Why is there lightning when it rains?
1. Lightning is a natural phenomenon, usually caused by storm clouds, with negative charge at the bottom and positive charge at the top. A huge current rushed from the ground to the clouds along the conductive path, producing bright and dazzling flashes;
2. In most cases, lightning can only be generated when the thickness of lightning cloud exceeds 3 kilometers. The upper part of the cloud is usually positively charged and the bottom of the cloud is negatively charged. When the electric field between positive and negative charges is strong enough, it will break through the air and produce lightning.
3. Many scientists believe that falling raindrops or ice hockey carry negative charges, while positively charged particles, such as small dust particles and ice crystals, gather in the upper part of the cloud, making the upper part of the cloud positively charged and the lower part negatively charged, generating an electric field sufficient to trigger lightning, thus triggering lightning when it rains.
