The atmosphere is divided into 4 distinct layers |
Troposphere, stratosphere, mesosphere and thermosphere |
|
|
Energy in the atmosphere |
The electromagnetic spectrum consists of waves of varying lengths including visible light. When insolation comes in contact with materials in Earth's surface sometimes the radiation is absorbed, sometimes is reflected, and sometimes the radiation passes right through. |
|
|
Energy in the atmosphere |
The three types of wavelength that are greatest concern to most humans are visible light, infrared, and ultraviolet |
|
|
Visible light |
Most visible light insolation reaches Earth's surface except on cloudy days when atmospheric transparency is decreased or when albedo is high |
|
|
Visible light |
A smooth, light colored surface will reflect light best. A dark, crinkly surface will absorb light the best |
|
|
Ozone |
It is found in the stratosphere is the principal compound responsible for absorbing ultraviolet radiation from the sun |
|
|
Conduction |
The process by which heat energy is transmitted through collisions between neighboring atoms or molecules |
|
|
Convection |
The transfer of heat by circulating it through air or liquids |
|
|
Radiation |
The movement of energy through empty space in the form of electromagnetic waves |
|
|
Thermometer |
An instrument that measures temperature |
|
|
Psychrometer |
An instrument for determining atmospheric humidity by the reading of 2 thermometers |
|
|
Barometer |
Instrument used to measure atmospheric pressure |
|
|
Anemometer |
Instrument that measures wind speed and wind pressure |
|
|
Wind vane |
Used for indicating wind direction |
|
|
Wet bulb |
The temperature of adiabatic saturation |
|
|
Air temperature |
A measure of how hot or cold the air is |
|
|
Dew point |
The temperature at which the atmosphere is saturated with water vapour |
|
|
Relative humidity |
The amount of water vapor actually in the air |
|
|
Weather station models |
The closer the dew point is to the air temperature, the greater the chance of condensation and therefore precipitation |
|
|
Evaporation |
The process by which water changes from a liquid to a gas or vapor |
|
|
Transpiration |
The process of water movement through a plant and it's evaporation from aerial parts |
|
|
Condensation |
The process by which water vapor in the air is changed into liquid water |
