Chapter 5 Flashcards
Orographic uplift
forced uplifting on a topographic barrier
windward side
Side the wind hits the topographic barrier
leeward side
Side the wind does not hit on a topographic barrier
Orographic clouds
formed through orographic uplift
rain shadows
arid condition on leeward mountain sides
lenticular cloud
lens shaped wave clouds
rotor cloud
visible rising swirling air
adiabatic cooling
no interchange of heat with its outside surroundings(temp changes as a result of expanding/contracting)
stable air
air is staying in the same place or sinking because its colder than its surrounding
unstable air
air rises on its own because its warmer than its surroundings
adiabatic lapse rate(dry rate)
10 degrees C/1000m
adiabatic lapse rate(wet rate)
6 degrees C/ 1000m
Environmental Lapse rate
the lapse rate outside of the air parcel
absolute stability
the environmental lapse rate is less than both adiabatic lapse rates
Unstable atmosphere
environmental lapse rate is more than both adiabatic lapse rates
