    EnglishThe concept of available potential energy has been developed in meteorolgy by E- N- Lorenz in order to understand how the incoming solar energy is transformed within the atmosphere and why the observed values of kinetic energy of wind are much smaller than might be expected. Lorenz has succeeded in explaining, on a global scale, the energy cycle associated with the general circulation of the atmosphere. This paper presents the history of other theories of the conversion of energy that have been introduced by the founders of thermodynamics. It is shown that one of them, the available enthalpy approach, can be applied to meteorology. A local available enthalpy cycle is derived to investigate the conversions that take place within a limited area of the atmospheric domain. francaisLa notion d'energie potentielle utilisable a ete developpee en meteorologie par E. N. Lorenz afin de comprendre comment l'energie solaire incidente est transformee dans l'atmosphere et pourquoi les valeurs observees de l'energie cinetique du vent sont tres inferieures a ce que l'on pourrait attendre. Lorenz a reussi a expliquer, a l'echelle planetaire, le cycle energetique associe a la circulation generale de l'atmosphere. Cet article presente l'histoire d'autres conceptions de la disponibilite de l'energie, introduites par les fondateurs de la thermodynamique. On montre que l'une d'entre elles, la notion d'enthalpie utilisable, peut etre appliquee a la meteorologie. On etablit un cycle local d'enthalpie utilisable qui permet d'etudier les conversions d'energie qui se produisent dans un domaine limite de l'atmosphere.

    La mission Megha-Tropiques récolte des observations du cycle de l’eau et de l’énergie dans l’atmosphère intertropicale depuis 2011. L’utilisation de ces observations a démontré la pertinence de son orbite originale inclinée sur l’équateur, tant pour l’estimation des précipitations que pour la prévision numérique du temps. L’exploitation scientifique, toujours en cours, autour de l’étude des relations entre la vapeur d’eau et les nuages, le cycle de vie des systèmes convectifs tropicaux et l’hydrométéorologie a permis plusieurs avancées brièvement présentées ici. De nombreux centres opérationnels à travers le monde assimilent les données de la mission, disponibles en temps réel, grâce aux récents progrès de l’interprétation de la mesure à 183 GHz. The Megha-Tropiques mission has been collecting observations of the water and energy cycle in the intertropical atmosphere since 2011. The use of these observations has demonstrated the relevance of its original orbit inclined over the Equator both for the precipitation estimates and for numerical weather prediction. The ongoing scientific exploration of the relationship between water vapor and clouds, the life cycle of tropical convective systems, and hydrometeorology has led to many advances that are briefly presented here. Many operational centres around the world are assimilating available mission data in real time thanks to recent advances in the interpretation of the 183 GHz measurement. International audience
