A summary of several meteorological properties of the moist-air entropy variables and
Pascal Marquet
The aim of this note is to describe several meteorological properties shown in a conference talk (Marquet, January 2022) for the moist-air specific entropy, the associated potentia…
Towards the use of conservative thermodynamic variables in data assimilation: a case study using ground-based microwave radiometer measurements
Pascal Marquet, Pauline Martinet, Jean-François Mahfouf +2
This study aims at introducing two conservative thermodynamic variables (moist-air entropy potential temperature and total water content) into a one-dimensional variational data as…
On moist potential temperatures and their ability to characterize differences in the properties of air parcels
Pascal Marquet, Bjorn Stevens
A framework is introduced to compare moist `potential' temperatures. The equivalent potential temperature, the liquid water potential temperature, and the entropy…
Application of the second law to the atmosphere: impacts of the third-law definition for the moist-air entropy
Pascal Marquet
Calculations of entropy fluxes and production rate have been evaluated with some success to study atmospheric processes. However, recurring questions arise as to how best to take i…
The third law of thermodynamics or an absolute definition for Entropy. Part 2 : definitions and applications
Pascal Marquet
This paper is the second part of a previous paper (Marquet, 2019) dealing with the need to define the entropy with an absolute way, by using the third law of thermodynamics. In thi…
The third law of thermodynamics or an absolute definition for Entropy. Part 1 : the origin and applications in thermodynamics
Pascal Marquet
This article describes the third law of thermodynamics. This law is often poorly known and is often decried, or even considered optional and irrelevant to describe weather and clim…
Comment on the paper "Generalized dynamic equations related to condensation and freezing processes" by Wang and Huang (2018)
Pascal Marquet
The condensation Probability Function defined in papers of X.R. Wang is criticized on many aspects. The modified latent heat and potential temperature are plotted and compared to u…
The first and second order approximations of the third-law moist-air entropy potential temperature
Pascal Marquet
It is important to be able to calculate the moist-air entropy of the atmosphere with precision. A potential temperature has already been defined from the third law of thermodynamic…
Exergy in meteorology: Definition and properties of moist-air available enthalpy
Pascal Marquet
The exergy of the dry atmosphere can be considered as another aspect of the meteorological theories of available energies. The local and global properties of the dry available enth…
Definition of the moist-air exergy norm: a comparison with existing "moist energy norms"
Pascal Marquet, Jean-François Mahfouf, Daniel Holdaway
This study presents a new formulation for the norms and scalar products used in tangent linear or adjoint models to determine forecast errors and sensitivity to observations and to…
Reply to the Comments of Olivier Pauluis to the paper "A Third-Law Isentropic Analysis of a Simulated Hurricane"
Pascal Marquet, Thibaut Dauhut
A careful reading of old articles puts Olivier Pauluis' criticisms concerning the definition of isentropic processes in terms of a potential temperature closely associated with the…
On consequences of measurements of turbulent Lewis number from observations
Pascal Marquet, William Maurel, Rachel Honnert
Almost all parameterizations of turbulence in NWP models and GCM make the assumption of equality of exchange coefficients for heat and water . However, large uncertainti…
A Third-Law Isentropic Analysis of a Simulated Hurricane
Pascal Marquet
The moist-air entropy can be used to analyze and better understand the general circulation of the atmosphere or convective motions. Isentropic analyses are commonly based on studie…

The mixed-phase version of moist-air entropy
Pascal Marquet
The aim of this note is to derive the mixed-phase version of the moist-air entropy potential temperature derived in Marquet (2011). This mixed-phase version is suitable to de…

Pascal Marquet, Jean-François Geleyn
Internal energy, enthalpy and entropy are the key quantities to study thermodynamic properties of the moist atmosphere, because they correspond to the First (internal energy and en…
Comments on "MSE minus CAPE is the True Conserved Variable for an Adiabatically Lifted Parcel"
Pascal Marquet
In a recent paper, Romps (JAS, vol.72, p.3639-3646, 2015, hereafter R15) argues that the moist-air static energy (MSE) is only approximately conserved for an adiabatically lifted p…

Definition of Total Energy budget equation in terms of moist-air Enthalpy surface flux
Pascal Marquet
Uncertainty exists concerning the proper formulation of surface heat fluxes, namely the sum of "sensible" and "latent" heat fluxes, and in fact concerning these two fluxes if they…
A moist "available enthalpy" norm: definition and comparison with existing "energy" norms
