For those who are still confused. Relative humidity is the amount of water vapour in the air with respect to the actual water holding capacity of the air at a given temperature. Higher temperature can hold more water vapour. Lower temperature holds less. RH does not tell you how much water vapour is in thr air. Dew point on the other hand tells you, for given amount of water vapour what is the lowest temperature at which the air gets fully saturated. This tells us how much vapour is actually in the air. At 50°C air temperature the dew point can be 45°C, if the RH is very high. This means there is no much vapour in the air that only a 5° C drop in temperature can result to 100% RH. Also, at 100% RH, the dew point is equal to the wet bulb temperature
It is not yet noon here, however, I am going to begin a stringent drinking regiment throughout the remainder of the day, and evening Intel I am capable of recapitulating this information….thanks for the video…🥃🥃🥃🥃🥃
Why add music? It's a big distraction. 0:47 she gabbles too fast and doesn't explain dew point properly. This video could easily have been so much better. Meanwhile, I'm searching for another explanation of dew point.
Jen, Thank you. There has been little success in me finding out why one day it could be 80° with a Relative Humidity of 60% and a Dew Point of 68° and I feel like I am trying to breathe in thick air. I struggle and have to limit my outdoor activities. So when they warn us to keep the elderly, small children, and people with respiratory and/or heart disease inside where the A/C can offer some relief - that's where I live. Yet there are days that seem to be near as warm with a little lower humidity and a dew point around 50 and I can breathe great. Thank you so very much for the graphics and the effort put into making this fun for kids of all ages. I hope to see more on these and other topics and I consider you the Dew Point guru of TWC and WU. And please do not let the hecklers and bored people get you down. You are a well respected scientist and meteorologist with a pleasant brightness around everything you report and teach. Shine on my friend, SHINE ON. Best Regards, Dave and Cathy Williams
Please do a part B with a little more detail and speaking a tad slower. How is the air (humidity and dew point and whatever else contributes to how it feels) different in lets say Portland, Oregon as compared to Pensacola, Florida? This may be a different topic, but how is much of Texas so dry on the ground and with fewer lush plants, yet they call it humid?
Dew point, Wet bulb, heat index. Just get it straight guys Dew point is unreliable and doesn't say much for your feel tp. The best is heat index which actually gives you a rough idea of what heat is feeling like.
Stick with humidity. Forget few point. Dew point is the temperature at which dew will form. That's why it's appropriately called "The Dew Point". Relative Humidity is a better way. If I held up a glass half full of water, the human brain can grasp " 50% " full. With dew point, you have to do all kinds of math and still can't figure it out. Relative Humidity is old school and better
"The percentage of moisture in the air" and "the amount of moisture in the air" are exactly the same, given a fixed volume and temperature. A better definition of the dew point is the temperature at which the relative humidity is 100%, i.e., the air is saturated. A better definition of relative humidity is the amount of moisture in the air compared to the maximum amount the air can "hold" at that temperature. Yes, this video is very confusing, and I don't believe it would be helpful to someone who doesn't already understand vapor pressures and thermodynamics. I would even bet my life savings that she didn't fully understand either. There are much better explanations of this topic on UA-cam.
I think it is the temperature of air with RH 100% . So taking a particular outside temperature like 50° and comparing with 2 different dew points 20° and 25° . 25° is more closer to the outside temperature so is the RH %(i was considering this on a scale basis) , please corect me if i am wrong
No, they are not. Percentage is always a measure of a certain amount in comparison to a total whole, like a slice of a pie. For example, 1 cup out of 2 total cups, 2 cups out of 4, 5 out of 10, etc. all are equal to 50%. But the amount of each percentage is different. 1 cup is obviously more than 2 cups, and 5 cups are more than 2. So the amount of each is different, but because they divide evenly out of the total (1/2, 2/4, 5/10), the percentage is the same. In the woman's example in the video, the percentage of water in each cup is half a glass, so 50% each. But the amount is different because the left cup is larger than the right cup. So if each cup has half a glass of water, the water in the left cup would be much more in amount than the water in the right cup. That's how percent and amount differ. Hope that makes sense.
V Poor explanation! Relative Humidity is not the % of water vapour in the air, it's the amount of water in the air as a percentage of the total amount of water that can be held in the air at a given temperature.
seriously, I think she is explaining it all wrong. what she is explaining is RELATIVE humidity and not dew point. dew point is the temperature at which , on that particular day DEW can form. it has a relationship to the humidity in the air, and I wanted that formula. she's explaining garbage.
🤣🤣🤣🤣🤣🤣🤣🤣 Sorry... Relative humidity is amount of moisture present in air to the most it can hold at paricular temperature. Moisture holding capacity of air is temperature dependent at high temperature air molecules expand so there is more space between molecules for moisture. But at particular temperature it has certain capacity tol hold vapours. So SUPPOSE AIR CAN HOLD 100 MOLECULES OF WATER VAPOUR AT PARTICULAR TEMPERATURE BUT IT HAVE 50 RIGHT NOW RELATIVE HUMIDITY WILL BE 50% NOW THE DEW POINT... AS Temperature decreases air molecules come closer and it's water vapour holding capacity also decreases. So suppose air can hold 100 molecules at particular temperature it's also it's dew point because if you decrease temperature air molecules will come closer and water will get drain. So at dew point rh is always 100℅ as its holding the most vapour in it at that temperature

more confused than before.
lmaoa
😂
😂 me too!
I agree that was weird@@fuufoo
😂😂😂😂 seriously!
I don't know everyone in the comments saying it's confusing, I find it very helpful. Thank you!
How can anyone pay attention with all the arbitrary sound effects and graphics?
This is confusing 😂
For those who are still confused. Relative humidity is the amount of water vapour in the air with respect to the actual water holding capacity of the air at a given temperature.

