TL;DR: ERA-Interim as discussed by the authors is the latest global atmospheric reanalysis produced by the European Centre for Medium-Range Weather Forecasts (ECMWF), which will extend back to the early part of the twentieth century.
Journal ArticleDOI

TL;DR: In this article, a comparison of 8 regional atmospheric model systems was carried out for a three-month late summer/early autumn period in 1995 over the Baltic Sea and its catchment area.

TL;DR: In this paper, the reference configuration of the convection-permitting numerical weather prediction (NWP) model HARMONIE-AROME, which is used for operational short-range weather forecasts in Denmark, Estonia, Finland, Iceland, Ireland, Lithuania, the Netherlands, Norway, Spain, and Sweden, is described.

AROME-MetCoOp: A Nordic Convective-Scale Operational Weather Prediction Model
Malte Müller,Mariken Homleid,Karl-Ivar Ivarsson,Morten Køltzow,Magnus Lindskog,Knut Helge Midtbø,Ulf Andrae,Trygve Aspelien,Lars Berggren,Dag Bjørge,Per Dahlgren,Jørn Kristiansen,Roger Randriamampianina,Martin Ridal,Ole Vignes +14 more
TL;DR: In this paper, specific modifications and updates that have been made to suit advanced high-resolution weather forecasts over the Nordic regions are described, including modifications in the surface drag description, microphysics, snow assimilation, as well as an update of the ecosystem and surface parameter description.
Journal ArticleDOI
Three-dimensional variational data assimilation for a limited area model : Part II: Observation handling and assimilation experiments
Magnus Lindskog,Nils Gustafsson,Beatriz Navascues,Kristian S. Mogensen,Xiang-Yu Huang,Xiaohua Yang,Ulf Andrae,Loïk Berre,Sigurdur Thorsteinsson,Jarmo Rantakokko +9 more
TL;DR: In this article, a 3D-Var data assimilation scheme for the HIRLAM forecasting system is described, which is based on the minimisation of a cost function that consists of one term, J b which measures the distance between the resulting analysis and a background field, in general a short-range forecast, and another term,J o which measured the distance from the analysis and the observations.
