00:00Yes, but very rarely do you feel the thundering of the clouds.
00:03It may be raining heavily outside,
00:05but you don't see lightning or thunder in the clouds.
00:10There can be many reasons for this.
00:12Or you may see lightning,
00:15or you may see clouds in the thundering rain,
00:17but the thundering of lightning is very uncommon here.
00:22It is also very rare in the world,
00:23especially if we talk about Pakistan.
00:25But for the past few days,
00:27in Tharparkar district,
00:29there have been many reports of lightning.
00:31In one month,
00:33more than 30 times,
00:35there have been reports of lightning.
00:37200 people. It's a huge number.
00:39It's a huge number.
00:41And I would say that we don't talk about it that much.
00:43In our country,
00:45it is obvious that we talk about other issues.
00:47But the thundering of lightning
00:49is happening here as well.
00:51There are similar incidents in India as well.
00:53There are similar incidents all over the world.
00:55There are many reasons for it.
00:57And how can we avoid it?
00:59It is obvious that lightning speed,
01:01when a thunderbolt hits you,
01:03there are chances of you not being able to avoid it.
01:05But you know,
01:07many people say that
01:09don't go out in the rain,
01:11stay away from iron structures.
01:13Stay away from trees,
01:15especially when we hide there.
01:17If you see your hair standing up,
01:19or if you feel it,
01:21stay away from it.
01:23Let's talk about this.
01:25We have Dr. Riaz Uddin with us.
01:27Associate Professor, Electrical Engineering Department.
01:29Thank you so much, Dr. Riaz, for joining us.
01:31First of all, tell us,
01:33in which stories have we heard about this?
01:35But the incidents that have been reported
01:37from Tharparkar,
01:39is this a new phenomenon because of climate change?
01:41Thank you, Sadaf,
01:43and thank you, Ishfaq.
01:45Actually, this is very unfortunate.
01:47And really,
01:49my condolences to the families.
01:51This is basically because of climate change.
01:53And this is not a new phenomenon.
01:55If I share some statistics with you,
01:57for example, in the United States,
01:59every year,
02:01there is an average lightning
02:03of about 25 crores.
02:05And there are about 70,000
02:07insurance claims,
02:09in which 2 billion US dollars,
02:11which is about 6 billion Pakistani rupees,
02:13are claimed.
02:15So this is a very common phenomenon,
02:17which we think is obvious.
02:19But unfortunately,
02:21due to some reasons,
02:23climate change is happening very fast.
02:25And unfortunately,
02:27we are in a situation
02:29where all these things happen.
02:31So before this,
02:33we have to understand
02:35how lightning and thunders
02:37actually occur.
02:39When it gets very hot,
02:41and due to climate change,
02:43the moisture of the air
02:45goes up towards the upper atmosphere.
02:47And due to the lower temperature,
02:49the moisture of the air
02:51comes to the freezing temperature,
02:53i.e., ice bubbles form.
02:55And they separate themselves
02:57in the lighter and heavier parts.
02:59Due to the air,
03:01they get ionized.
03:03As you must have seen,
03:05if you rub any plastic,
03:07it basically creates an attraction.
03:09As soon as it starts floating in the air,
03:11heavy charged molecules,
03:13because the earth is a very good
03:15And as the size of the cloud increases,
03:17where there are open spaces,
03:19like the area of Dharpar,
03:21people have less awareness
03:23to avoid these things.
03:25So the thunder falls down.
03:27There are three types.
03:29There is thunder in the clouds,
03:31which you can see in the clouds,
03:33but it doesn't fall down.
03:35And in the third case,
03:37where there is a very large size,
03:39where there is good conduction,
03:41there is thunder.
03:43Probably,
03:45there is no special reason for it.
03:47Just because of the reporting.
03:49Because it is a very common phenomenon.
03:51If you go overall,
03:53as I told you,
03:55in Texas alone,
03:57there are about 408 claims
03:59of $48 million insurance.
04:01People can claim there.
04:03Here, the system is also there.
04:05It can be made,
04:07but I am just telling you the number.
04:09I was watching
04:11when you were saying
04:13that 25 crore strikes are only there
04:15and 1.4 billion strikes are worldwide.
04:17I wanted to know
04:19that the way it strikes now,
04:21most of the strikes are
04:23on airlines and aircrafts.
04:25But obviously,
04:27because they know
04:29how to manage it
04:31and how to release it in the air,
04:33their planes get damaged
04:35and there is no catastrophe.
04:37What else can be done
04:39in these areas?
04:41Do you know,
04:43there are lightning arresters
04:45and lightning rods.
04:47They are grounded
04:49and it is a proper protection system.
04:51You install it
04:53through electric cords
04:55and the lightning strikes
04:57at a higher level
04:59and all the lightning is arrested
05:01and a proper ground is provided.
05:03What can be done in these areas?
05:05There are some suitable points
05:07where humans and animals
05:09are good conductors of electricity.
05:11There is a lot of livestock
05:13and that could be the reason.
05:15As far as I know,
05:17Tharparkar's economy
05:19is based on livestock.
05:21We have to go to the university campus
05:23and we have seen that
05:25there are a lot of livestock
05:27at one place.
05:29It is good for lightning.
05:31That is why people
05:33don't allow it near trees
05:35and if you are a tall person
05:37and a good conductor of electricity,
05:39the example of lightning
05:41is like the water of electricity.
05:43If it finds a big path,
05:45it will go from there.
05:47You provide a way for it.
05:49There are some suitable places
05:51or platforms
05:53where you can install
05:55livestock or humans
05:57at one place.
05:59This can be one of the ways.
06:01There is no specific reason
06:03that you are in this area
06:05just because of unawareness.
06:07Thank you so much.
06:09Dr. Ria, I hope
06:11many people got the information.
