2017 Hurricanes and Aerosols Simulation
Вставка

- How can you see the atmosphere? By tracking what is carried on the wind. Tiny aerosol particles such as smoke, dust, and sea salt are transported across the globe, making visible weather patterns and other normally invisible physical processes.
This visualization uses data from NASA satellites, combined with mathematical models in a computer simulation allowing scientists to study the physical processes in our atmosphere. By following the sea salt that is evaporated from the ocean, you can see the storms of the 2017 hurricane season.
During the same time, large fires in the Pacific Northwest released smoke into the atmosphere. Large weather patterns can transport these particles long distances: in early September, you can see a line of smoke from Oregon and Washington, down the Great Plains, through the South, and across the Atlantic to England.
Dust from the Sahara is also caught in storms sytems and moved from Africa to the Americas. Unlike the sea salt, however, the dust is removed from the center of the storm. The dust particles are absorbed by cloud droplets and then washed out as it rains.
Advances in computing speed allow scientists to include more details of these physical processes in their simulations of how the aerosols interact with the storm systems.

I heard before that dust from Africa fertilizes the Amazon forest in South America. Nice to see the actual dust movement. Awesome detailed video! Don't cut NASA's budget!!
It also helps water to condensate in the atmosphere faster, bringing more rain.
I'm glad it included Ophelia, was some crazy apocalyptic red sky over London and England that day.
It wasn't Ophelia, it was due to the wild fires in Portugal.
Ophelia brought the smoke that caused that visual effect
Strangething90 - I could hear Ophelia in one of *BigClivedotcom's* videos !!! Mind you, I was hit by Emily and Irma (and many others over the years) so I'm used to it but I imagine it was a shock to y'all on that side of the pond !!!
excy=use me boy, youa re a bit egocentric , it waéqs dfn ,opyt po,lmy in london my dudes
Scotty あ
This is just beautiful!! I look at it almost every night. The use of these tracers to see the overall turbulence of the atmosphere is just incredible - much more wonderful than just the hurricanes. Bravo to NASA Goddard!!
1:31 the Northern California fires begin
Love how Iceland becomes like a wall for Norway, amazing simulation. Pretty damn accurate too considering past weather events.
All that smoke from the BC forest fires... damn that is crazy.
Wow, I watched it again and again--each time seeing new things!
I feel like I can still smell it. We had so many days with a yellow sky I thought I was living on Tatooine.
now that was kewl
Wow. I'm seriously impressed. I used to download global water vapor maps for animations, but this is seriously next level. Cracking!
0:10-Off Mexico East Coast Mexico, Franklin
0:19-Off US East Coast, Gert
0:49-Off Mexico East Coast, Katia
1:15-To the right of Maria, Lee
1:30-In the Gulf of Mexico, Nate
1:58-South of Florida, Phillipe
Hope this helps!
wow u can actually see the smoke coming out of portugal during the summer fires
Namely those on day Oct 15, 2017.
This is the most beautiful visualization I've ever seen!
Wish this could be my screen saver
this was so relaxing to watch
The way that the Sahara Desert interacts with the atmosphere is interesting.
Why are hurricane winds so fast?
-----------
Because if they weren't, they'd be slowicanes...
Nico The Rabbit ok you got me xD
I dont get it
Hurricane Frances, your a hurricane, you know it
But I don’t
But we don't call them fasticanes though.
Fascinating, Mesmerizing, Sobering.
Who else thinks that this is so beautiful.
All that smoke from wildfires? And I love the lively weather interactions of the Atlantic and the Gulf. So much appears to be driven by heat from Africa pouring into the Atlantic and heading west. And the striation at the equator which I also just learned is called the Equitorial Doldrums is also very interesting to watch as the different air currents interact a a very well defined border.
the smoke in US territory is not from wildfires... it is not by chance that USA is a very polluting country which uses very polluting raw material to generate electricity (coal power generation)
Very very interesting animation.
I perform similar animations of atmospheric water vapour (only), where some events like hurricanes are visible.
But this is amazing.
It is possible to observe the fires in Portugal on day Oct 15, 2017.
It's interesting how a large-scale system like this resembles a smaller-scale one like cream dissolving into coffee.
that is amazing.
This shows darn good evidence of Lee being two separate systems from 1:09 to 1:14
1:06 proof that the first Lee and the second Lee were both separate storms
Jesus Christ... l know some heavy smokers but I didn’t think they puffed THAT much
Thought I was muted on Team Speak 3 at 2:04
Watching this stoned is amazing.
These are stunning movies of how winds blow dust, salt, and smoke across the planet!!
Terrific. I did not realize how much dust from the Sahara gets to the UK.
This is a little unusual. Normally, it blows over South America, fertilizing the Amazon.
I had to watch this video when I was in my science class and it helped a lot! Now I know more!
Thats Statisfying..
Спасибо, персонал, принесите такое хорошее шоу!
I would like to have the same modeling only now Pacific typhoons. As well the modeling is excellent.
Wow, that was amazing.
That was pretty amazing, from here the hurricanes seem like specks in the wind.
Mesmerizing! The wildfires that plagued the world this summer look like groups of cigarettes puffing away in unison. The dust off the Sahara is awe inspiring: I had no idea how much blew out to sea. Might that dust be instrumental in forming hurricanes and rain?
Thank you nasa
1:49 imagine if that was a hurricane aiming for us.
What's really fascinating was watching the wildfire smoke from the southeast United States.
fascinant
Please post a 4k version! And what about the rest of the world?
I'm guessing, but they probably don't have enough accurate data from the rest of the world to do an accurate simulation.
So this is showing that forest firers such as in the Western US affected the movement of hurricanes in the Atlantic and along the East Coast. The sudden move by Ophelia shows forest fires play a large part in hurricane movement. It was pulled towards the forest fires in Portugal.Just like Harvey took strength from the forest fire smoke drift from the Western US causing changes in the jet stream and feeding it. This is great data and shows correlations to more than just the fronts and Saraha Desert sands as hurricane makers.
Not sure that I follow the logic in this statement. There is no direct causal relationship between smoke and storm movement. All of the aerosols are moving with the large-scale winds, which also determine the movement of the hurricanes. The aerosols can affect cloud processes and can interact with incoming solar and outgoing infrared energy in ways that will cause some warming and cooling in the atmosphere in various ways, but the magnitude of this effect is small compared to other more dominant processes that determine the large-scale flow evolution.

