TemperatureInversions



Air molecules l.jpg
Air Molecules

  • As you go higher in the atmosphere, air becomes less dense.

  • The air molecules are spaced further apart 1



Air density l.jpg
Air Density

  • That is why it is hard to breathe at high altitudes.

  • That is also why it is colder at high altitudes


Molecule density verses temperature l.jpg
Molecule Density Verses Temperature

Heat is from molecule collisions.

Fewer molecules……

Fewer collisions……

Less heat! 2


Why air density changes l.jpg
Why Air Density Changes

  • The weight of the air causes the at the ground to have high pressure.

  • Gravity pulls the air close to the earth

  • The high pressure pushes the air molecules close together 3



Temperature vs pressure l.jpg
Temperature vs Pressure

  • As the pressure of a gas drops, it’s temperature also drops.

  • Evidence

    • Condensation on a Coleman lantern

    • Warm soda cools when you open it.


Air temperature vs altitude l.jpg
Air Temperature vs Altitude

SO,

The higher you go. . .

The less dense the air . . .

The colder it gets!






Temperature inversion15 l.jpg
Temperature Inversion rises?

  • A temperature inversion is when a layer of warmer air covers the colder air at ground level.

    6


Temperature inversion16 l.jpg
Temperature Inversion rises?

  • It forms when the ground level air is kept cold by the cold ground.

  • Then a warm air mass comes from another area and covers the cold air.

  • The inversion acts like a lid over the cold ground level air 7-8






The air gets dirty l.jpg
The Air Gets rises? Dirty!


Real dirty l.jpg
Real rises? Dirty!



So what l.jpg
SO WHAT? rises?

  • How do

  • temperature inversions

  • affect us?


What can we do l.jpg
What Can We Do? rises?

What are some ways

we can protect ourselves

from the effects of

temperature inversions?
