humidity Flashcards
1
Q
what is humidity?
A
the amount of water vapour in the air
2
Q
saturation of air with water vapour depends on what?
A
temperature
3
Q
what is relative humidity?
A
our body’s main source of cooling is evaporation of perspiration, the more moisture there is in the air, the less evaporation takes place and the warmer we feel
4
Q
what is the dew point?
A
-temp at which a parcel air reaches saturation
-cooling air below its dew point temp typically generates dew, fog or clouds when the dew point is above freezing and frost when it is below freezing
5
Q
what is the condensation level?
A
level where air parcel rises enough that it cools to its dew point, triggering condensation