Seriously cool. Thanks for posting, NASA Goddard!
now reupload this with the 2018 hurricanes
Africa's like "I don't feel so good" but still trying to live longer as possible
The possibilities of this #hpc brings tears
this should be a interactive game for weather nerds like me
Where can i see this animation for other parts of the world?
Woha, someone is having a bad day! Here's an internet hug! It will all be fine, Mr Sinister 718, stay strong!

This is from a simulation done a while back, based on data from 2006-2007. It was a precursor to the above visual focused on North America and the north Atlantic. The research into the mathematical models done here will eventually make its way into weather and climate forecasts.
NASA’s APOD 2017-11-27 _(»Hurricane Season Animated«)_ sent me here. Cheers!
Goddard, you just did it again
you can also see them turn into extra tropical storms some times
Im shocked at this years hurricane season, ophelia was one weird hurricane that hit ireland
This is beautiful
This is beautiful
This is very interesting, thank you.
so mesmerizing i dont know where to look
RASENGAN!!
Can I just point out that when Lee “reorganized” it was in a different location than the remnant circulation? Possibly it fed into another system, forming a different cyclone altogether? Might be best to consider these storms as Lee I and Lee II...
شكرا
Give NASA more money
Swap NASA and Military budgets!
How would you feel about taking money from NASA (and other sources) and giving it to NOAA? I think it would be interesting to learn more about the oceans we could one day visit, than the stars we could never reach in a million lifetimes.
What are the pulses of smoke in the Southeast US? It’s interesting because I also looked at a weather map which shows wind patterns for the entire year of 12017, and there are these pulses too!
over 50 years,
despite being tried to meet out the solution for problem
that too
through globally integrated efforts
success
sounds to be running faster than the efforts to catch it!
I would love to see a version in 4K 2160p.
Why are there daily pulses of smoke from the south-eastern area of the US, especially towards the end of the video? Is it smoke form industrial sources?
Probably. You can even identify the weekends- two days in every group of seven with nearly no emission.
Really? The forest fires just go to sleep at night?
James Frank - they are from forest fires... there is no factory that could produce anything near the volume of smoke needed to show up on this model. As for the pulsing, that may be due to the data this was based on not seeing the smoke at night or any number of other factors, but it's definitely not man made.
That was amazing.
Очень интересная информация.
we need one of those video maps daily
I'm confused as to which is *measured data* and which is *simulation.*
We run our simulations off a foundation of measured data.
no kidding...
Can u see Tropical storm Emily, Hurricane Franklin, Gert, Katia, Lee, Nate and Tropical storm Phillipe?
would be interesting if it also included the rest of the world, particularly India, China and sub-Saharan Africa
Ohh, that's why after a hurricane, every thing tastes so salty. Makes sense👌
That was awesome
I want this for other parts of the world too...
Whats with the little puffs of smoke over the south east around 1 min? A bunch of control burns? Never had wildfires this year that far south
I wonder too! They seem to occur each afternoon, judging by the date stamps at the bottom left of the video. Great examples in mid-October.
They're likely refineries or industrial sources.
That music was way too cutesy and baby-wipe-commercial for something as awesome/terrifying as our ever-warming planet.
in case you've ever wondered why it rains so much in the UK! Here's your answer.
I wish the stimulation speed was slowed down.
You can go into settings on the video (click the little gear thing) and select 1/2 speed or 1/4 speed.
1:57 ow my eyes
Wow thats amazing
yes!
What are those smokes of the southern U.S., appearing repeatedly once a day?
Damn this is cool!
theres alot of these storms that you guys dont say antything about that seem to be rotating?
So the smoke is actual smoke? produced by forest fires or human activities?
Bernard Bruinsma Almost all of it is wild fires, I'm sure a small amount of it may be human related though
So west Canada is constantly burning?
