Term
|
Definition
|
|
Term
|
Definition
Indicates how close air is to saturation rather than actual quantity of water vapor in air |
|
|
Term
Relative Humidity Calculation |
|
Definition
(Actual H20 vapor in air / max H20 vapor possible in air at that temp) X 100 |
|
|
Term
|
Definition
Temperature air is cooled to reach saturation, measure of moisture content |
|
|
Term
|
Definition
Two identical thermometers, One dry measures air temp, one wet measures dryness larger the difference in temps between wet & dry, the lower the humidity |
|
|
Term
|
Definition
Radiation cooling of ground and air, slight breeze needed |
|
|
Term
|
Definition
Warm, moist air blowing over cold surface, 10-30 kph winds |
|
|
Term
|
Definition
Humid air moves up a sloping land form/mountain, air expands then and cools adiabatically |
|
|
Term
|
Definition
Cool air moves over warm water, moisture evaporates and saturates the air |
|
|
Term
|
Definition
Moisture in air condenses on surface already below freezing, Ice crystals form |
|
|
Term
|
Definition
Temp drops below dew point, Continues to drop below freezing, Ice forms |
|
|
Term

|
|
Term
What does expanding air do? |
|
Definition
|
|
Term
What does compressed air do? |
|
Definition
|
|
Term
|
Definition
Air ascends above lifting condensation level, 5°C/1000m or 3.3°F/1000ft |
|
|
Term
|
Definition
Unsaturated air cools at rate 10°C/1000m or 5.5°F/1000ft |
|
|
Term
LCL (Lifting Condensation Level) |
|
Definition
Condensation is triggered when air rises to its saturation point, Clouds forms |
|
|
Term
|
Definition
Occurs when elevated terrains act as barriers to flow of air |
|
|
Term
|
Definition
Masses of warm & cold air collide producing fronts |
|
|
Term
|
Definition
Horizontal air flow results in upward movement |
|
|
Term
Localized Convective Lifting |
|
Definition
Unequal surface heating causes localized pockets of air to rise |
|
|
Term
|
Definition
Resists vertical movement |
|

|
Term
Environmental Lapse Rate (ELR) |
|
Definition
Actual temp of atmosphere |
|
|
Term
|
Definition
State of air in atmosphere when its lapse rate of temp is less than saturation-adiabatic lapse rate |
|
|
Term
|
Definition
State of air in atmosphere when it's superadiabatic lapse rate of temperature is greater than dry-adiabatic lapse rate |
|
|
Term
|
Definition
Moist air has an environmental lapse rate between dry and wet adiabatic rates |
|
|
