What is the importance of atmospheric stability?

Atmospheric stability is a measure of the atmosphere’s tendency to discourage or deter vertical motion, and vertical motion is directly correlated to different types of weather systems and their severity.

Which will occur least when the relative humidity is 100 percent?

evaporation

What will happen if a parcel of air is displaced vertically in an unstable environment?

What will happen if a parcel of air is displaced vertically in an unstable environment? It will continue to accelerate away from its original position.

What happens to an air parcel as it rises?

The air parcel expands as it rises and this expansion, or work, causes the temperature of the air parcel to decrease. As the parcel rises, its humidity increases until it reaches 100%. Above this point the cloud droplets grow by condensation in the rising air.

What will happen when the temperature of the air parcel is the same as the air around it?

If the parcel temperature is equal to the surrounding air temperature, the parcel is said to be neutral and would remain stationary if released. When a parcel becomes neutral, it often signals a transition from stable to unstable or unstable to stable.

In which environment is an air parcel most likely to rise?

temperature of an air parcel to the temperature of its environment.  If an air parcel is warmer than its environment it will rise.  If an air parcel is colder than its environment it will sink.

What is the difference between normal lapse rate and adiabatic lapse rate?

Lapse rate, rate of change in temperature observed while moving upward through the Earth’s atmosphere. It differs from the adiabatic lapse rate, which involves temperature changes due to the rising or sinking of an air parcel. Adiabatic lapse rates are usually differentiated as dry or moist.

What is the rate of lapse rate?

The Lapse Rate is the rate at which temperature changes with height in the Atmosphere. Lapse rate nomenclature is inversely related to the change itself: if the lapse rate is positive, the temperature decreases with height; conversely if negative, the temperature increases with height.
