Study Notes
Temperature and Atmospheric Layers
- The temperature of the tropopause is significantly colder than at Earth's surface.
- The troposphere is the atmospheric layer with the most mixing and overturning of air.
- Air molecules are retained near Earth due to gravity.
Ozone and Atmospheric Composition
- Ozone in the stratosphere absorbs harmful ultraviolet radiation.
- Water vapor typically occupies less than 4% of the air's volume near Earth's surface.
- Near Earth's surface, the air is denser due to a higher concentration of air molecules.
Wind and Atmospheric Pressure
- Wind direction indicates the direction from which the wind is blowing, not where it is going.
- Atmospheric pressure consistently decreases with altitude.
Variable Gases and Weather
- Water vapor is classified as a variable gas in Earth's atmosphere.
- Almost all weather on Earth occurs in the troposphere.
Temperature Profiles and Lapse Rate
- The lapse rate defines the rate of temperature decrease with increasing altitude.
- At night, in cold and dry conditions, atmospheric pressure decreases with altitude.
Composition of Air
- In air at Earth’s surface, nitrogen comprises about 78% and oxygen about 21%.
- Water is the only substance that exists naturally as a solid, liquid, and gas in the current atmosphere.
Atmospheric Layers and Heat Transfer
- The troposphere is the atmospheric layer where humans reside.
- Advection refers to the horizontal transport of atmospheric properties by wind.
- The latent heat of condensation is the heat energy released when water vapor converts to liquid.
Greenhouse Effect
- The atmospheric greenhouse effect results mainly from the absorption and re-emission of infrared radiation by the atmosphere.
