen, Lewis Richardson is trans- porting wounded soldiers with the Friends Ambulance Corps. In spare moments, he is working on his monumental formulation of what is now called numerical weather prediction. My second context is around 1940. Jule had entered the University of California at Los Angeles in the mid-thirties, and is now a graduate student there in mathematics. UCLA is expanding, and Jacob Bjerknes and Jrirgen Holmboe ar- rive about this time. (A few years earlier, Bjerknes had pub- lished an important paper on long waves. In 1939, while he was at M.I.T., Carl Rossby published his well known model FIG. 1. A picture of Jule Charney (left), with E. Lorenz, taken in of long waves. These events are unknown to Jule.)

This model can be regarded as a prototype of a future NASA Earth modeling system intended to unify development activities cutting across various disciplines within the NASA Earth Science Enterprise. 1 1. Introduction NASA’s goal for an Earth modeling system is to unify the model development activities that cut across various disciplines within the Earth Science Enterprise. Applications of the Earth modeling system include, but are not limited to, weather and chemistry-climate change predictions, and atmospheric and oceanic data assimilation. Among these applications, high-resolution global weather prediction requires the highest temporal and spatial resolution, and hence demands the most capability of a high-end computing system. In the continuing quest to improve and perhaps push to the limit of the predictability of the weather (see the related side bar), we are adopting more physically based algorithms with much higher resolution than those in earlier models. We are also including additional physical and chemical components that have not been coupled to the modeling system previously. As a comprehensive high-resolution Earth modeling system will require enormous computing power, it is important to design all component models efficiently for modern parallel computers with distributed-memory platforms.

  • Ensemble Forecasting and Data Assimilation: Two Problems with the Same Solution?
    Ensemble forecasting and data assimilation: two problems with the same solution? Eugenia Kalnay(1,2), Brian Hunt(2), Edward Ott(2) and Istvan Szunyogh(1,2) (1)Department of Meteorology and (2)Chaos Group University of Maryland, College Park, MD, 20742 1. Introduction Until 1991, operational NWP centers used to run a single computer forecast started from initial conditions given by the analysis, which is the best available estimate of the state of the atmosphere at the initial time. In December 1992, both NCEP and ECMWF started running ensembles of forecasts from slightly perturbed initial conditions (Molteni and Palmer, 1993, Buizza et al, 1998, Buizza, 2005, Toth and Kalnay, 1993, Tracton and Kalnay, 1993, Toth and Kalnay, 1997). Ensemble forecasting provides human forecasters with a range of possible solutions, whose average is generally more accurate than the single deterministic forecast (e.g., Fig. 4), and whose spread gives information about the forecast errors. It also provides a quantitative basis for probabilistic forecasting. Schematic Fig. 1 shows the essential components of an ensemble: a control forecast started from the analysis, two additional forecasts started from two perturbations to the analysis (in this example the same perturbation is added and subtracted from the analysis so that the ensemble mean perturbation is zero), the ensemble average, and the “truth”, or forecast verification, which becomes available later. The first schematic shows an example of a “good ensemble” in which “truth” looks like a member of the ensemble. In this case, the ensemble average is closer to the truth than the control due to nonlinear filtering of errors, and the ensemble spread is related to the forecast error.

