This is the first time I see a graph like this, absolutely interesting. What I like also is the wind direction (I think) at the right of this graph that turns to west at higher altitudes, which confirms what I know about that. Super !
Incredible CAPE probably 3000 J/KG+ but that super dry layer at 750 would make it harder for storms to develop. If directional shear made this high CAPE environment favorable for supercells, those supercells would likely be LP types not HP because of that very dry air at 750. Great video btw for anyone who doesn't understand what CAPE is.
This is really neat stuff, and reminds me of my economics class in college. Supply/demand equilibrium point, and the "areas" between two lines - consumer surplus, producer surplus, deadweight loss, etc.
I had to look up lapse rate, or I wouldn't have known what you were talking about. I'll need to find another source to understand this because of my lack of exposure to the technical side of severe weather. I think this video is meant for people with some background education about extreme weather.
First of all, great video! I do have a question, though: looking at the moisture content at approx 800mb, would I have cloud development? Many thanks for your response. MIchael
Extremely interesting, thanks for explaining this. I still don't fully understand it, I'm still learning. Now...the lapse rate. What determines that? Where does it come from? Thanks.
Your welcome I'm glad i could help. The lapse rate is a rate at which the air needs to cool as you gain altitude to keep an air parcel warmer than it so it can keep rising. now when you have lapse rates of say 10 degrees celsius of cooling per 1km or more that air parcel will rapidly rise because it is a lot warmer than its environment.... Now what actually determines the lapse rate seems to be from a cold front making the upper air much cooler than the ground causing warmed up air from the ground to rise, and something that prevents rising such as a cap
Xenon 93 yes that s what he meant. And something he didn't mention. The lapse rate is changed based on how much moisture is in the air that's rising. More moisture takes more time to cool off than a parcel of air with less moisture. Look up videos on dry adiabatic and moist adiabatic lapse rates and you will really get it. There's a lot of great videos here on youtube with all kinds of graphics and such to make it easier for anyone to understand
Great video man! Thanks for that. How are these measured (i.e. some models plot J/kg). What do these value represent and seeing as a skew-T chart is usually an observation how is CAPE forecasted?
thanks! i am not totally sure to be honest. i think it forecasted by looking at how much the air will cool as you gain altitude (lapse rate) and how much moisture will be in the layers of the atmosphere (more moisture means air parcel will cool slower, keeping it warmer than its surrounding environment... allowing it to keep rising)
You mean for any one specific location at any point?? If so check out pivotal weather.com go to models, choose hrrr and click anywhere on the map and the skew t chart will pop up
@@Eastcentralstainingco Its a bit hard to explain without showing you in person, but on pivitalweather's models you select a time with the blue boxes on the top left of the screen. they basically are hour to time increments that you skip into the future for forecasting. You can look at the skew t chart at any hour and it just depends if your looking for something in particular. I mostly look at them if I'm going to be storm chasing and what to see how the atmosphere is predicted to be in the late afternoon.
I have spontaneously decided to learn everything I can about thunderstorms during quarantine, thanks for the explanation of cape
Always loved the weather, especially the violent weather. Thought i'd do the same!
doing the same thing lol, 2021 was my year of the cloud
I've been trying to learn for months never found a video actually telling me how thank you very much

Good, educational video 😃 Thank you 👍
Thanks. Very helpful in understanding CAPE.
Awesomely explained! Thanks! :D
Thank you for explaining this!
omg you saved my life..
Thank you! Very helpful.
Insane dry layer at 750mb
That's exactly what I thought when I found this sounding
First of all, great video!
I do have a question, though: looking at the moisture content at approx 800mb, would I have cloud development?
Many thanks for your response.

I would expect there will be a thin layer of stratus. It is a different mechanism from convective cloud.

+Trent, I think you meant to say "... to keep an air parcel warmer than its surroundings so it can keep rising" right ? :)

So, a lower in terms of height of the LFC depicts a greater chance of strong weather event?
Great video man! Thanks for that. How are these measured (i.e. some models plot J/kg). What do these value represent and seeing as a skew-T chart is usually an observation how is CAPE forecasted?

what is the reason when cape is available but no rain !
Where can I find local CAPE measurements?
You mean for any one specific location at any point?? If so check out pivotal weather.com go to models, choose hrrr and click anywhere on the map and the skew t chart will pop up
@@mxrider8393 thank you so much for taking the time to explain that.
When would I be looking at sket t chart of predictions? Example: would I be looking at the chart in the morning to predict the afternoon?

That dewpoint depression though
how can i make skew T in matlab
