After bashing my head against the Skew-T long enough, I found this video... absolutely perfectly taught!
The information in this video made my brain explode several times - but nevertheless this is the clearest, most concise video explanation of the basic parameters of a skew chart I've seen, and I've seen several at this point, so I'm *extremely* grateful. Well done! Thank you!
Phenomenal explanation, mouse movement, visualization: 10/10
I have watched several videos on SkewT, and this one has been the best!
Absolutely great. Thanks
As a paraglider looking to distinguish Strong sharp thermals from thermals that are safe for my wing and level of experience I immediately recognized that a tephigram chart will reveal what I need to know,
Your explanation although mind blowing has given me my 1st glimpse at realizing how to get this info. I've got a lot further to go at understanding and visualizing the terminology but your video has given me my 1st glimpse at understanding how to read these charts for SAFE thermals. THANK YOU!!
As a storm-chaser now into my 30s, I've put off learning about this stuff for far too long! Your video on this subject is the clearest and best I've seen so far, thanks very much!
Thank you for this video. I agree with others, it's the best explanation I've found for a newbie to sounding diagrams. I'll need to keep re-watching but at least I 'm beginning to see daylight through the clouds!!😲😄
very very good video!! I learnt so much more than what my professors taught in 8 weeks in this 11 min video
I can't believe that I actually understood how this works! 😲 And english isn't even my native language! 😆
Though, I probably won't remember all of the information good enough to use it "fluently". But that's alright, the replay button is free to use anyway! 😋
Thank you for giving an excellent lesson! 👏🙂
Best explanation on youtube, hands-down
Thank you!
I keep on getting confused with this.
I am tired of listening to my tutors voice when rewatching his videos.
I very much enjoyed yours!
All the best to you :)
Superb. Thanks.
Perhaps the best explanation I have seen, yet. Thanks for this!
Thank you! This is a great little summary for those of us studying for met exams. It's a perfect review of the basics.
I always had trouble understanding the mixing ratio, this cleared it up very well for me. Thank you!
Best explanation I've found so far, thanks :D
Agree with other comments..great and clear explanation of Skew-T diagram! Thanks! 👍
Thank you for this, truly.
very good !
thank you !
Thanks for the awesome and clear explanation. 👍👍
Really good explanation
Excellent SkewT class. Really really good. Thank you so much for sharing.
this was incredibly helpful, thank you!
Excellent video, mate! Thanks
This was some really good info, thanks for posting
This is really good, thank you!
Thank you. This definitely helped me.
Part two when? This was an amazing explanation of it! Thank you so much Dr.
Good for basics and improved visualization for understanding CAPE and some other lift parameters. BUT - -you should now assume we learned all the parameters plotted on the chart and look some DP and Temp patterns for pilots for prediction of Icing, snow, rain layers, and IMC, cloud conditions at various levels as we in GA wish to select altitudes for safe flight.
From observations I can see where cloud layers might be, tops, snow that turns into mist below freezing level, possible turbulence layers where winds aloft shift rapidly in velocity (speed&direction) but there are many other possibilities to be identified quickly on a Skew-t chart. Using an app along a flight path I can get the simulated changes and it is helpful as you pointed out - it is always changing.
Thanks again and I look forward for a more advanced visual pattern interpretation now that you have done the basics so well.
Amazing how much data can fit on this graph. Great video.
so helpful explanations!! keep going
thank you
you rock Patrick!
LOved it bhae.. dhanyabad. Wish I saw this before,.
holy crap. this is not for amateurs.
Great explanation
Well done..
Nice job!
tysm
I LOVE
Thank you very much : best info I found find. Excellent. But I am still missing one point : Where do the two initial dew points (the 2 green dots) come from ? Are they external data or are they deducted from the graph. My understanding are that they are external data. If I am understanding correctly, then the presentation would be more complete with better stating that this external. Or am I still missing something ? Thanks a lot anyway.
A quick question, the environmental temperature vs the parcel temperature. If the parcel temp is less than the environmental temperature, then you have CIN. Can you give examples of where the parcel temperature would be either higher or lower than the environmental temperature? In my mind these two temperature measurements are the same, unless the parcel is a theoretical item.
Thank you and great presentation.
Thanks. If I want to capture this in a program, which equations do I use for both the dry and the moist adiabatic lines? I think the dry line is the Poisson equation. Not sure how to approach the moist adiabatic line. Any link to a decription of the physics equation would be welcome.
Hello Patrick. Nice video. Would you mind sharing the tool used to create the Skew-T chart? I notice it has some tools in the lower left of the window you to edit and change slides. Thanks.
Thanks! It's just PowerPoint and the image here: www.wikiwand.com/en/Skew-T_log-P_diagram
@@pbrown111 hello, how can I calculate work done between ınp and T ? please help me
@@mehmetceylanm Hi, I'm not sure there's enough in this diagram to give you the entropy information you'd need to calculate work done, as you could in a true T-s diagram. But I'll happily stand corrected, anyone??
How do we measure pressure values less than 100 mb in oblique T-Log (p) diagrams?
hi, how can ı calculate work done between ınP and T ? please help me ?
How to calculate the area from the plot?
thanks for not dumbing it down... sick of explanations that are just vague
This is great. However, it should be noted for lazy amateur meteorologists that many skew-T diagrams list the CAPE, Lifted Index and Total Totals values on the chart itself so you don’t need to know how to read them or do any kind of analysis except looking up what the numbers mean😆
I would also like to add that the density of a saturated parcel does not only depend on it's temperature, The amount of liquid/solid water within it increases its density and thereby reduces the buoyancy.
At high mixing ratio's this effect can be very significant and prevent convection even though it has reached the LFC. Example sounding: www.meteociel.fr/cartes_obs/sondage_display.php?id=7761&date=1601290800
