Hello Gabrielle, Congratulations on yourst Very good channel, both for ATPL & 737 info. This topic (ELR, DALR. SALR) was one of my "nightmares" during my ATPL Conversion (ICAO to EASA), luckily just finished...combined with WX fronts changes (Wind, Temp, Pressure changes, etc). Keep them coming, specially on the 737 tech & flying info !
Hey, thanks for watching!! I'm not where if there is any chart that shows you if the Atmpshere is stable or unstable. To get these infos I would check a Meteo station. Could you elablorate a bit more the questions #2? I wish you a great day!
Amazing video. So, in this case if I have either DALR or SALR higher than ELR I will have unstable air? And, DALR or SALR lower than ELR I will have stable air as in an inversion?
Hey, glad you like it!! If the ELR is higher you actually have stable air because the parcel of air, once raised, will colder and heavier and it will go back down..
Thank you for the video, captain! I have a question. Are the DALR and the SALR constant values of 3 and 1,5 degrees celsius per 1000ft, just like the EALR is 2 degrees celsius per 1000ft? To frame it differently, are the DALR and SALR values always the same?
You are more than welcome!! Theoretically yes, however in real life they change, like the Environmental lapse rate of 2deg per 1000feet. I wish you a great day!!
quick question captain how did they measure the lapse rate or how did they find out the value of the corresponding rate in celsius and in fahrenheit? i tried to convert let say the standard lapse rate of of 2C per 1000 feet to its corresponding rate in fahrenheit which is 3.5F per 1000 feet and the answer won't be the same.
Hey, thanks for watching!! I'm not an Meteorologist, so I don't really the details of how the get the lapse rate info, however, I guess the use the meteo station with a specific equipment that is capable to measure the weather condition with the Altitude (in the old days they used a "balloon" that was connect to the ground station). Check again you conversion from Celsius to Fahrenheit..I wish you a great day
hi captain! so if an airmass is warmer than surrounding air then it will keep climbing using dry adiabatic lapse rate ... what if an airmass and the surrounding air mass has the same temperature ..is it climbs using the environmental lapse rate and once reaches the dew point becomes cloud and still keeps climbing (cloud) unless atmosphere temperature and its temperature reaches the same ...
Hey, thanks for watching and the comment!! If an Air mass is warmer than the surrounding Air it will climb.. if the mass of Air is dry it will climb with a DALR. if the Air mass has the same temperature of the surrounding Air it should stay at the same level. I wish you a great day

👇Comment below with your questions and thoughts👇
I think in the last example you used the figure of 10.5 degs instead of 11 degs when going from 3k to 4k using the SLR.
I love your work sir. This helps soo much!! Please don't quit UA-cam ever! Us student pilots need you!
Many thanks for your great support! I'm very happy to see that the videos are helping! I wish you a great day!
Superb , you’re simply amazing. High recommended for those who are doing refreshment trainings

I'm glad to read that the videos are helping you!! Many thanks for watching and the comment!!
This is a great explanation. I understood it straight away 👍
Thanks for a great explained video Capt Gabriele... Have a nice weekend... 🙏
I hope you are great!! Many thanks for watching and the kind comment! I wish you a great day!!
I’m writting my PPL written in 3 days and just refreshing my knowledge on meteorology,great video!
Many thanks for the support!! I'm happy to see that the videos are helping
Thanks Cap, explaind very well!✌
Exactly what I am currently studying (my last ATPL exam MET) -- another useful video to improve my knowledge. Grazie mille !
That's great!!! I'm happy to read you are at the end of your ATPL!! Keep up the good work 💪
I’m preparing for my CPL met exam and I can say you made it very easy to understand. Thank you captain 👨✈️
Glad to read that! You are very welcome
Brilliant! Simple and straight to the point. Thanks a lot for your explanations. Keep up the good work
I'm glad you liked the video!! Thanks for watching and the comment!!
Thank you very much for that great video !
You're welcome
Very good explanation; it's a complicated topic, but calculations will provide a clear view of what kind of weather will emerge.
Many thanks for watching and the comment!! I'm glad the video helped.
Captain, wonderfull video, extremely helpfull with my ATPL 050 - Meteorology course. You've earned my sub! Please keep up the good work!
I'm glad it helped you!! Welcome on board
Great explanation and very clear! Thank you very much
You are very welcome!!
Very useful thank you :)
You are very welcome!
Love the presentation. Many thanks.
You are very welcome!
Thank you for this information!)
You are very welcome!!
Very helpful presentation- thank you!
Glad you liked the video..You are more than welcome
Perfect explanation, Thanks!
Glad you enjoyed the video!! Thanks for watching and the comment!
I have two questions.
1.Where can I get atmospheric stability and unstability data?
2. How can I draw dry adiabatic and environmental lapse rate data?
Hey, thanks for watching!! I'm not where if there is any chart that shows you if the Atmpshere is stable or unstable. To get these infos I would check a Meteo station. Could you elablorate a bit more the questions #2? I wish you a great day!
life saver thank you
this vdo is also helpful for mariners
a bit confusing at 17:20. Once the air parcel reached its dew point of 15C, wouldn't the DLR become SLR?
Many Thanks Captain 🙏🙏🙏
You are very welcome! I hope the video helped you..
You explained it very well 👍
❤ 🇮🇳
Thank you very much!
comming back to my glider times :)
I'm sure there were great times! 👍
“Beautiful”😊
Amazing video. So, in this case if I have either DALR or SALR higher than ELR I will have unstable air? And, DALR or SALR lower than ELR I will have stable air as in an inversion?

thank you.
but how does DLR change to SLR
❤️
You are very welcome! It depends on the humidity
hi captain! what happens when an air mass is colder than the surrounding air ?
The mass of air is heavier so it will tend to go down
hi captain! so if an airmass is warmer than surrounding air then it will keep climbing using dry adiabatic lapse rate ... what if an airmass and the surrounding air mass has the same temperature ..is it climbs using the environmental lapse rate and once reaches the dew point becomes cloud and still keeps climbing (cloud) unless atmosphere temperature and its temperature reaches the same ...
