Why doesn't it lightning on a cloudy day? I mean lightnings when there are rain clouds but normal clouds on a sunny day don't yeild lightning. Is it rainwater's conductivity?
K^2 said:Rain carries the charge between cloud and ground[b/], allowing the clouds to become charged. So yes, rain is instrumental in causing lightning.
You can have lightning without rain in some rare situations. When air is sufficiently dry and warm at low altitude, you can have rain drops that evaporate before they reach the ground. In that case, the charge is carried between two clouds, and you can see lightning between these clouds without there being any rain at ground level. But it still has to be raining up there.
Lightning is an electrical discharge caused by the buildup of static electricity in the atmosphere. When lightning strikes, it neutralizes the electrical charge in that area, making it less likely for another strike to occur in the same place. Additionally, lightning is attracted to tall objects, and once it strikes a tall object, it will usually dissipate and seek another path.
Lightning forms when warm air rises and collides with cooler air, causing a separation of charged particles. This creates an electrical charge in the atmosphere, and when it becomes strong enough, it will discharge as a lightning strike.
The color of lightning depends on the type of gas and particles in the air where the lightning occurs. For example, if there is a lot of nitrogen in the air, the lightning may appear blue or purple. If there is a lot of dust or pollution, the lightning may appear orange or red. Lightning can also appear white, which is caused by a mix of gases and particles in the air.
While we can track weather patterns and predict the likelihood of thunderstorms, it is nearly impossible to predict exactly when and where lightning will strike. Lightning can be unpredictable and can strike in unexpected places, making it difficult to accurately predict.
Yes, lightning is extremely dangerous and can cause serious damage and injury. It is estimated that lightning strikes kill around 24,000 people worldwide each year. It is important to seek shelter and stay indoors during a thunderstorm to avoid the risk of being struck by lightning.
