Lapse rates Flashcards
1
Q
What is environmental lapse rate?
A
Rate at which the air cools is about 6.5degrees every 1000meters
2
Q
What happens to temps as altitude increases?
A
As altitude increases because of gravity, the air closer to sea level has more particles in it. At higher altitudes there are less particles
3
Q
What is adiabatic cooling?
A
At higher altitudes the pressure on the parcel of air is less, so the parcel of air can expand. As the air expands the heat in the particles has to heat a bigger area
4
Q
What is DALR (dry adiabatic lapse rate) ?
A
A parcel of air that is not 100% relative humidity, it will cool at 9.8degrees per 1000meters.
5
Q
What is SALR (saturated adiabatic lapse rate)
A
If parcel of air that have reached relative humidity, it will cool at 5.5degrees
