| A formal definition from the ''Glossary of Meteorology''<ref name="Glossary of Meteorology">{{cite book|author=Todd S. Glickman|title=Glossary of Meteorology|edition=2nd|publisher=[[American Meteorological Society]], [[Boston]]|date=June 2000|isbn=1-878220-34-9}} [http://www.ametsoc.org/pubs/glossary_index.html (Glossary of Meteorology)]</ref> is:
| |
| :The decrease of an atmospheric variable with height, the variable being temperature unless otherwise specified.
| |
| | |
| In the lower regions of the atmosphere (up to altitudes of approximately 40,000 feet [12 km]), temperature decreases with altitude at a fairly uniform rate. Because the atmosphere is warmed by convection from [[Earth]]'s surface, this lapse or reduction in temperature is normal with increasing distance from the conductive source.
| |
| | |
| Although the actual atmospheric lapse rate varies, under normal atmospheric conditions the average atmospheric lapse rate results in a temperature decrease of 3.5°F/1,000 ft (6.4°C/km) of [[altitude]].
| |
| | |
| The measurable lapse rate is affected by the moisture content of the [[air]] ([[humidity]]). A dry lapse rate of 5.5°F/1,000 ft (10°C/km) is often used to calculate temperature changes in air not at 100% relative humidity. A wet lapse rate of 3°F/1,000 ft (5.5°C/km) is used to calculate the temperature changes in air that is saturated (i.e., air at 100% relative humidity). Although actual lapse rates do not strictly follow these guidelines, they present a model sufficiently accurate to predict temperate changes associated with updrafts and downdrafts. This differential lapse rate (dependent upon both difference in conductive heating and adiabatic expansion and compression) results in the formation of warm downslope winds (e.g., [[Chinook winds]], [[Santa Ana winds]], etc.).
| |
| The atmospheric lapse rate, combined with adiabatic cooling and heating of air related to the expansion and compression of atmospheric gases, present a unified model explaining the cooling of air as it moves aloft and the heating of air as it descends downslope.
| |
| | |
| Atmospheric stability can be measured in terms of lapse rates (i.e., the temperature differences associated with vertical movement of air). The atmosphere is considered conditionally unstable where the environmental lapse rate causes a slower decrease in temperature with altitude than the dry adiabatic lapse rate, as long as no latent heat is released (i.e. the saturated adiabatic lapse rate applies). Unconditional instability results when the dry adiabatic lapse rate causes air to cool slower than the environmental lapse rate, so air will continue to rise until it reaches the same temperature as its surroundings. Where the saturated adiabatic lapse rate is greater than the environmental lapse rate, the air cools faster than its environment and thus returns to its original position, irrespective of its moisture content.
| |
| | |
| Although the atmospheric lapse rate (also known as the environmental lapse rate) is most often used to characterize temperature changes, many properties (e.g. [[atmospheric pressure]]) can also be profiled by lapse rates.
| |
| | |
| == Mathematical definition ==
| |
| In general, a lapse rate is the negative of the rate of temperature change with altitude change, thus:
| |
| | |
| :<math>\gamma = -\frac{dT}{dz}</math>
| |
| | |
| where <math>\gamma</math> is the lapse rate given in [[physical unit|unit]]s of temperature divided by units of altitude, ''T'' = temperature, and ''z'' = altitude.
