We study shallow moist Rayleigh–Bénard convection in the Boussinesq approximation in three-dimensional direct numerical simulations. The thermodynamics of phase changes is approximated by a piecewise linear equation of state close to the phase boundary. The impact of phase changes on the turbulent fluctuations and the transfer of buoyancy through the layer is discussed as a function of the Rayl...

The coexistence of several schools in non-equilibrium thermodynamics is a reality.At the beginning of the 21st century, the thermodynamics of systems far from. However, it turns out that many nonequilibrium phenomena can be described.An alternate evolutionary hypothesis is discussed: non-equilibrium. Literature on non-equilibrium thermodynamics and its relationship to evolutionary.The online ve...

The word “derecho” is used to differentiate a storm having straight‐line winds as opposed to rotational, tornadic winds. Although the term “derecho” is relatively old, derechos were not readily recognized by the general public until recent outbreaks caused significant widespread damage and associated fatalities. Most notably, the 2012 Mid‐Atlantic Derecho in the USA brought these types of storm...

[1] A combination of cloud-top and columnar droplet sizes derived from the multi Tropical Rainfall Measurement Mission (TRMM) sensors reveals the sensitivity of the aerosols effect on cloud-precipitation processes due to environmental vertical thermodynamic structure. First, the magnitude of aerosol indirect effect could be larger with the analysis of columnar droplet sizes than that derived fr...

Greenland ice sheet mass loss has accelerated in the past decade responding to combined glacier discharge and surface melt water runoff increases. During summer, absorbed solar energy, modulated at the surface primarily by albedo, is the dominant factor governing surface melt variability in the ablation area. Using satellite-derived surface albedo with calibrated regional climate modeled surfac...

Some features of hydro-and thermodynamics, as applied to atmospheres and to stellar structures, are puzzling: 1. It is not understood or universally agreed whether an isolated gas, in an external gravitational field, tends spontaneously to a final state in which the temperature is uniform. 2. Arguments in which a concept of energy plays a role, in the context of hydro-thermodynamical systems an...

The birth, raise, development and fortunes of a fundamental theory in thermodynamics, the axiomatic thermodynamics, a creation of Constantin Carathéodory, is thoroughly presented together with a summary of Carathéodory’s biography. Axiomatic thermodynamics is centered around some interesting properties of Pfaffian differential equations, which are here introduced and used for some well-known ca...

isotherm equation is one of the important scientific bases for adsorbent selection. there are different isotherms that do not account for an adsorbate, different chemisorption geometries on the nanoporous surface. it is interesting to introduce a general isotherm, which considers different chemisorption geometries of an adsorbate on nanoporous surfaces. in this study, an isotherm for non-dissoci...

The concept of entropy and its relevant principles, mainly the principle of maximum entropy production (MEP), the effect of negative entropy flow (NEF) on the organization of atmospheric systems and the principle of the Second Law of thermodynamics, as well as their applications to atmospheric sciences, are reviewed. Some formulations of sub-grid processes such as diffusion parameterization sch...

The investigation of the coupled atmosphere-ocean system is not only scientifically challenging but also practically important. We consider a coupled atmosphere-ocean model, which involves hydrodynamics, thermodynamics, and random atmospheric dynamics due to short time influences at the air–sea interface. We reformulate this model as a random dynamical system. First, we have shown that the asym...
