How Does Lightning Form? Safety Rules During a Thunderstorm
How electricity builds up in clouds, how to estimate how far a strike is, and what to do and avoid in a thunderstorm.
Why This Guide Matters
Step-by-step Implementation:
How clouds build up electricity
Inside a thundercloud, ice particles and water droplets rub against each other as they move up and down. Positive charge gathers near the top and negative near the bottom. When the difference becomes large enough, current discharges through the air as lightning.
How far away is the strike
Light arrives almost instantly, but sound travels about 340 metres per second. Count the seconds between the flash and the thunder and divide by 3 to get the distance in kilometres.
What to do in a storm
Shelter inside a solid building or a car. Wait at least 30 minutes after the last thunder before going out. Stay away from plugged-in appliances and water taps.
If you are stuck outdoors
Crouch low with your feet together and head down, but do not lie flat. This reduces the risk from current spreading through the ground. It is a last resort; look for safe shelter first.
