Hamburg, 7 July 2009.Today the Wladimir Peter Köppen Award was presented for the first time by the KlimaCampus of the University of Hamburg. The award, which carries a value of 5,000 Euros, goes to Dr. Hui Wan of the Max Planck Institute for Meteorology (MPI-M)for her excellent dissertation in numerical weather and climate modelling.
Prof. Dr. Klaus Fraedrich emphasized that the jury was particularly impressed by the innovative numerical methods applied by Hui Wan. They represent an important contribution to the next generation of predictive models.The young scientist was born in the Province of Hubei in China. She studied Atmospheric Physics at the "Chinese Academy of Sciences" in Beijing and successfully applied for a Doctoral Scholarship at the ‚International Max Planck Research School on Earth System Modelling’ (IMPRS-ESM) in the year 2004. In August of 2005 she started her work in Dr. Marco Giorgetta’s group on ‚Global Climate Modelling’ at the Max Planck Institute for Meteorology. She received her Doctoral Degree „summa cum laude“ from the University of Hamburg on 30 January 2009. She is now continuing her research work at the KlimaCampus in Hamburg.
New Methods for weather and climate predictionThe work done by Dr. Hui Wan is part of the „ICON“ model development project of the Max Planck Institute for Meteorology together with the German Weather Service.Hui Wan extended a two-dimensional shallow water model, which calculates currents in a single layer, into a three-dimensional dynamical model. In this new model the atmosphere is divided into several layers of triangular cells. In each of these cells, temperature and wind, and with this the inflowing and outflowing air mass is calculated. Of particular interest are the methods in themselves. They should guarantee elementary conservation characteristics, cost as little computer time as possible but give sufficient details and precision regarding the currents. Hui Wan´s work contributes significantly to the understanding of the numerical methods in the ICON model. The numerical model developed by her forms the core of the next ICON atmosphere and climate model which will be used in the future for more detailed prognoses than are possible at present.
