A reference atmospheric model describe how the ideal gas properties namely: pressure, temperature, density, and molecular weight of an atmosphere change, primarily as a function of altitudeand sometimes also as a function of latitudeday of yearetc. A static atmospheric model has a more limited domain, M.E.H.R.

- Atmospheric Conditions time. A standard atmosphere is defined by the World Meteorological Organization as M.E.H.R.

- Atmospheric Conditions hypothetical vertical distribution of atmospheric temperature, pressure and density which, by international agreement, is roughly representative of year-round, midlatitude conditions. Typical usages are as a basis for Cats Whiskers - Lou Monte - Five Classic Albums Plus Singles altimeter calibrations, aircraft performance calculations, aircraft and rocket design, ballistic tables, and M.E.H.R.

- Atmospheric Conditions diagrams. For example, the U. Standard Atmosphere derives the values for air temperature, pressure, and mass density, as a function M.E.H.R. - Atmospheric Conditions altitude above sea level. The gas which comprises an atmosphere is usually assumed to be an ideal gaswhich is to say:. The gas is held in place by so-called " hydrostatic " forces. That is to say, for a particular layer of gas at some altitude: the downward towards the planet force of its weight, the downward force exerted by pressure in the layer above it, and the upward force exerted by pressure in the layer below, Spacecraft - Radical Distortion - Psychedelic Dreams sum to zero.

Mathematically this is:. Finally, these variables describing the system do M.E.H.R. - Atmospheric Conditions change with time; i. For the basis of simplicity it doesn't vary with latitude, altitude or location. More complex models, account for this variations.

If the density of a gas is persistent, then it isn't really behaving like a gas. Instead it is behaving like an incompressible fluidor liquidand this situation looks more like an ocean. Assuming density is constant, then a graph of pressure vs altitude will have a retained slope, since the M.E.H.R. - Atmospheric Conditions of the ocean over head is directly proportional to its depth. This atmospheric model assumes both molecular weight and temperature are constant over a wide range of altitude.

Such a model may be called isothermal constant temperature. Inserting constant molecular weight and constant temperature into the equation for the ideal gas law produces the result that density and pressure, the two remaining variables, depend only on Hinter Den Kulissen Von Paris - Unknown Artist - 28 Top-Hits À Gogo other.

For this reason, this model may also be called barotropic density depends only on pressure. For the isothermal-barotropic model, density and pressure turn out to be exponential functions of altitude. The total air mass below a certain altitude is calculated by integrating over the density function.

For the ocean example there was a sharp transition in density at the top or "surface" of the ocean. However, for atmospheres made of gas there is no equivalent sharp transition or edge. Gas atmospheres simply get less and less dense until they're so thin that they're space. The U. Standard Atmosphere model starts with many of the same assumptions as the isothermal-barotropic model, including ideal gas behavior, and constant molecular weight, but it differs by defining a more realistic temperature function, consisting of eight Haunts Of Evil Spirit - Mad Professor - Dub Me Crazy 6: Schizophrenic Dub points connected by straight lines; i.

See graph. Of course the real atmosphere does not have a temperature distribution with this exact shape. The temperature Something For Liza - The Vince Guaraldi - Conte Candoli Quartet - The Vince Guaraldi - Conte Candoli is an approximation.

Values for pressure and density are then calculated based on this temperature function, M.E.H.R. - Atmospheric Conditions the constant temperature gradients help to make some of the maths easier. The NASA Earth Global Reference Atmospheric Model Earth-GRAM was developed by the Marshall Space Flight Center to provide a design reference atmosphere that, unlike the standard atmospheres, allows for geographical variability, a wide range of altitudes surface to orbital altitudesand different months and times of day.

It can also simulate spatial and temporal perturbations in atmospheric parameters due to turbulence and other atmospheric perturbation phenomena. It is available [2] in computer code written in Fortran.

Gravitational acceleration, g zdecreases with altitude since moving up means moving away from the planet's center. This problem of decreasing g can be dealt with by defining a transformation from real geometric altitude z M.E.H.R. - Atmospheric Conditions an abstraction called "geopotential altitude" hdefined:. Which basically says the amount of work done lifting a test mass m to height z through an atmosphere where gravity decreases with altitude, is the same as the amount of work done lifting that same mass to a height h through an atmosphere where g magically remains equal to g0its value at sea level.

This geopotential altitude h is then used instead of geometric altitude z in the hydrostatic equations. From Wikipedia, the free encyclopedia. Redirected from Static atmospheric models.
