Tout d\u2019abord, les vents ne soufflent pas de la m\u00eame mani\u00e8re selon l\u2019altitude. Ensuite, il faut pouvoir mesurer leur force, leur vitesse et leur direction. Enfin, il est important de voir comment la force du vent peut varier en journ\u00e9e. Les outils de mesure doivent aussi pouvoir fournir des donn\u00e9es concernant l\u2019humidit\u00e9 et la pression atmosph\u00e9rique qui influencent la production \u00e9olienne.<\/p><p>Chaque site pr\u00e9sente des caract\u00e9ristiques diff\u00e9rentes.
