The dry adiabatic lapse rate (La)* on Venus is about 10.47K/km, and is similar to that of Earth. This is because the La is governed specific heat (Cp) of the atmospheric gasses and the planet's gravity (g). Specific heat (Cp) is the amount of heat energy in Joules required to raise the temperature of 1 kg of substance by 1 Kelvin. The equation is quite simple. La = g/Cp For Earth: Cp = 1.004 J/kg/K, g = 9.8 m/s2 Earth La = 9.76 K/km For Venus: Cp = 0.85 J/kg/K, g = 8.9 m/s2 Venus La = 10.47 K/km For Mars: Cp = 0.83 J/kg/K, g = 3.7 m/s2 Mars La = 4.50 K/km http://pds-atmospheres.nmsu.edu/education_and_outreach/encyclopedia/adiabatic_lapse_rate.htm The symbol for lapse rate is actually an upside-down L, but I don't know how to do scientific symbols on this browser.

How does the moist adiabatic lapse rate compare with the dry-adiabatic lapse rate?

The moist rate may be more or less, depending on the conditions.


What is dry adiabatic lapse rate?

A special process lapse rate of temperature, defined as the rate of decrease of temperature with height of a parcel of dry air lifted adiabatically through an atmosphere in hydrostatic equilibrium. Also known as adiabatic lapse rate; adiabatic rate.


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').

What is an adiabatic lapse rate?

An adiabiatic lapse rate is the rate of the decrease of temperature with height of a parcel of dry air lifted upward through the atmosphere with no addition or deletion of heat.


Explain the difference between environmental lapse rate and adiabatic?

Environment lapse rate is nothing but rate of reduction/decrease with height for an atmospheric variable, mostly temprature is considered.It will not sound good, if we don't discuss it mathematically,r = - dT/dH , which can be phrased as negative of the rate of change of temprature with change in altitude.T =Temprature, H = HeightOf course there are two types of lapse rate1.Environmental lapse rate - This actually refers to the actual change of temperature with altitude for the stationary atmosphere (i.e. the temperature gradient)The environmental lapse rate also represented as ELR, is the rate of reduction of temperature with height in the stationary atmosphere at a given time and location.2.The adiabatic lapse rate - This refer to the change in temperature of a mass of air as it moves upwards.Further there are two adiabatic rates:a.Dry adiabatic lapse rateThe dry adiabatic lapse rate also shorted as DALR is the rate of temperature decrease with height for a parcel of dry or unsaturated air rising under adiabatic conditions.b.Moist/saturated adiabatic lapse rateThis applies when the air is saturated with water vapor at said dew point also shorted as MALR or saturated adiabatic lapse rate - SALR.The following are the key differences:Environmental Lapse rate is change of temperature with altitute for a stable atmosphere where as adiabatic lapse rates is the change in temperature of a mass of air as it moves upwards.


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.

The rising and subsequent cooling of air at the rate of 10C per 1000 meters is called?

According to scientist Beethoven Salazar he said it was the dry adiabatic lapse rate.


Why is there a difference between the dry and moist adiabatic lapse rates?

Air that is rising at the dry adiabatic rate can simply cool at the rate at which the decreasing pressure forces it to. Once it cools to its dew point at the lifting condensation level, it must condense some of its moisture in order to cool anymore (it is already saturated at this point). Condensation is a process that releases latent heat into the atmosphere, warming the air. Therefore, this heat released counteracts some of the adiabatic cooling that continues to take place as the air rises, and the net effect is a rate of cooling that is reduced. This is the saturated (or moist) 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.
