Lightning flashes ....:Find out what is lightning with 100 million to 1 billion volts of energy that kills thousands of people every year and why it falls to earth





Temperatures around 10,000 degrees Celsius to 30,000 degrees Celsius rise in the area where lightning strikes.
138,00,000 times in India in 2019-20, 185,44,367 times in the year 2020-21
Lightning strikes the earth's surface about 100 times per second



At least 70 people were killed in a series of lightning strikes last Sunday in the country's three largest states of Uttar Pradesh, Madhya Pradesh and Rajasthan.




During April 1, 2019 and March 31, 2020, natural disasters i.e. lightning killed 1771 people in the country, in addition to April 1, 2020 and March 31, 2021, 1,619 people died. People have always wondered why lightning strikes the sky with thunder in the rain and why it often falls to the ground. Today we will talk about natural phenomenon electricity.





Why lightning strikes and why it falls to the ground

When the clouds in the sky collide with each other, they get an electrical charge, then the negatively charged particles pick up in each other's direction. In these circumstances an electrical field is prepared. The electricity generated by friction often falls to the ground in search of a conductor.
In other words, "thunder cloud" is created by generating electricity in extreme heat and humidity conditions, which takes the form of storms. It creates a negative charge on the lower surface of the cloud and a positive charge on the upper surface at an altitude of 8-10 km above the Earth's surface.




 Discharge lightning flashes when the distance between the two is greatly reduced. In these circumstances the condition of thunder and lightning is seen.
But when lightning strikes the ground in search of a conductor it can do a lot of damage. It stays on the ground for as long as a millisecond.

How much energy-temperature is contained in electricity

Lightning strikes the earth's surface about 100 times per second. Its power is also extraordinary and contains millions of volts of energy.
Lightning has an energy of about 100 million to 1 billion volts. Wherever it falls, the ambient temperature rises from 10,000 degrees Celsius to 30,000 degrees Celsius.
Such high levels of energy and temperature are extremely destructive. The temperature of electricity is about the same as the surface of the sun.

What happens when lightning strikes the ground

As soon as electricity reaches the earth, it finds a medium through which it can pass easily. In these circumstances electricity comes in contact with iron poles or high places which act as conductors for it.
If a human comes in contact with it at that time, it acts as a conductor for electricity. Generally, the risk of lightning at noon is increased.
The risk of lightning strikes increases when a tree is sheltered, especially when lightning strikes. Also called "side flash". In India, a quarter of lightning deaths are caused by people living under or standing under trees.
According to research, out of the total number of deaths due to lightning, 78 per cent are due to standing under tall trees and 22 per cent are due to open ground.

The Brahmaputra valley in eastern India has the highest electricity generation

Northeast India usually has a high risk of lightning during a storm called Kalvaishakhi. In Bihar, Jharkhand, Chhattisgarh and Uttar Pradesh, the incidence of lightning is higher during the pre-monsoon hali.

According to NASA, the Brahmaputra valley in eastern India receives the highest amount of lightning in the world on an average every month.
However, Venezuela's Lake Maracaibo is listed in the Guinness Book of World Records as having the most electricity. Electricity is generated 250 times per kilometer every year.
On the other hand, according to the annual report on electricity for the year 2020-21, the rate of electricity generation in the country has increased by 34 per cent. In the year 2019-20, India had 138,00,000 times electricity, which has increased to 185,44,367 in the year 2020-21. Odisha, Madhya Pradesh, Chhattisgarh and West Bengal have the highest number of lightning strikes.

The
Climate Resilient Observing Systems Promotion Council (CROPC) has entered into a Memorandum of Understanding (MOU) with the Indian Meteorological Department (IMD), Ministry of Earth Sciences (MoES), Government of India, including Satellite. Observations, network of Doppler and other radars, lightning detection sensors and other devices can be used to make accurate predictions. In addition, scientists from IITM, IMD also use the holistic prediction tool.

What can be done to reduce the risk of lightning

Lighting conductors should be made mandatory in tall buildings.
Keep a certain distance from power generating equipment like phones, radiators, metal pipes etc.
Stay indoors when the clouds are roaring
Do not take shelter under an open field or tree when lightning strikes, and stay under a tall building.
