ya, now we will talk about lightning, a atmospheric discharge.

I actually wrote about the lightning, because in Indonesia itself should have been summer, but until now the rain had happened almost every day of the week. sometimes the rain was also accompanied by lightning. makes me think of lightning itself

when we see lightning in the sky, the feeling of awe and nervous, we always feel it.
but do we know how lightning can be created? actually I also do not know. but if we learn a bit from now, maybe we can slowly begin to understand the nature where we stand.
this article I got from wikipedia, of course. I would be great if I could write an article like this myself.



Lightning


Lightning is an atmospheric discharge of electricity accompanied by thunder, which typically occurs during thunderstorms, and sometimes during volcanic eruptions or dust storms. In the atmospheric electrical discharge, a leader of a bolt of lightning can travel at speeds of 60,000 m/s (130,000 mph), and can reach temperatures approaching 30,000 °C (54,000 °F), hot enough to fuse silica sand into glass channels known as fulgurites which are normally hollow and can extend some distance into the ground. There are some 16 million lightning storms in the world every year.

Lightning can also occur within the ash clouds from volcanic eruptions, or can be caused by violent forest fires which generate sufficient dust to create a static charge.

Lightning can initially be formed by condensed water in clouds freezing into hail, then being blown by wind. The wind smashes the hail together, separating positive and negative charges. When enough negative charges build up, lightning is formed and strikes the tallest object near it.[citation needed]

How lightning initially forms is still a matter of debate: Scientists have studied root causes ranging from atmospheric perturbations (wind, humidity, friction, and atmospheric pressure) to the impact of solar wind and accumulation of charged solar particles.Ice inside a cloud is thought to be a key element in lightning development, and may cause a forcible separation of positive and negative charges within the cloud, thus assisting in the formation of lightning.

The irrational fear of lightning (and thunder) is astraphobia. The study or science of lightning is called fulminology, and someone who studies lightning is referred to as a fulminologist.

ok, this is explanation of lightning in the Indonesian language :

Petir

Petir atau halilintar adalah gejala alam yang biasanya muncul pada musim hujan di mana di langit muncul kilatan cahaya sesaat yang menyilaukan biasanya disebut kilat yang beberapa saat kemudian disusul dengan suara menggelegar sering disebut Guruh. Perbedaan waktu kemunculan ini disebabkan adanya perbedaan antara kecepatan suara dan kecepatan cahaya.

Petir merupakan gejala alam yang bisa kita analogikan dengan sebuah kapasitor raksasa, dimana lempeng pertama adalah awan (bisa lempeng negatif atau lempeng positif) dan lempeng kedua adalah bumi (dianggap netral). Seperti yang sudah diketahui kapasitor adalah sebuah komponen pasif pada rangkaian listrik yang bisa menyimpan energi sesaat (energy storage). Petir juga dapat terjadi dari awan ke awan (intercloud), dimana salah satu awan bermuatan negatif dan awan lainnya bermuatan positif.

Petir terjadi karena ada perbedaan potensial antara awan dan bumi atau dengan awan lainnya. Proses terjadinya muatan pada awan karena dia bergerak terus menerus secara teratur, dan selama pergerakannya dia akan berinteraksi dengan awan lainnya sehingga muatan negatif akan berkumpul pada salah satu sisi (atas atau bawah), sedangkan muatan positif berkumpul pada sisi sebaliknya. Jika perbedaan potensial antara awan dan bumi cukup besar, maka akan terjadi pembuangan muatan negatif (elektron) dari awan ke bumi atau sebaliknya untuk mencapai kesetimbangan. Pada proses pembuangan muatan ini, media yang dilalui elektron adalah udara. Pada saat elektron mampu menembus ambang batas isolasi udara inilah terjadi ledakan suara. Petir lebih sering terjadi pada musim hujan, karena pada keadaan tersebut udara mengandung kadar air yang lebih tinggi sehingga daya isolasinya turun dan arus lebih mudah mengalir. Karena ada awan bermuatan negatif dan awan bermuatan positif, maka petir juga bisa terjadi antar awan yang berbeda muatan.


after reading a bit about lightning. now let's see are some lightning
are really difficult to find pictures of the actual lightning. mostly just a fake picture. actually I would be very happy if i could give my own picture. but it is really difficult.



Looks very real




I think this picture is really real





I doubt with this picture


OK, after seeing some pictures which may be natural, we now see pictures of lightning that might is not natural but still dazzling enjoy it :
