Phasing

This important operation is completed twice a year to "phase" the ALADIN code with its "mother" code ARPEGE (see history of cycles and phasing team and some statistics on phasing effort). The ALADIN code is following the ARPEGE one in its permanent evolution (see history of ALADIN cycles). This is due mainly to the technical evolution of calculating machines (CDC, CRAY 2, CRAY C90, FUJITSU, NEC...) which imposes a new adaptation of the code to the new machine properties. The evolution of (…) - Software codes

The ALADIN System

Patricia — 2002-09-11T18:17:00Z

ALADIN was entirely built on the notion of compatibility with its Â« mother Â» system, IFS/ARPEGE. The latter, a joint development between the European Centre for Medium-Range Weather Forecasts ([ECMWF->http://www.ecmwf.int) and MÃ©tÃ©o-France , was only meant to consider global Numerical Weather Prediction applications ; hence the idea, for ALADIN, to complement the IFS/ARPEGE project with a limited area model (LAM) version, while keeping the differences between the two softwares as small (…) - Software codes

Configurations

The ALADIN configurations Nine are currently fully validated (the number is likely to increase in the near future, given the momentum of the project) : e923 : the creation of the Â« geographical Â» conditions for any given geometry of the LAM, anywhere on the globe ; e927/ee927 : the creation of initial and/or lateral boundary conditions starting from an ARPEGE or an ALADIN file ; e701 : the optimal interpolation analysis module nick-named CANARI ; e001 : the model integration itself (…) - Software codes