  • Atmospheric Modeling, Data Assimilation and Predictability
    This page intentionally left blank Atmospheric modeling, data assimilation and predictability This comprehensive text and reference work on numerical weather prediction covers for the first time, not only methods for numerical modeling, but also the important related areas of data assimilation and predictability. It incorporates all aspects of environmental computer modeling including an historical overview of the subject, equations of motion and their approximations, a modern and clear description of numerical methods, and the determination of initial conditions using weather observations (an important new science known as data assimilation). Finally, this book provides a clear discussion of the problems of predictability and chaos in dynamical systems and how they can be applied to atmospheric and oceanic systems. This includes discussions of ensemble forecasting, El Ni˜no events, and how various methods contribute to improved weather and climate prediction. In each of these areas the emphasis is on clear and intuitive explanations of all the fundamental concepts, followed by a complete and sound development of the theory and applications. Professors and students in meteorology, atmospheric science, oceanography, hydrology and environmental science will find much to interest them in this book which can also form the basis of one or more graduate-level courses. It will appeal to professionals modeling the atmosphere, weather and climate, and to researchers working on chaos, dynamical systems, ensemble forecasting and problems of predictability. Eugenia Kalnay was awarded a PhD in Meteorology from the Massachusetts Institute of Technology in 1971 (Jule Charney, advisor). Following a position as Associate Professor in the same department, she became Chief of the Global Modeling and Simulation Branch at the NASA Goddard Space Flight Center (1983–7).

  • A Semi-Implicit Modification to the Lorenz N-Cycle Scheme and Its
    JUNE 2016 H O T T A E T A L . 2215 A Semi-Implicit Modification to the Lorenz N-Cycle Scheme and Its Application for Integration of Meteorological Equations DAISUKE HOTTA Japan Meteorological Agency, Tokyo, Japan, and University of Maryland, College Park, College Park, Maryland EUGENIA KALNAY University of Maryland, College Park, College Park, Maryland PAUL ULLRICH Department of Land, Air and Water Resources, University of California, Davis, Davis, California (Manuscript received 23 September 2015, in final form 13 January 2016) ABSTRACT The Lorenz N-cycle is an economical time integration scheme that requires only one function evaluation per time step and a minimal memory footprint, but yet possesses a high order of accuracy. Despite these advantages, it has remained less commonly used in meteorological applications, partly because of its lack of semi-implicit formulation. In this paper, a novel semi-implicit modification to the Lorenz N-cycle is proposed. The advantage of the proposed new scheme is that it preserves the economical memory use of the original explicit scheme. Unlike the traditional Robert–Asselin (RA) filtered semi-implicit leapfrog scheme whose formal accuracy is only of first order, the new scheme has second-order accuracy if it adopts the Crank– Nicolson scheme for the implicit part. A linear stability analysis based on a univariate split-frequency os- cillation equation suggests that the 4-cycle is more stable than other choices of N. Numerical experiments performed using the dynamical core of the Simplified Parameterizations Primitive Equation Dynamics (SPEEDY) atmospheric general circulation model under the framework of the Jablonowski–Williamson baroclinic wave test case confirms that the new scheme in fact has second-order accuracy and is more accurate than the traditional RA-filtered leapfrog scheme.

  • Bibliography of Recent Literature in the History of Meteorology Twenty Six Years, 1983-2008
    History of Meteorology 5 (2009) 23 Bibliography of Recent Literature in the History of Meteorology Twenty Six Years, 1983-2008 Brant Vogel Papers of John Jay Columbia University The following is a bibliography of recent secondary literature in the history of meteorol- ogy, broadly conceived. It is presented in chronological order a) to illustrate the growth of his- tory of meteorology as field in the throes of self-definition, and b) because an artificial schema, whether based on subject, region, period, or discipline, would fail in the face of the diversity of the materials represented. It is intended as a tool for students entering the field, a refresher for those already in it, and a reference for historians in other fields.1 History of the Project The bibliography project began in November 2003 at the History of Science Society An- nual Meeting in Cambridge, MA. James Fleming2 organized a session and a subsequent wildcat dinner for ICHM members. At the session, and afterwards, Fleming told me that the IUHPS had requested that its commissions produce bibliographies for the World History of Science Online Project. I offered that I had already compiled a fairly large bibliographic database while com- pleting my dissertation.3 Because of what I found to be the paucity of literature in the historiog- raphy of meteorology when I started my dissertation research, I had gathered everything I could find. Fleming suggested making a more formal project of it. As there were other bibliographic resources for older material, we decided that twenty years of recent historiography would be the most useful.
