What else can I help you with?
What is the rate of cooling as you increase in elevation?
The rate at which adiabatic cooling occurs with increasing altitude for wet air (air containing clouds or other visible forms of moisture) is called the wet adiabatic lapse rate, the moist adiabatic lapse rate, or the saturated adiabatic 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.
How does air temperature affect the dew point?
Temperature (dry adiabatic lapse rate) changes at about 2 per degree F per 1000 ft, dew point more slowly (saturated adiabatic lapse rate), at about 3 degree F per 1000 ft. See http://en.wikipedia.org/wiki/Adiabatic_lapse_rate. jb
Stability prevails when the environmental lapse rate is?
Stability prevails when the environmental lapse rate is less than the adiabatic lapse rate. This means that the temperature of the surrounding air decreases at a slower rate with altitude compared to the dry or moist adiabatic lapse rates, resulting in a more stable atmosphere.
Why is the lapse rate of moist air less than that of the dry air?
I think maritime polarWhen dry air is lifted, the temperature drops at the dry adiabatic lapse rate. If the lifted air is moist and eventually becomes saturated, then water vapor will start to condense. Energy is released when water vapor turns from solid to liquid (opposite of needing to add energy to liquid to make it evaporate, such as when you have to turn up the temperature on a stove to boil water). This release of energy - the "latent heat of vaporization" - warms the air, so the lapse rate is less for saturated air.
The rate of temperature change (0.6 degrees C for every 100 m) of saturated air as it rises or falls is the moist-adiabatic?
lapse rate
The rate of temperature change 0.6 degrees C for every 100 m of saturated air as it rises or falls is the moist adiabatic?
That statement describes the environmental lapse rate of saturated air, also known as the moist adiabatic lapse rate. This rate signifies how quickly the temperature of saturated air changes as it ascends or descends through the atmosphere under adiabatic conditions. The specific value of 0.6 degrees Celsius per 100 meters is a typical approximation for the moist adiabatic lapse rate.
Why is the saturated adiabatic lapse rate lower than the unsaturated adiabatic lapse rate?
The saturated adiabatic lapse rate is lower than the unsaturated adiabatic lapse rate because when air is saturated with moisture, the release of latent heat from condensation offsets some of the cooling that would normally occur as the air rises. This results in a slower rate of temperature decrease with height compared to unsaturated air.
The rate of temperature change 0.6 degrees C for every 100 m of saturated air as it rises or falls is the moist-adiabatic?
Correct.

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.
Is the adiabatic lapse rate higher when its cloudy or not?
There are two types of adiabatic lapse rates...wet and dry. (wet is also referred to as saturated or moist) To the extent that the cloudiness your question refers to represents saturated air, then no, the wet adiabatic lapse rate would be lower (approximately 1.5C/1000') than the dry adiabatic lapse rate (approximately 3C/1000').
Why temperature of air parcel increase during the wet adiabatic lapse ratev?
The temperature of an air parcel increases during the wet adiabatic lapse rate because as the parcel rises and expands, it cools down. If the air is saturated with water vapor, latent heat is released as the water vapor condenses into water droplets. This latent heat warms the air parcel, causing the temperature to increase instead of decrease as it would in the dry adiabatic lapse rate.
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.