| |
| | |
| <br>Note: In some cases, <math>\Gamma</math> or <math>\alpha</math> can be used to represent the adiabatic lapse rate in order to avoid confusion with other terms symbolized by <math>\gamma</math>, such as the [[Heat capacity ratio|specific heat ratio]]<ref>{{cite book | author=Salomons, Erik M. | title=Computational Atmospheric Acoustics | edition=1st | publisher=Kluwer Academic Publishers| year=2001 | isbn=1-4020-0390-0}}</ref> or the [[psychrometric constant]].<ref>{{cite book | author=Stull, Roland B. | title=An Introduction to Boundary Layer Meteorology | edition=1st | publisher=Kluwer Academic Publishers| year=2001 | isbn=90-277-2769-4}}</ref> | |
| | |
| == Types of lapse rates ==
| |
| There are two types of lapse rate:
| |
| * Environmental lapse rate – which refers to the actual change of temperature with altitude for the stationary atmosphere (i.e. the [[temperature gradient]])
| |
| * The '''[[adiabatic process|adiabatic]] lapse rates''' – which refer to the change in temperature of a parcel of air as it moves upwards (or downwards) without exchanging heat with its surroundings. The temperature change that occurs within the air parcel reflects the adjusting balance between '''[[potential energy]]''' and '''[[kinetic energy]]''' of the molecules of gas that comprise the moving air mass. There are two adiabatic rates:<ref name=IUPAC>[http://goldbook.iupac.org/A00144.html Adiabatic Lapse Rate, [[IUPAC]] Goldbook]</ref>
| |
| ** Dry adiabatic lapse rate
| |
| ** Moist (or saturated) adiabatic lapse rate
| |
| | |
| === 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. As an average, the [[International Civil Aviation Organization]] (ICAO) defines an international standard atmosphere (ISA) with a temperature lapse rate of {{nowrap|6.49 K(°C)/1,000 m}}{{Citation needed|date=August 2011}} {{nowrap|(3.56 °F}} or {{nowrap|1.98 K(°C)/1,000 Ft)}} from sea level to 11 km {{nowrap|(36,090 ft)}}. From 11 km {{nowrap|(36,090 ft}} or {{nowrap|6.8 mi)}} up to 20 km {{nowrap|(65,620 ft}} or {{nowrap|12.4 mi)}}, the constant temperature is {{nowrap|−56.5 °C}} {{nowrap|(−69.7 °F)}}, which is the lowest assumed temperature in the ISA. The [[ICAO Standard Atmosphere|standard atmosphere]] contains no moisture. Unlike the idealized ISA, the temperature of the actual atmosphere does not always fall at a uniform rate with height. For example, there can be an [[Temperature inversion|inversion]] layer in which the temperature increases with altitude.
| |
| | |
| === Dry adiabatic lapse rate ===
| |
| [[File:Emagram.GIF|thumb|350px|right|[[Emagram]] diagram showing variation of dry adiabats (bold lines) and moist adiabats (dash lines) according to pressure and temperature]]
| |
| The '''dry adiabatic lapse rate''' (DALR) is the rate of temperature decrease with altitude for a [[air parcel|parcel]] of dry or unsaturated air rising under adiabatic conditions. Unsaturated air has less than 100% [[relative humidity]]; i.e. its actual temperature is higher than its [[dew point]]. The term ''adiabatic'' means that no heat transfer occurs into or out of the parcel. Air has low [[thermal conductivity]], and the bodies of air involved are very large, so transfer of heat by [[heat conduction|conduction]] is negligibly small.
| |
| | |
| Under these conditions when the air rises (for instance, by [[Atmospheric convection|convection]]) it expands, because the pressure is lower at higher altitudes. As the air parcel expands, it pushes on the air around it, doing [[Work (thermodynamics)|work]] (thermodynamics). Since the parcel does work but gains no heat, it loses [[internal energy]] so that its temperature decreases. The rate of temperature decrease is {{nowrap|9.8 °C/km}} ({{nowrap|5.38 °F}} per 1,000 ft) (3.0°C/1,000 ft). The reverse occurs for a sinking parcel of air.<ref name="DLA">Danielson, Levin, and Abrams, ''Meteorology'', McGraw Hill, 2003</ref>
| |
| | |
| Since for adiabatic process:
| |
| :<math>P dV = -V dP / \gamma</math>
| |
| | |
| the [[first law of thermodynamics]] can be written as
| |
| :<math>n c_v dT - V dp/ \gamma = 0</math>
| |
| | |
| Also since :<math>\alpha = V/n</math> and :<math>\gamma = c_p/c_v</math>
| |
| we can show that:
| |
| :<math>c_p dT - \alpha dP = 0</math>
| |
| | |
| where ''<math>c_p</math>'' is the specific heat at constant pressure and ''<math>\alpha</math>'' is the [[specific volume]].
| |
| | |
| Assuming an atmosphere in [[hydrostatic equilibrium]]:<ref name="LL">Landau and Lifshitz, ''Fluid Mechanics'', Pergamon, 1979</ref>
| |
| | |
| :<math> dP = - \rho g dz</math>
| |
| | |
| where ''g'' is the [[standard gravity]] and ''<math>\rho</math>'' is the density. Combining these two equations to eliminate the pressure, one arrives at the result for the DALR,<ref>Kittel and Kroemer, ''Thermal Physics'', Freeman, 1980; [http://books.google.com/books?id=c0R79nyOoNMC&lpg=PP1&dq=Kittel%20and%20Kroemer%2C%20Thermal%20Physics%2C&pg=PA179#v=onepage&q&f=false chapter 6, problem 11]</ref>
| |
| :<math>\Gamma_d = -\frac{dT}{dz}= \frac{g}{c_p} = 9.8 \ ^{\circ}\mathrm{C}/\mathrm{km}</math>.
