Quick help: This height estimates the cloudbase for small cumulus in the BL only at locations (coloured areas on BLIPMAP charts) where this cumulus formation is probable. Where these small clouds are not probable the areas remain grey. Nevertheless cumulus can sometimes even occur on grey areas over a small-scale ridge not resolved by the model's smoothed topography. If there is a forecast probable BL overcast, you should expect the cloud base (much) lower than predicted here. The lower chart shows the base height of BL clouds (coloured areas) and the BL clouds cover pct (black dash and solid lines).
Aide rapide: Il s'agit ici de prvoir la base des petits cumulus dans la couche convective (CC). La couleur correspond l'altitude de la base. Si une ou l'autre plage du domaine reste grise, les petits cumulus y sont peu probables mais pas impossibles. S'il y a surdveloppement nuageux dans la CC, la base des nuages sera plus basse que prvue ici !!! La carte du bas montre la mme chose mais en plus le degr en % de la couverture nuageuse de la CC (lignes noires continues et discontinues).
