Pour les applications opérationnelles il paraît illusoire de chercher à définir un critère numérique unique ayant une signification universelle. Par contre, si l’on se limite aux incidences des circonstances atmosphériques sur une catégorie particulière d’activités humaines, il est possible de combiner certains éléments climatiques de façon significative. Sur le plan agricole on peut citer, par exemple : - l’indice héliothermique de Geslin [...] - l’évapotranspiration potentielle [...] - le bilan potentiel ou déficit théorique, [...] Ce critère peut servir d’indicateur du déficit d’approvisionnement en eau de la végétation. 2, record 2, French, - d%C3%A9ficit%20th%C3%A9orique

Application optique dans un domaine inattendu, la navigation inertielle, le gyrolaser est un nouveau gyromètre plus fiable que son prédécesseur mécanique, et particulièrement bien adapté aux conditions d’utilisation plus dures de l'avionique militaire et spatiale. [...] Principe. Effet Sagnac. L'interféromètre de Sagnac met en jeu, sur un trajet optique fermé, deux rayons lumineux se propageant en sens contraire. La rotation du bloc optique ainsi constitué introduit alors une différence de phase. Les calculs font appel à la relativité générale, et prouvent que le calcul classique est une bonne approximation. On montre ainsi que l'écart temporel DT est proportionnel à la vitesse de rotation W.
