00:00Hello everyone, my name is Ayush Nayan and I am from IIT Delhi Center for Atmospheric Science

00:07and I am a student of first year of IIT Delhi.

00:09And we want to show some of these things that are around us,

00:14but a general person is probably not able to see it.

00:19But we are the scientists, how we interpret them, how we see, how we understand them.

00:23We are trying to explain them in a very basic way.

00:28So now as we are here, if we start with the ocean,

00:33then ocean is the ocean, the ocean basin,

00:38and how it is connected to our continent, our land,

00:43where we live.

00:45And the atmosphere above it is the atmosphere, the wayu mandal,

00:48and above it is our space.

00:50So now what happens, as you will see here,

00:55we have created the ocean basin,

01:00the ocean basin.

01:02So there are many features here.

01:04For example, you can see here,

01:06there is a small guet form.

01:09Now the truth is,

01:11that the ocean surface, the land,

01:16there is a land,

01:17you will hear,

01:18there is a land somewhere,

01:19or something happens.

01:20So what happens,

01:21our land always moves.

01:22Somewhere,

01:23it moves on a fluid,

01:25so that there are many changes in the basin.

01:28So those changes are seen on our surface.

01:31So this is the ocean basin,

01:32where there is guet.

01:33Okay, if there are volcanoes formed,

01:35or volcanoes formed,

01:37it has been removed,

01:38so it is seen in guets.

01:40It is seen in guets.

01:41So in guets,

01:42it is seen in guets.

01:43Then, as we have mountains,

01:45which we have seen here,

01:46in the basin basin,

01:47which we have seen in the basin basin,

01:48which we call sea mounts.

01:49Okay?

01:50If we call sea mounts,

01:51we call sea mounts,

01:52then we come from there,

01:53to our continental shelf.

01:55So these are the things,

01:56which we call sea mounts.

01:57Then, we come from there,

01:58then we go from there,

01:59to our continental shelf,

02:01okay?

02:02So these things are,

02:04their average depth is on the surface,

02:06on the surface around 4-5 km.

02:09From the surface,

02:10on the sea surface,

02:11around 4-5 km.

02:12Then, what happens is,

02:14that you can see mooring here.

02:16This mooring is on the basin,

02:18which is on the surface,

02:21and there are many instruments,

02:23so that we can take the readings on the beach

02:27after the mooning, the surface of the surface

02:31the air is the readings, like the wind

02:35if there is a sudden change in wind, temperature

02:39if there is a salinity, we can measure it

02:43after that, we come here, this is our

02:47ocean basin, our land

02:49so here is a continental slope

02:51then shelf

02:53if you can understand it, it is a beach

02:57and then our land

02:59okay, we are showing you

03:01now we have talked about

03:03how we measure the ocean

03:05and the ocean below

03:07or how we measure the atmosphere

03:09or how we measure the ocean

03:11or how we measure the atmosphere

03:13how we measure the air

03:15and how we measure the air

03:17now we are coming up

03:19a little above

03:21the atmosphere

03:23where the clouds are

03:25there

03:27this type of instruments

03:29we call radio zone

03:31so radio zone is what is

03:33in India

03:35many airports

03:37at least 2 times

03:39the balloon

03:41simply for example

03:43there is a lot of instruments

03:45there is a parachute

03:47and there is a lot of instruments

03:49which is left from every place

03:51basically, it is left from every airport

03:53and if you are in the water

03:55you can also leave it from the ship

03:57it goes up

03:59where it takes water

04:01where it measures its height

04:03it goes up

04:05after that, the parachute

04:07takes it down

04:09you can collect the entire atmosphere

04:11from this

04:13after that

04:14you will come

04:15to the satellite

04:16which is in the atmosphere

04:17which is in the atmosphere

04:18in our space

04:19now the satellite

04:20there are multiple kinds

04:21like geostationary

04:22polar orbiting

04:23such as geostationary

04:24polar orbiting

04:25we are saying

04:26this is a simple

04:27polar orbiting satellite

04:28for example

04:29this is a satellite

04:30which travels from one place

04:31from the other place

04:32from the other place

04:33okay

04:34so now

04:35the satellite

04:36which is in the same place

04:37the reach of the place

04:38will hit the space

04:40so it will be

04:41the same sort of data

04:42and it will increase

04:44and it will increase

04:45so that

04:46so this will be

04:47many many times

04:48earth-luckers

04:50and the same way

04:51he will collect the entire earth

04:52and it can be very

04:53false data

04:54now

04:55why did we all do this

04:56all?

04:57our work

04:58is that

04:59this is what happens

05:00it is instruments

05:01after that

05:02If you want to use the poster, this is the poster in which there is a lot of data that has been created and has been collected on the server.

05:12Now, what do we need to use the server?

05:17There are a lot of servers that are stored there.

05:21Then, the scientists will process the data.

05:25For example, if we have data from satellites,

05:28we can make many images like the aerosol optical depth.

05:32How much pollution is there?

05:33How much pollution is there?

05:34How much pollution is there?

05:35We can measure the wind.

05:37How much direction is there?

05:39We can measure the wind.

05:41There are altimeters.

05:42If you have seen the bathymetry,

05:44where is the mountain?

05:45Where is the ocean?

05:47What is the ocean?

05:49How does the surface look at the space?

05:51We can measure that.

05:53After that, the data comes from radio.

05:55Now, there is a very basic figure.

05:57So, these scientists know how many images have come from?

06:03How many lines intersecting?

06:05They can predict what the weather will be.

06:07Whether it will be thunderstorms,

06:09or buaisers,

06:10whether there is pleasant weather,

06:12the weather may be.

06:14Then, we can measure the radio from the radio.

06:16We can measure the boys.

06:18Boys and drifters,

06:18and it's also such as many names.

06:20Some properties of their boats are separate.

06:23to for example if you can see our Indian Ocean Bay of Bengal and Arabian Sea and this

06:29way we call our Omni Buies, Ramah Buies, the different type of institute which we keep

06:40from America and India partnership and many different ways that all instruments are placed

06:48the data we can see in the graph form or different colourful graphs

06:56in the form. For example, I have a small example. For example, recently a cyclone

07:01came out. If a cyclone has any region in any region, the cyclone is in the ocean

07:07in the ocean. If there is a buoy in its past, the cyclone has formed

07:13to make it from there, the changes of the alguien, the sea, the sea, the sea, the sea

07:20and the sea, the sea, the sea, the sea, the sea, the sea, the sea and the sea

07:25and the sea. After that, we understand that, from this cyclone or from this particular

07:30thing, what the difference between our life is in our lives, how can we do it and

07:36learn and forecast it. These are very basic instruments, very different types of instruments

07:42we have different types of data but this is a basic thing so that we observe our atmosphere

07:49and our ocean
