Peter Lauritzen (CGD) started his postdoc by co-authoring a review chapter on "Finite-Volume Methods in Meteorology" for a handbook on numerical methods used in the atmosphere and oceans (co-editor is Dr. J. Tribbia, NCAR). This motivated a detailed stability analysis of finite-volume advection schemes permitting long time steps that has been published in Monthly Weather Review. This work was also presented as a poster at the European Geosciences Union (EGU) General Assembly 2007 where it earned the European Geophysical Union Young Scientists Outstanding Poster Paper (YSOPP) Award.

Peter has, in collaboration with IMAGe, also developed a conservative remapping package for mapping fluxes and state variables to and from the regular latitude-longitude and cubed-sphere grid. Until recently there existed no higher-order method for remapping conservatively between spherical grids. The algorithm is based on the cascade interpolation method that splits the two-dimensional integral into two one-dimensional problems. This allows for the efficient application of higher-order remapping methods. The algorithm is being published in Monthly Weather Review (in press). Currently Peter is collaborating with IMAGe in order to contribute to the development of a new dynamical core based on the Discontinuous Galerkin method (HOMME project).
