1
Q
Adiabatic
A
means occurring without a loss or gain of heat.
2
Q
Diabatic
A
means occurring with an exchange of heat.
3
Q
dry adiabatic rate (DAR)
A
The average DAR is 10°C/1000m
4
Q
Cloud formation process
A
Adiabatic cooling by vertical lift
Air parcel cools to the dew-point temperature.
Air parcel becomes saturated.
Condensation occurs.
5
Q
Relative humidity
A
The ratio of the amount of water vapour actually in the air to the maximum amount possible at a given temperature.
6
Q
Dew-point
A
The temperature at which air achieves saturation
