 * Add a link to the wikipedia article on Monin-Obukhov length somewhere?

Reply: I added a section "Related articles", and put a link there. Geoalchimista (talk) 23:04, 10 June 2014 (UTC)

Obukhov Length section:
 * is the Dynamic sublayer the same as the surface layer? Saw those interchanged in the section.  Would recommend choosing one or the other for consistency.  — Preceding unsigned comment added by Kquinn1981 (talk • contribs) 20:45, 2 June 2014 (UTC)

Reply: They are the same in the context of this article. I changed them to "surface layer" for consistency. Geoalchimista (talk) 23:07, 10 June 2014 (UTC)

Governing Formulae section:
 * Class notes from lecture 15 (I think) say that Kh/Km is roughly equal to 1, though typically is around 0.75. You state in this section that Kh/Km is typically greater than 1.  — Preceding unsigned comment added by Kquinn1981 (talk • contribs) 20:48, 2 June 2014 (UTC)


 * Verified that random portions of article represent their cited sources
 * Article, to me, looks to take a neutral point of view

Grammar/Word-smithing for Lead Section:
 * Get rid of "The" in front of Monin-Obukhov in first sentence. Also, define Monin-Obukhov theory in this sentence by putting "(M-O Theory)" directly after Monin-Obukhov
 * Add a comma after "temperature" before "and turbulent fluxes" or, do something like "describes non-dimensionalized mean flow and temperature/turbulent fluxes"-will read a bit easier
 * Add "the" in front of "dimensionless height parameter"
 * Switch the order of A.M. Obukhov and A.S. Monin where you describe the origins of the name of the theory
 * Second sentence, just call it "Similarity theory" instead of "A similarity theory"
 * Second sentence, call it "the Buckingham Pi theorem"
 * Third sentence, you make similarity theory plural when you call it "Similarity theories". Call it "Similarity theory" to maintain consistency with second sentence.
 * Third sentence, change "relations in turbulent" to "relations between turbulent"
 * Second paragraph, first sentence: change "neutral boundary layer is logarithmic wind profile" to "neutral boundary layer is the logarithmic wind profile".
 * Second paragraph, first sentence: instead of using "i.e", change "i.e." to "which states that the ..."
 * Second sentence and final sentences in the paragraph: drop the "The" in front of "M-O similarity theory"
 * Define the Obukhov length in the second to last sentence in that paragraph by putting in "(L)"
 * Last sentence, second paragraph-use active voice, changing to something like "M-O similarity theory marked a significant landmark..., providing a theoretical basis...measurement techniques." — Preceding unsigned comment added by Kquinn1981 (talk • contribs) 22:44, 28 May 2014 (UTC)

The Obukhov length section:
 * "The Obukhov length was formulated upon Richardson's..." to "The Obukhov length was formulated using Richardson's..."
 * "The original equation for it was derived as," to "L can be derived as:"
 * "More precisely, virtual potential temperature is often used in substitution for temperature  so as to correct for the effects of pressure and water vapor changes." to "Virtual potential temperature  is often used instead of temperature T to correct for the effects of pressure and water vapor."
 * "The turbulent heat flux Q can be written as vertical eddy flux," to "Q can be written as vertical eddy flux,"
 * "The Obukhov length is itself a criterion for the stability condition of surface layer." to "The Obukhov length also acts as a criterion for the static stability of surface layer."
 * "with smaller L corresponding to larger deviation from neutral conditions." to "with smaller L values corresponding to larger deviations from neutral conditions."
 * "The Obukhov length L is used for non-dimensionalization of height Z in the similarity theory." to "The Obukhov length L is used for non-dimensionalization of height Z in similarity theory."

Governing formulae of the similarity relations:
 * Change title to "Governing formulae for similarity relations"
 * "The M–O similarity theory..." to "M–O similarity theory..."
 * "From Buckingham Pi theorem of dimensional analysis, two dimensionless group are formed from the basic parameter set" to "From the Buckingham Pi theorem of dimensional analysis, two dimensionless groups can be formed from:"
 * "Then a function is determined to empirically describe the relationship between the two dimensionless quantities, which is called a universal function." to "From there, a function  can be determined to empirically describe the relationship between the two dimensionless quantities, called a universal function."
 * "Similarly, a universal function can be defined..." to "Similarly, ...  can be defined..."
 * "The eddy diffusivity coefficients for momentum and heat fluxes are defined as follow," to "The eddy diffusivity coefficients for momentum and heat fluxes are defined as follows,"
 * "In a strict sense, Km does not equal Kh," to "Km and Kh can be related with the turbulent Prandtl number..."
 * "Practically, the universal functions need to be determined using experimental data when applying the M–O similarity theory." to "In reality, the universal functions need to be determined using experimental data when applying M–O similarity theory."
 * "...certain functional forms were proposed and widely accepted for fitting experimental data." to "certain functional forms have been proposed and are widely accepted for fitting experimental data."

Universal functions section:
 * Caption: get rid of "the" in front of "literature", or better yet, say "Universal functions for Monin-Obukhov similarity theory..."
 * "Several functional forms were proposed to represent the universal functions of the similarity theory." to "Several functional forms have been proposed to represent the universal functions of similarity theory."
 * "For sublayer with significant roughness, e.g. vegetated surfaces or urban area, the universal functions must be modified to include the effects of surface roughness[6].": Make "sublayer" and "urban area" plural.

Validations section: -Get rid of "Following the M–O similarity theory" and just keep "A myriad of ...", and add "M-O similarity theory." at the end of the sentence. -Active voice-change last sentence to something like "In general, these experimental efforts, field simulations, and computer simulations have generally validated M-O similarity theory."
 * "Following the M–O similarity theory, a myriad of experimental efforts were devoted to validation of the theory. The theory was generally well satisfied by field observations and computer simulations."

In field measurements section:
 * "The 1968 Kansas experiment has found great consistency between measurements and predictions from the similarity relations over the entire stability range of observations[7]." to "The 1968 Kansas experiment found great consistency between measurements and predictions from similarity for the entire range of stability values[7]."
 * Change "The experiment was set up in a flat wheat field in Kansas" to "A flat weight field in Kansas served as the experiment site, with winds measured by..."
 * Change "32m tall tower" to "32m tower"
 * Add "The" in front of "Temperature profile was also measured in a similar manner."
 * Change "The ratio of eddy diffusivities of heat an momentum was found to be approximately" to "Results from the Kansas field study indicated that the ratio of eddy diffusivities of heat and momentum equaled approximately 1.35 under neutral conditions."
 * This paragraph can be tightened up: "Later in 1973, another experimental campaign was set up at a flat site in northwestern Minnesota, where both ground-based and balloon observations were involved[10]. The observations for the surface layer were also in good agreement with theoretical predictions from the similarity relations."

Change it to something like: "A similar experiment was conducted in a flat field in northwestern Minnesota in 1973. This experiment used both ground and balloon-based observations of the surface layer and further validated the theoretical predictions from similarity." In large eddy simulations section:
 * Change "The simulation" to "These simulations indicate that temperature fields largely follow M-O similarity theory"
 * Make this another sentence and change to "However, velocity fields show significant anomalies from M–O similarity."

Limitations section:
 * First sentence, drop "The" and just call it "M-O similarity theory", and put sentence in the present tense ("was essentially" to "is essentially"), "an diagnostic empirical theory" to "a diagnostic...".
 * Third sentence, make "vegetated area" plural, "it can result" to "resulting in large..."
 * Last sentence, put in present tense
 * Second paragraph, first sentence, drop "the" in front of "M-O similarity theory"
 * Second sentence, put in present tense
