Geopotential height at 500 hPa (solid line)<br>

The maps show the predominant tropospheric waves (trough or ridge).
They virtually control the ''weather'' (dry, warm / wet, cold) and the long waves 
drive the smaller synoptic waves.
Thus, this upper-level chart illustrates the dynamics of our atmosphere.

  <div class="eI1">Cluster of Ensemble Members:</div>
  <div class="eI2">
20 members of an ensemble run are divided into different clusters which means groups with similar members according to the hierarchical "Ward method"
The average surface pressure of all members in each cluster are computed and shown as isobares.
The number of members in each cluster determines the probability of the forecast (see percentage)

  <div class="eI1">Dendrogramme:</div>
  <div class="eI2">
A dendrogram shows the multidimensional distances between objects in a tree-like structure.  Objects that are closest in a multidimensional data space are connected by a horizontal line forming a cluster. The distance between a given pair of objects (or clusters) are indicated by the height of the horizontal line.
[http://www.statistics4u.info/fundstat_germ/cc_dendrograms]. The greater the distance the bigger the differences.

  <div class="eI2"><a href="http://www.cnrm.meteo.fr/spip.php" target="_blank">Arome</a> <br>
The Arome forecasting system is a blend of the best components from the M&eacute;so-NH model, the Aladin model, and the IFS/Arpège data assimilation software. Its focus is on the numerical prediction of intense convective systems over mainland France by 2008. Other important weather phenomena will also begin to be reliably forecast, thanks to a high (kilometric) spatial resolution and the use of regional observing systems. The Arome software is designed to be accessible to a wide research community.</br>

  <div class="eI2">La pr&eacute;vision num&eacute;rique du temps (PNT) est une application de la m&eacute;t&eacute;orologie et de l'informatique. Elle repose sur le choix d'&eacute;quations math&eacute;matiques offrant une proche approximation du comportement de l'atmosph&egrave;re r&eacute;elle. Ces &eacute;quations sont ensuite r&eacute;solues, &agrave; l'aide d'un ordinateur, pour obtenir une simulation acc&eacute;l&eacute;r&eacute;e des &eacute;tats futurs de l'atmosph&egrave;re.