Understood the first half, the rest I was reading another Language.
Just telling us again, what the video said, doesn't help.
Started really confusing but then nailed it with the hands-on experiment. Kudos.
I felt the Indian guy with the PowerPoint was more informative than this.
😂😂😂
I’ll never understand it lol but this video is probably the closest I’ll get to enlightenment on humidity vs dew point.
It is not yet noon here, however, I am going to begin a stringent drinking regiment throughout the remainder of the day, and evening Intel I am capable of recapitulating this information….thanks for the video…🥃🥃🥃🥃🥃
the animated graphics (text on swinging sign, with sound effect) is distracting and counterproductive
I think I was watching keeping up with the cardigans. “UM, like, I don’t get it…”
Great for definitions…. Less great for an indepth understanding. Can’t expect much from a 1:09 video
Terrible video, and the music made it worse.
One minute "lesson" and you know less in the end.
Why add music? It's a big distraction. 0:47 she gabbles too fast and doesn't explain dew point properly. This video could easily have been so much better. Meanwhile, I'm searching for another explanation of dew point.
The dew point where I was working the other day was like 84. I felt like I was going to drown walking around 😂😢
Really helpful.
Where is the 69 and 41 coming from in the video? (aka the calculations)
dew point is a temperature degree where air moisture condense into liquid form its not an amount
Left out the important points: RH is measured.
DP is a calculated.
Scientists favor RH (and Hg.)
TV weather casters like DP for some unknown reason.
FINALLY!!! I get it!!! Thank you.
Jen,

Simp
I’m glad it’s not just me.
I’m more confused
Very easy to understand, straight to the point.
This didn't explain anything, but had lots of annoying graphics and noises.
A temp of 85F and dew point of 55 feels comfortable but the same air temp but with a dew point of 75 is oppressive
I'm an engineer, and I'm confused. This was not helpful. Where is Hank Green?!
Please do a part B with a little more detail and speaking a tad slower.
How is the air (humidity and dew point and whatever else contributes to how it feels) different in lets say Portland, Oregon as compared to Pensacola, Florida?
This may be a different topic, but how is much of Texas so dry on the ground and with fewer lush plants, yet they call it humid?
thanks I needed that
Dew point, Wet bulb, heat index.
Just get it straight guys
Dew point is unreliable and doesn't say much for your feel tp.
The best is heat index which actually gives you a rough idea of what heat is feeling like.
Now I kno why sometimes it feel warmer in Chicago when it’s 30 degrees lol….
Jen Carfagno is awesome. I remember her first appearing overnights on the Weather Channel. This video though is absolutely no help. 🤷♂️🤦♂️🤣
I am still confused.
High humidity with air temperatures under 65F are still comfortable as the dew point is still below 65
Even she does not understand. Do not waste your time.

Why did you have to use two different sized cups? !
"The percentage of moisture in the air" and "the amount of moisture in the air" are exactly the same, given a fixed volume and temperature.
A better definition of the dew point is the temperature at which the relative humidity is 100%, i.e., the air is saturated.

oh my god ! doesn't expect this much tedious editing to explain this simple topic....great one

Both temps would be very comfortable. Are you Celius?
@@Kurio71 ya celcius
@@scoobydoow7988 A 30°C day with a dew point of 15° would be comfortable.
Dew points of 20°C plus are considered very humid
Anyways you can search up definitions
I still don't get it.
Totally inane obtuse ridiculous waste of time presentation.
is percentage and amount not literally the same meaning in English language?
No, they are not. Percentage is always a measure of a certain amount in comparison to a total whole, like a slice of a pie. For example, 1 cup out of 2 total cups, 2 cups out of 4, 5 out of 10, etc. all are equal to 50%.

Thank you for confusing
humidity index in metric??
finally ......we understand.
Yeah, this tells me nothing.
Next time, try Celcius, like normal humans
I guess I’ll
Never know
Thanks , didnt understand anything
My mind finds this sensory input threatening.
(Not from america)
Excellent explanation.
More confusion madam
Bruh who uses F use C
V Poor explanation! Relative Humidity is not the % of water vapour in the air, it's the amount of water in the air as a percentage of the total amount of water that can be held in the air at a given temperature.

76+ = les mis
This would only be a satisfactory explanation if you already knew what those terms meant and the video is so distracting
😮
More confusing 😂
all the people saying they're confused must have never read a book in their life.
I learned nothing from this
So wrong
Explains nothing. We-todd-it
she talks to fast!!!
Get rid of that ridiculous music!
she failed miserably at explaining
I'm upset! you made me lose 1:09 sec of my precious life watching this BS excuse for a presentation!
What a crappy explanation video 😮
