  1. Temperature Inversions the cause of the smoggy brown haze.

  2. REVIEW of CONVECTION The sun’s thermal energy heats up the Earth surface. Warm air has more energy, causing the molecules to excite and spread out (expansion). The expansion of warm air makes it less dense then colder air, which causes it to rise (dense, cold air sinks while less dense, hot air rises). This movement of energy is an example of CONVECTION. (It is what makes the wind blow!) The temperature of the air naturally decreases as it gets further away from the surface of the Earth. --Atmospheric Convection--

  3. What is the normal atmosphere like? Colder air is found higher in the atmosphere. Warm air is found lower in the atmosphere, and grows colder as altitude increases.

  4. Basic Definition for Temperature Inversion A temperature Inversion is a weather condition where the temperature of the air increases as it gets further away from the surface of the Earth. This is the opposite of a normal weather condition.

  5. What is the difference between normal atmosphere conditions and temperature inversion? When a temperature inversion occurs, the warmer air coming from the Earth’s surface slows or stops while the cooler air stays below (capping). (It happens when the Earth’s surface no longer radiates heat.) Normal Warm Air Cool Air

  6. Surface Temp Inversions

  7. Causes of Temperature Inversion

  8. Effects of Temperature Inversion Effects of temperature inversion include decreased air quality, fewer thunderstorms, lower temperatures, and flattened cloud appearance. Examples

  9. How does temperature inversion influence air quality? As pollutants from vehicles, fireplaces, and industry are emitted into the air, the inversion traps these pollutants near the ground, leading to poor air quality.
