La réduction de la modélisation classique du tenseur des corrélations pression-déformation à la détermination de cinq scalaires dans une base réduite est étudiée. Grâce à cette base réduite, les contraintes de réalisabilité et de géostrophie sont facilement obtenues et un modèle réalisable, consistant avec la théorie de distorsion rapide, est obtenu.
The pressure-strain correlation tensor can be specified by means of five scalar functions in a reduced basis. In this basis, realisability and geostrophic constraints can be easily obtained, and the resulting realisable model is consistent with rapid distorsion theory.
