Atmosphericthermodynamics is the study of heat to work transformations and the reverse in the earth s atmospheric system in relation to weather or climate . Following the fundamental laws of classical thermodynamics , atmosphericthermodynamics studies such phenomena as properties of moist air, formation of clouds, atmospheric convection, boundary layer meteorology, and vertical stabilities in the atmosphere. Atmospheric thermodynamic diagrams are used as tools in the forecasting of storm development.

thermodynamics cTopic Branches Equilibrium Thermodynamics is the systematic study of transformations of matter and energy in systems as they approach equilibrium. The word equilibrium implies a state of balance. Equilibrium thermodynamics, in origins, derives from analysis of the Carnot cycle . Here, typically a system, as cylinder of gas, is set out of balance via heat input from a combustion combustion reaction . Then, through a series of steps, as the system settles into its final equilibrium state, work is extracted. In an equilibrium state there are no unbalanced thermodynamic potential potentials , or driving forces, within the system. A central aim in equilibrium thermodynamics is given a system in a well defined initial state thermodynamic state , subject to accurately specified constraints, to calculate what the state of the system will be once it has reached equilibrium. An equilibrium state is obtained by seeking the extrema of a thermodynamic potential function, whose nature depends on the constraints imposed on the system. For example, a chemical reaction at constant temperature ... of their entropy . Equilibrium thermodynamics differs from non equilibrium thermodynamics , in that, with the latter ... by dissipative thermodynamic fluxes.

The specific volume , an intensive property , is the system s volume per unit of mass. Volume is a function of state and is interdependent with other thermodynamic properties such as pressure and thermodynamic temperature temperature . For example, volume is related to the pressure and thermodynamic temperature temperature of an ideal gas by the ideal gas law . The physical volume of a system may or may not coincide with a control volume used to analyze the system. Overview The volume of a thermodynamic system typically refers to the volume of the working fluid, such as, for example, the fluid within a piston. Changes to this volume may be made through an application of work thermodynamics work , or may be used to produce work. An isochoric process however operates at a constant volume, thus no work can be produced. Many other thermodynamic process es will result in a change in volume. A polytropic process , in particular, causes changes to the system so that the quantity math pV n math is constant where math p math is pressure, math V math is volume, and math n math is the polytropic index , a constant . Note that for specific polytropic indexes a polytropic process will be equivalent to a constant property process. For instance ... in the form of work is involved.

orphan date August 2010 The thermodynamics of the universe is dictated by which form of energy dominates it relativistic particle s which are referred to as radiation , or non relativistic particles which are referred to as matter. The former are particles whose rest mass is zero or negligible compared to their energy, and therefore move at the speed of light or very close to it The latter are particles whose kinetic energy is much lower than their rest mass and therefore move much slower than the speed of light. The intermediate case is not treated well analytic solution analytically .

Such measurements are performed in a variety of ways including remote sensing and in situ Earth and atmospheric sciences in situ observations. The most common in situ sounding is a radiosonde , which usually is a weather balloon , but can also be a rocketsonde . Remote sensing soundings generally use passive infrared and microwave radiometer s airborne instruments surface stations Earth observing satellite instruments such as Atmospheric Infrared Sounder AIRS and Advanced Microwave Sounding Unit AMSU There is even a sounder at Mars the Mars climate sounder on the Mars Reconnaissance Orbiter Direct methods Sensors that measure atmospheric constituents directly such as thermometers, barometers and humidity sensors can be sent aloft on balloons, rockets or dropsonde s. They can also be carried on the outer hulls of ships and aircraft or even mounted on towers. In this case, all that is needed to capture the measurements are storage devices and or transponder s. Indirect methods The more challenging case involves sensors, primarily satellite mounted, such as radiometers , optical sensors, RADAR , LIDAR and similar light based instruments as well as sonar since these cannot measure the quantity of interest, such as temperature, pressure, humidity etc, directly.
