ALADIN developments in Toulouse during the third quarter of 1999
From a statistical point of vue, the comments of the previous quarter is
still available ...
"During the last months, GMAP offices have given to all ALADIN visitors
and GMAP people the impression that they were less crowded than usual.
The effort in Toulouse during this quarter was the smaller one for years
!..." ...this was for the second quarter ... for the third quarter
it is even worse !..
"Less than 30 persons (and less than 60% of visitors) coming from
8 countries on only 3 different fundings" for the second quarter...
and less than "less" for this quarter. Many thanks to Elisabeth
Gerard who joined ALADIN team in GMAP (she replaces Patrick Le Moigne)
... without her, statistics would have been even worse !...
... but with ALATNET (if ALATNET runs of course), ... it will be much
better !..

A new orography in ARPEGE/ALADIN
Thanks to the work of two students, Philippe Marguinaud and Youssef Moudden,
for the ARPEGE part and Vladimir Ivanovici for the ALADIN part and the
diagnostic tools, a new parameterization of the envelope orography has
been introduced. It remains close to the mean orography at the largest
scales so as to better preserve the global mass, and close to the previous
envelope at small scales so as to keep the blocking effect of enhanced
mountains. This is achieved in configuration 923 by adding a spectral term
to the cost function used in the minimization of orography. André
Simon is currently testing whether this new orography could be successfully
coupled with the "lift" parameterization proposed by F. Lott and already
used in the ARPEGE/Climat code.
