What happens to an air parcel if it ascends or descends in the atmosphere?
Give this one a try later!
If it ascends, it expands due to decreased pressure (adiabatic cooling), if it
descends it compresses due to increased pressure (adiabatic heating)
Sublimation
Give this one a try later!
Heat is absorbed to change a solid to gas
Radiation
, Give this one a try later!
Air temp drops to dewpoint, clear nights with light winds
Cumuli form clouds
Give this one a try later!
Cottony, internal structure of updrafts and downdrafts, indicate instability,
precipitation is showery
Cirri form clouds
Give this one a try later!
Wispy clouds, feather like, made of ice crystals, form the anvil on a
thunderstorm
Negative Buoyant
Give this one a try later!
If colder (heavier) than surrounding air, it will continue downward
What is lapse rate?
