1. INTRODUCCIÓN
The NWP operational and research activities undertaken during 2005 and 2006 in INM are
summarized below. Operational activities are mainly related to the implementation of
HIRLAM 6.1.4 to the CRAY X1E, upgraded to the final configuration in 2005. Recent
verification results are included as well as one example of verification against the
precipitation measured by the INM pluviometric network. The wave model WAM has also
been ported to the new platform. One ocean current model uses as input the HIRLAM HNR.
Research activities cover those in Dynamics, Data Assimilation, Physical parametrizations
and Predictability. A detailed description of the Short Range Ensemble Prediction System
under development in INM is given in the contribution ‘Recent experiences with the INMmultimodel
EPS scheme’ in this volume.
2. OPERATIONAL ACTIVITIES
2.1 Computer resources.
The characteristics of the CRAY X1E, whose final acceptance took place in
December 2005 are:
• 15 nodes, 8 MSP’s each node
• 4 SSP’s each MSP
• 320 Gb memory
• 2.3 TF peak performance
The machine is quite compact as it can be seen in fig. 1, which also includes the
scheme of the multistream processors (MSP).
2.2 HIRLAM operational in INM.
The current HIRLAM version installed in the CRAY X1E is the 6.1.4 one working
in three configurations at the areas shown in fig 2 and fig 3. Non rotated areas are also
included corresponding to versions still running in the CRAY SV1. The configuration and
resolutions are:
• ONR
– 0.16 deg latxlon, 40 levels
– 72 hours forecast, 4 times a day
– 3DVAR
– BC’s from ECMWF
• HNR and CNN
– 0.05 deg latxlon, 40 levels
– 36 hours forecast, 4 times a day
– 3DVAR
– BC’s from ONR
The integration areas of the WAM wave operational model are displayed in fig 4 to
7. ESEOO is an Spanish interdepartamental project for operational oceanography. Its ain
is to run operationally an ocean limited area model to prepare current forecast. Table I
