What is thunder?

Lightning or lightning is the phenomenon of atmospheric discharges between clouds and the ground or between clouds bearing other charges, sometimes appearing in volcanic eruptions or dust storms (sand). When discharging in a lightning atmosphere, it can travel at 36,000 km / h.

Lightning is the movement of ions but the image of lightning is generated by the plasma flow, so it can be seen before hearing the noise because the noise only moves at 1,230 km / h under normal conditions. of air and light travel 299,792,458 m / s.

Lightning can reach a temperature of 30,000 ° C, 20 times the temperature needed to turn silica sand into glass.

Lightning is the movement of ions but the image of lightning is generated by the glowing plasma flow.

What causes the phenomenon of thunder?

When two charged charged clouds are close together, the voltage between them can reach millions of volts. Between the clouds there is a phenomenon of sparks and we see a lightning bolt. A few seconds later we hear the explosion, it is thunder (because the speed of light is faster than the speed of the sound so we see the previous lightning). When the charged thundercloud cloud approached the ground to empty areas, met an object with height like trees, shovel pickers . there would be a phenomenon of sparks between the cloud and the ground. That is the phenomenon of thunder.

1. When staying indoors, stand away from windows, doors, electrical appliances, avoid damp areas such as bathrooms, water tanks, faucets, do not use the phone unless absolutely necessary.
2. It is advisable to unplug electrical equipment before any thunderstorms occur. With telephone lines or wires because of connecting to external grids, it is very likely to be affected by lightning spread.
3. Keep away from these wires and electrical objects with a distance of at least 1 meter. The antenna must be removed from the television when there are thunderstorms.
   
   If outdoors, absolutely do not use trees to shelter rain, avoid higher areas around, away from metal objects such as bicycles, machines, iron fences .
