This must be the best explanation on dew point, rh and spread, I've ever heard. The coffee comparison was really helpful!

[@phil_adelphia215]

I watched a good number of videos like this and this was no doubt the best and easiest to understand. Much appreciated.

Even as an aside to aviation, this is just an amazing explanation of how clouds themselves form.

[@jackmosher7561]

...wow, the coffee analogy was absolutely on-point!

[@Skidmark_aviation]

I just had an exam on this yesterday. Great breakdown!

I’ve always understood this, but the coffee reference is an excellent way to actually visualize it and and put it in terms people can relate it to. I was actually drinking coffee when I watched this (I take my coffee 0% saturated). Non coffee drinkers could probably relate to making hot chocolate with the powder packets. Or… what kid hasn’t ever tried to see how much sugar they could dissolve in water and drink it?

[@pedrodasilva8382]

Thank you for that brilliant explanation

[@joshcaligaris]

I swear, i can watch 10 different videos on any topic and not understand it. I come to this guy and he explains whatever topic i need, perfectly.

[@nicholasbarbier3310]

love the analogy with coffee and sugar, well explained

[@AlexandreHenriquePinheiro]

This was the best. Thanks so much for the explanation!

[@alk672]

So why does the dew point fall slower with altitude than the temperature? Is that always the case?

[@janalexlayosa8679]

Love these kind of videos

[@jakew9887]

Excellent presentation. Thanks

[@jenniferveerasamy2887]

Amazing 👍🏽👍🏽😊

[@TomBombadiddle]

Nice explanation!

[@eliaselhaddad5166]

Why does Dew Point decrease as temperature decreases. What are the theoretical reasons?

[@RicardoCerveraBlanco]

So in order to condensate or dehumidify the water from the air the temperature has to be lower than the dew point?.

[@damonbaggs3296]

Not the whole story....and in my experience, not as simple as this explanation makes it out to be. I've seen temp/dew point at zero without the formation of "clouds" or fog more times than I have see with the same temp/dew point at zero with clouds or fog. So, this "within two degrees or less temp/dew point spread will create fog/clouds" isn't the entire truth. I personally don't know what other variables there are to this phenomenon... I just know there is more to it. Also, I've witness the TAF or MOS more often wrong with the prediction of fog then they are right.... so, there is that as well.
