Talk:Planetary boundary layer

message: I'm preparing an article on convective mixing in the atmospheric boundary layer (ABL) as part of an UCLA class project (The Atmospheric Boundary Layer ). I already gathered some references in my sandbox. Any feedbacks would be really appreciated.  --Lethepku (talk) 22:50, 2 May 2014 (UTC)

message: The wind gradient article talks about microscale effects within the planetary boundary layer, and should likely be merged into this article.  Comments encouraged.  Thegreatdr 14:45, 8 June 2007 (UTC)

I am surprised Wiki does not have an article about Atmospheric Caps.  An atmospheric cap is important in meteorology and Michigan.  It defines the Planetary Boundary layer.  I am sure the NWS meteorologists have just missed an important topic.  I could not begin to write the story myself.  Ah ... ask Jim Cantorie he knows about these things.
Basically, an atmospheric cap is not just warm air aloft and cold air near the ground.  (See the links)  The Lower Peninsula of Michigan is between two of the largest glacial lakes.  (Taken together across the Straits of Mackinaw, The Largest Great Lake.)  At night our planetary boundary layer cools down because the sun is not shining, glacial lakes are cold and Relative Humidity is high.  In the daytime when the sun is shining the Lower Peninsula warms up, warm air rises in cool air to the cap.  Relative Humidifies are low because water vapor rises in air. We get either fair weather cumulous or stratus clouds depending on the strength of the cap.
I also wish the mathematicians would isolate their unknown variables in parametric equations I could just plug into my Decimal BASIC programs.  I forgot what to differentiate but I can still iterate.  — Preceding unsigned comment added by 75.133.90.215 (talk) 14:57, 2 June 2016 (UTC)

message: The current text in the article includes:
"Atmospheric stability occurring at night with radiative cooling tends to contain turbulent eddies vertically, increasing the wind gradient."
It might have been caused by a combination of some knowledge of meteorology and the fact that English is not my mother tongue, but reading the words "contain turbulent eddies" while knowing that radiative cooling tends to decrease turbulent eddy activity left me wondering for a while, until I realized that "to contain" can actually also mean "to restrain" and "to confine" apart from "to include as a part". So, might I suggest replacing "to contain" with another word, just to reduce the chances for readers to be wrongfooted?Redav (talk) 23:36, 20 July 2020 (UTC)
