Inversion Layer

AnalysisInversion Layer



If air what contains moisture in troposphereAtmosphere which is from land surface to tropopause.
It is located beneath stratosphere.
We could watch weather phenomenon as exemplified by,
high and low pressure and flux and reflux of cloud.
moved to up in the air,

it have a behavior decrease in temperature about 6.5℃/km,

this behavior called indifferent state.For real air, by time or place,

its temperature's distribution is not lower as it up in the air, contrary, its temperature get up.

Like this phenomenon is called temperature's reverse,the reversing formation is inversion layer.


Its matter are,

・At windy fine night,air of the atmosphere near the earth's surface gotten cool by radiative cooling

Subsidence inversion, temperature is raised by airy air mass Huge agglomerate which have horizontally-averaged equable.
It come into being when atmosphere become diminished in widespread area.
It can divide into continental air mass and maritime air mass
and can subdivide into the Ogasawara air mass and the Okhotsk Sea air mass.
settles down and increases

 in temperature with getting air which is blasting out in the anticyclone.

In condition that inversion layer is making, Temperature will decrease

at a rate of about 6.5 ℃ / km air mass if the rising convection takes place,

but, doing so it will cooler(heavier) than circumjacent air, down as before.

And,in other hand,if air mass downed,boost as before height.

For that reason,air in inversion layer is difficult to mix,

air pollutant accumulated and high concentrations of pollution-prone.


It is likely to be formed over the evening, at night, early morning of autumn and winter.
