Wind dynamical adaptation (info: margarida.belo@meteo.pt & pedro.sousa@meteo.pt) Wind dynamical adaptation is being validated for 3 different domains of Portugal. Tests have been performed as case studies under different synoptical situations. The temperature dynamical adaptation has been tried as well. Preliminary conclusions are: results are good for the wind field (in opposition to direct fields); however, incresed value over the direct wind output fields depend on the synoptic situation; we will need an objective verification to understand if results are better with 15 or 26 vertical levels; time step and adaptation step seem to be irrelevant for this tool on the studied cases.

ALADIN/Portugal on AMD 64 dual core processors (info: joao.ferreira@meteo.pt) With the new models generation of the ALADIN community NWP challenges are grown for countries with few resources. The new computer requirements of the community trigger local strategies based on low price solutions[1]. Recently, the PaiPix[2]/IM Linux distribution has 126
een locally implemented as an optimised development environment for NWP activities. This work consisted in creating the appropriate Debian packages and patches for the ECMWF applications using the Debian Sarge distribution and the Linux kernel 2,6. The PaiPix work also integrated the database tools currently being developed at IM, or TIDB2[3]. Although this platform could be directly booted from a DVD (live) it has been locally installed on the hard disk of each AMD64 PC available for each working position. Basic tests with ALADIN source code have now allowed the installation of the local version of ALADIN/Portugal on a private 6 AMD dual core PC cluster under the PaiPix operating system: gmkpack has been used on the installation of CY29T2. Foreseen tests will increase power of this cluster with the compatible AMD64 PC’s of each NWP working position. At the end conclusions will be taken about the suitable design of the best quality/price computer platform solution for operational and development NWP activities.
