Mathematics of the Weather: Polygonal Spline Local-Galerkin Methods on Spheres de Jürgen Steppeler

Mathematics of the Weather: Polygonal Spline Local-Galerkin Methods on Spheres: Springer Atmospheric Sciences

Autor Jürgen Steppeler, Jinxi Li
en Limba Engleză Paperback – 26 oct 2023


"Mathematics of the Weather” details the mathematical techniques used to create numerical models of the atmosphere. It explains methods which are currently considered for practical use in models for the exaflop computers (10**19 operations per seconds). This book is a guide to developing and modifying the mathematical methods used in such models. This includes Implementations in spherical geometry. The books also concentrates on elements of Numerical Weather Predication (NWP) and Computational Fluid Dynamics (CFD).

Notă biografică

​Jurgen Steppeler obtained a PhD in  theoretical particle physics and mathematical Physics at the University of Goettingen, Germany. Then he joined the Research Departement of DWD in Offenbach as a specialist for mathematical methods for atmospheric models. During the 50 years since joining DWD he witnessed weather forecasts changing from a form of art involving some guesswork to reliable forecasts entirely produced by computers. He spent long times at other institutes, for example several visits to China. Other vistits were 8 years at ECMWF (European Center for Medium range Forecasts) 1 year at NCEP (National Center or Environmental Prediction, Washington D.C.) and a Series of more than 20 visits of one month each at FSU and NCAR, Boulder. He is a faculty member of University Bonn (Germany), where he supervised a number of PhD theses on mathematical methods in atmospheric models and gave lectures both on numerical methods and about the  cooperation between Universities and  operational institutes. He was Editor and served as reviewer for many scientific Journals. He was project manager of DWD's model LM, which since then was renamed COSMO and ICON and still is part of the numerical forecasting system of DWD. He founded a company to produce software for the cooperation of individuals and institutes on spherical grids and cut cells. 

Jinxi Li is an Associate Professor at International Center for Climate and Environment Sciences, Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences. He has 6 years’ experience in developing numerical methods and dynamical framework of atmospheric models.  
Jinxi earned his Bachelor of Science degree in Mathematics and Applied Mathematics at Hunan Normal University in 2011. He was awarded his doctoral degree in 2016 from the University of Chinese Academy of Sciences. After graduation, he conducted a five-year postdoctoral research in IAP for the development of adaptive mesh atmospheric models collaborated with AMCG, Imperial College London and DAMTP, University of Cambridge.
