A moist "available enthalpy" norm: definition and comparison with existing "energy" norms

Atmospheric and Oceanic Physics 2015-10-21 v2 Fluid Dynamics Geophysics

Abstract

Moist-air norms and inner-products are currently used in atmospheric science for computing dry or moist singular vectors and for determining forecast errors or sensitivity to observations based on tangent linear and adjoint models. A new moist-air norm is defined starting from old results published in Marquet (QJRMS 1993) and based on the "Available Enthalpy" approach, namely one of the Exergy function defined in general thermodynamics. Some interesting and promising impacts of this new "Available Enthalpy" norm are described in this brief version of a paper to be submitted to the QJRMS.
