- Abstract
The set-up and performance of the regional reanalysis for Europe with the HIgh-Resolution Limited-Area Model (HIRLAM) to a 3D grid-mesh with 22 km resolution for the years 1989-2010 have been presented in Part 1. This part describes how the 3D dataset is further downscaled and used as input for an analysis of a number of surface-related parameters: 2 m temperature, minimum and maximum daily temperatures, 10 m wind, and daily precipitation. The analysis is done on a 2D grid-mesh with 5 km grid spacing using the MESoscale ANalysis system (MESAN) for temperature and precipitation and a dynamical adaptation method (DYNAD) for the 10 m wind. Results from MESAN and DYNAD are compared with observations and the HIRLAM 3D-Var reanalysis. A couple of cases with severe weather are studied to illustrate how such events are represented in the analyses. The comparisons show statistically significant added value in comparison to the HIRLAM reanalysis.
