What measurement can be used to determine the stability of the atmosphere?
Actual lapse rate.
How does the moist adiabatic lapse rate compare with the dry-adiabatic lapse rate?
environmental lapse rate involves the actual temperature of the atmosphere at various heights. adiabatic cooling is the cooling of air caused when air is not allowed to expand or compress.
When the environmental lapse rate is between the dry and moist adiabatic lapse rates conditions are described as what?
When the environmental lapse rate is between the dry and moist adiabatic lapse rates, conditions are described as conditionally unstable. This means that the atmosphere is stable when unsaturated and unstable when saturated, indicating the potential for convective storms to develop under the right conditions.
The rising and subsequent cooling of air at the rate of 10C per 1000 meters is called?
This process is known as the environmental lapse rate, which describes how air temperature changes with altitude in the Earth's atmosphere. A decrease of 1 degree Celsius per 100 meters in altitude is a standard approximation for the environmental lapse rate.
The rate at which temperature decreases with increasing altitude is known as?
The rate at which temperature decreases with increasing altitude is known as the lapse rate.
What environmental lapse rate does stability prevail?
less than the wet adiabotic rate
What must the environmental lapse be in order for stability to prevail?
less than the wet adiabatic rate.
What is the difference between the normal lapse rate and the environmental lapse rate?
The environmental lapse rate (ELR), is the rate of decrease of temperature with altitude in the stationary atmosphere at a given time and location.While Normal Lapse Rate is average concept for temperature decline with height in the troposphere.
What measurement can be used to determine the stability of the atmosphere?
Actual lapse rate.

What is the actual decrease in temperature with an increase in altitude through the tropospher?
Environmental lapse rate
Why is saturated adiabatic lapse rate a lesser than dry adiabatic lapse rate?
The saturated adiabatic lapse rate is lower than the dry adiabatic lapse rate because during the process of condensation, heat is released into the atmosphere, which partially offsets the cooling effect of rising air. This release of heat makes the cooling rate of saturated air less than that of dry air as it ascends through the atmosphere.

When the environmental lapse rate is less than the dry adiabatic rate a parcel of air will be?
Then the air is called "stable" because a parcel of air from the surface lifted upward will drop in temperature at the dry adiabatic lapse rate. If the environmental lapse rate is less, then the lifted air will be cooler and more dense than the surrounding air, and thus stop moving upward through the atmosphere.
What is saturated adiabatic lapse rate?
The Saturated adiabatic lapse rate is :All air has a moisture content and when a parcel of air heated by its surroundings starts to rise at the dry adiabatic lapse rate it rises until its temperature reaches that of the dew point where its vapour content starts to condense out as tiny liquid water droplets and normally forms the base of a cloud. As this 'heated' parcel of air is still warmer than the environmental lapse rate (circa 1C/1000ft) latent heat is being released as it still continues to rise but now at a reduced rate - it is this reduced rate @1.5C/1000ft that is known as the saturated adiabatic lapse rate. It will cease rising when the environmental temperatures level out and this forms or terminates resulting as the top of the cloud. Meteorologists and pilots use this environmental lapse rate and known dew point temperature to work out the base and tops of cloud for regional and airport forecasts.
1 degree c of cooling per 160 meters of altitude?
occurs in the tropopause- environmental lapse rate or normal elapse rate ELR