jendrekk This year, yep. I l live just south of the border in WA, and at one point our air quality was worse than Beijing. This in a city that literally has the cleanest air in the Lower 48.
Larson Stalder I'm in Seattle, literally woke up a few mornings to the kitchen having a layer of ash from an open window
The smoke was so thick most of the summer you couldn't see 10 feet down the street. Alberta had some but B.C got it the worst this year. Last year was really bad for fire season too.
awesome
Doesn't this data seem to indicate that dust from the Sahara is actually causing hurricanes? Well, among other things. But if we get some good desalination facilities to get water to the Sahara, we could decrease hurricanes, couldn't we?
Can't believe how much sand comes off the dessert!
Read about "calima" wind on Tenerife and other Canary Islands. www.teneriffa.ferienhaus-canarias.net/tenerife-holiday/tenerife-weather-calima-r239.html
and the dust was carried to estonia too
Thats A new thing to me :D
Anyone find Lee "running away from" Maria at 1:18 ?
Global modeling and ASSIMILATION office?! Is the whole office staffed by Borgs?
Data assimilation in a model means feeding the model with measured data in real time, and possibly modifying the model as a response to the data that flows in. I guess that these images were produced from a model simulation, feeded with the real data observed this summer. This is troubling because these are not the true colors, but still very very cool.
If we reclaimed the west coast of Africa and planted a bunch of trees, would it slow the wind down enough to lessen the effect of Atlantic hurricanes?
Even if sufficient numbers of trees could be successfully grown, it would not do much. Hurricanes spin up over the Atlantic Ocean, so a little increased friction at the surface over West Africa would have little impact. Over West Africa, the disturbances that lead to hurricanes usually have their maximum winds at middle levels (about 5 km above ground), and that circulation would not feel any influence of the surface friction. Stronger winds at the surface do not begin until well after the storm has moved out over the ocean.

Thanks for the detailed reply, Scott!
There's a cyclical release of "smoke" in the american southeast - what is that from?
It seems to happen mid-day, every day. Also, it happens in waves across the entire country from east to west. From what I could make out, this "smoke" is rising from more densely populated ares.
Although I don't know how they're tracking the "smoke"; I would assume it's either from mass vehicle transport or large production facilities. Or both.
Whoa. Just rewatched focusing on the southeast US. That is weird. I'd expect it more in the northeast but I guess the winds keep it in check?
The Heartbreak Time Machine wildfires
am i the only one witnessing the other big hurricanes to hit the uk?
beside ophelia
You can see the portuguese wildfires all over the year.
Damm nature you scary. Imagine sailing in the middle of the ocean and one of those hurricanes comes at you.
Are aerosols harmless to human beings and other living organisms ??
An aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas.[1] Aerosols can be natural or anthropogenic. Examples of natural aerosols are fog, dust, forest exudates and geyser steam. Examples of anthropogenic aerosols are haze, particulate air pollutants and smoke.[1] The liquid or solid particles have diameter mostly smaller than 1 μm or so; larger particles with a significant settling speed make the mixture a suspension, but the distinction is not clear-cut. In general conversation, aerosol usually refers to an aerosol spray that delivers a consumer product from a can or similar container. Other technological applications of aerosols include dispersal of pesticides, medical treatment of respiratory illnesses, and combustion technology.[2] Diseases can also spread by means of small droplets in the breath, also called aerosols.[3]
In short - It depends.

these 3 in particular... over the past quarter milllion years... i'd say not.
Salt is fine. Smoke and Sand is harmful.
Also you can clearly see chem trail aerosols being dispersed regularly through the video. Look at the American south east. Watch the continual puffs of "smoke". I DARE you to look for it.

Yes & HAARP IN ALASKA... WEATHER IS MAN-U-FACT-URED TO CONTROL THE HUMAN SLAVES.
is there an interactive version of this?
What's going on there in Canada?
