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 dry adiabatic lapse rate?
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.
The wet adiabatic rate of cooling is less than the dry rate because?
of the release of latent heat
What occurs on the side of the mountain facing the wind?
Rain. The side facing the wind with experience a phenomenon known as adiabatic cooling. When this happens water is condensed out of the air and forms rain. The side facing away from the wind will experience adiabatic heating, where the air will get warmer and be able to hold more moisture, and therefore, that side experiences less rain. Most deserts, especially in the US, are as a result of adiabatic heating, and they are on the 'other side of the mountain' as the wind.
What are the environmental effects of coastal overpopulation?
Coastal overpopulation means1. Less fish in the sea 2.Less beaches for getting a suntan. 3.More work for lifeguards.
What is the temperature range of troposphere?
On average, temperature decreases with height in the troposphere. The troposphere is bounded by the earth's surface and the tropopause (located at about 150 millibars in the tropics and 300 mb at high latitudes). In the troposphere on any given day, there are various layers between the surface and the tropopause where the lapse rates are far from average (the average environmental lapse rate is near 6.5 degrees C/km). Rawinsonde weather balloons measure temperature as they rise (this is the plot of the environmental lapse rate). Under certain conditions, the lapse rate in the atmosphere (defined as the change in temperature with height) is much above or much below normal.
Stability prevails when the environmental lapse rate is?
less than the wet adiabatic rate.
What must the environmental lapse be in order for stability to prevail?
less than the wet adiabatic 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.
What environmental lapse rate does stability prevail?
less than the wet adiabotic rate

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.
Why do most low-level clouds have flat bases?
You can not see water vapor, which is a gas. As air cools uniformly with increasing height (the adiabatic lapse rate,for the cognoscenti), it can contain less water vapor. When it can't hold any more ,water condenses in tiny droplets.

What is adiabatic heating and cooling?
Adiabatic cooling happens as air mass expands with increasing elevation (because density of gases decreases farther into the atmosphere). As elevation increases, the air gets cooler because energy is drawn from the surroundings. Less dense air traps less heat resulting in this net cooling called adiabatic cooling. It occurs at an average of 6 degrees Celsius per 1000 meters, but it can vary.