| |
| | |
| === Saturated adiabatic lapse rate ===
| |
| When the air is [[saturation (chemistry)|saturated]] with [[water vapor]] (at its [[dew point]]), the '''moist adiabatic lapse rate''' (MALR) or '''saturated adiabatic lapse rate''' (SALR) applies. This lapse rate varies strongly with temperature. A typical value is around {{nowrap|5 °C/km}} {{nowrap|(2.7 °F/1,000 ft)}} (1.5°C/1,000 ft).
| |
| | |
| The reason for the difference between the dry and moist adiabatic lapse rate values is that [[latent heat]] is released when water condenses, thus decreasing the rate of temperature drop as altitude increases. This heat release process is an important source of energy in the development of thunderstorms. An unsaturated parcel of air of given temperature, altitude and moisture content below that of the corresponding dewpoint cools at the ''dry adiabatic lapse rate'' as altitude increases until the dewpoint line for the given moisture content is intersected. As the water vapor then starts condensing the air parcel subsequently cools at the slower ''moist adiabatic lapse rate'' if the altitude increases further.
| |
| | |
| The saturated adiabatic lapse rate is given approximately by this equation from the glossary of the American Meteorology Society:<ref>[http://amsglossary.allenpress.com/glossary/search?p=1&query=moist-adiabatic+lapse&submit=Search Glossary of Meteorology]</ref>

| == Significance in meteorology ==
| |
| The varying environmental lapse rates throughout the Earth's atmosphere are of critical importance in [[meteorology]], particularly within the [[troposphere]]. They are used to determine if the [[air parcel|parcel]] of rising air will rise high enough for its water to condense to form [[cloud]]s, and, having formed clouds, whether the air will continue to rise and form bigger shower clouds, and whether these clouds will get even bigger and form [[cumulonimbus cloud]]s (thunder clouds).
| |
| | |
| As unsaturated air rises, its temperature drops at the dry adiabatic rate. The [[dew point]] also drops (as a result of decreasing air pressure) but much more slowly, typically about {{nowrap|−2 °C}} per 1,000 m. If unsaturated air rises far enough, eventually its temperature will reach its [[dew point]], and condensation will begin to form. This altitude is known as the '''[[lifting condensation level]]''' ('''LCL''') when mechanical lift is present and the '''[[convective condensation level]]''' ('''CCL''') when mechanical lift is absent, in which case, the parcel must be heated from below to its [[convective temperature]]. The [[cloud base]] will be somewhere within the layer bounded by these parameters.
| |
| | |
| The difference between the dry adiabatic lapse rate and the rate at which the [[dew point]] drops is around {{nowrap|8 °C}} per 1,000 m. Given a difference in temperature and [[dew point]] readings on the ground, one can easily find the LCL by multiplying the difference by 125 m/°C.
| |
| | |
| If the environmental lapse rate is less than the moist adiabatic lapse rate, the air is absolutely stable — rising air will cool faster than the surrounding air and lose [[buoyancy]]. This often happens in the early morning, when the air near the ground has cooled overnight. Cloud formation in stable air is unlikely.
| |
| | |
| If the environmental lapse rate is between the moist and dry adiabatic lapse rates, the air is conditionally unstable — an unsaturated parcel of air does not have sufficient buoyancy to rise to the LCL or CCL, and it is stable to weak vertical displacements in either direction. If the parcel is saturated it is unstable and will rise to the LCL or CCL, and either be halted due to an [[Inversion (meteorology)|inversion layer]] of [[convective inhibition]], or if lifting continues, deep, moist convection (DMC) may ensue, as a parcel rises to the '''[[level of free convection]]''' ('''LFC'''), after which it enters the [[free convective layer]] (FCL) and usually rises to the '''[[equilibrium level]]''' ('''EL''').
| |
| | |
| If the environmental lapse rate is larger than the dry adiabatic lapse rate, it has a superadiabatic lapse rate, the air is absolutely unstable — a parcel of air will gain buoyancy as it rises both below and above the lifting condensation level or convective condensation level. This often happens in the afternoon over many land masses. In these conditions, the likelihood of [[cumulus cloud]]s, showers or even [[thunderstorm]]s is increased.
| |
| | |
| Meteorologists use [[radiosonde]]s to measure the environmental lapse rate and compare it to the predicted adiabatic lapse rate to forecast the likelihood that air will rise. Charts of the environmental lapse rate are known as [[thermodynamic diagrams]], examples of which include [[Skew-T log-P diagram]]s and [[tephigram]]s. (See also [[Thermals]]).
| |
| | |
| The difference in moist adiabatic lapse rate and the dry rate is the cause of [[foehn wind]] phenomenon (also known as "[[Chinook wind]]s" in parts of North America).
