Informazioni sull'autore

Dr. Sivaramakrishnan Lakshmivarahan (Varahan, for short) joined the University of Oklahoma in the fall of 1978 where he is currently a George Lynn Cross Research Professor at the School of Computer Science. From 1973-1978 he has held postdoctoral and faculty positions at Brown University, Yale University and Indian Institute of Technology, Madras, India. He obtained his PhD in 1973 from the Indian Institute of Science in Bangalore, India. He is the author/coauthor of 5 books and has published extensively in a number of areas including Learning Algorithms, Parallel Architecture and Algorithms, Dynamic Data Assimilation and Computational Finance. He has supervised 30 PhD dissertations and 42 MS Theses. He is Fellow of the IEEE and a Fellow of the ACM and has won numerous awards- Regents award for Superior Teaching and Regents Award for Research and Creative Activity.  He has held short-term visiting appointments at leading academic centers in Japan, Taiwan, China, Germany, England, Canada, Mexico and USA. He has been inducted into the Oklahoma Higher Education Hall of Fame in 2014.    

John Lewis’ scientific training is in geophysics and meteorology along with an interest and training in applied mathematics, especially mathematical physics with concentration in variational mechanics. Dr. Lewis was fortunate to be trained under George Platzman at University of Chicago and Yoshikazu Sasaki at University of Oklahoma and he has worked for private industry (Shell Oil Co., exploration seismology), operational weather prediction centers (U. S. government and U. S. Navy), academia (University of Illinois), and government science (as a director of research and as a research meteorologist). In the early 1990s, Dr. Lewis came under the influence of historian of science Duane Roller and began contributing to the history of science along with other work in meteorology. He has supervised doctoral dissertations of 10 students, contributed to over 150 research papers, and has published a book with another nearly completed on the history of science. Dr. Lewis was elected Fellow of the American Meteorological Society in 2007.      

Dr. Rafal Jabrzemski has joined the Oklahoma Climatological Survey in 1999, where he works as a software engineer developing applications related to quality assurance of meteorological data from the Oklahoma Mesonet, and decision support applications that use meteorological data such as agrometeorological models and Oklahoma Fire Danger Model. In 2014, he defended his Ph. D. dissertation: “Application of the Forward Sensitivity Method to Data Assimilation of the Lagrangian Tracer Dynamics”       

Dalla quarta di copertina

This book introduces the reader to a new method of data assimilation with deterministic constraints (exact satisfaction of dynamic constraints)—an optimal assimilation strategy called Forecast Sensitivity Method (FSM), as an alternative to the well-known four-dimensional variational (4D-Var) data assimilation method. 4D-Var works with a forward in time prediction model and a backward in time tangent linear model (TLM). The equivalence of data assimilation via 4D-Var and FSM is proven and problems using low-order dynamics clarify the process of data assimilation by the two methods. The problem of return flow over the Gulf of Mexico that includes upper-air observations and realistic dynamical constraints gives the reader a good idea of how the FSM can be implemented in a real-world situation.
