Met Thermodynamics Flashcards
1
Q
Is dew point higher over ice or water?
A
Ice
2
Q
Relative humidity relationship with temperature
A
Increases with decreasing temperature whilst keeping a constant vapour pressure
3
Q
What is an isothermal layer
A
A vertical extent of air that does not have decreasing temperature with height
4
Q
How do you make an isothermal layer
A
ELR must be less than zero and thus less than SALR
5
Q
When is an air mass stable
A
When ELR is less than 1.8c/1000ft
6
Q
What is an unsaturated air mass
A
1°C/100m
