If the environmental lapse rate is 5oC per 1000 m and the temperature at the earth's surface is 25oC, then the air temperature at 2000 m above the ground is?
30oC
20oC
15oC
none of these
If an air parcel is given a small push upward and it falls back to its original position, the atmosphere is said to be?
Stable
Unstable
Adiabatic
Isothermal
None of these
A rising parcel of air that does not exchange heat with its surroundings is referred to as?
Adiabatic
Isothermal
Advection
Forced lifting
Knowledge of air stability is important because:
It determines the direction of movement of storms
It determines the vertical motion of air
It determines the vertical motion of air
It determines the movement of high-pressure areas
The difference between the "moist" and "dry" adiabatic rates is due to:
The fact that saturated air is always unstable
the fact that an unsaturated air parcel expands more rapidly than a saturated air parcel
the fact that moist air weighs less than dry air
the fact that latent heat is released by a rising parcel of saturated air
