The Science of Rain .

Everyone loves rain. But sometimes rain feels like a game,  it can be a light drizzle or a heavy downpour. This depends on the size and spread of clouds. The speed of wind also plays a role. To know how much water is in rain clouds, weather scientists use a tool called a coppler. Using this, they can predict light or heavy rain. Clouds are made of water vapor. At first, tiny vapor particles form. As they cool down, they become water droplets. When these droplets grow heavier, they fall to the ground as rain. Sometimes, the droplets evaporate before reaching the ground. As long as wind is strong, clouds and droplets stay in the sky. When the droplets become too big, they fall as heavy rain. Rain falls at a speed of 30 km/hour. Small clouds bring light showers, while big dark clouds (called cumulonimbus) bring heavy rainfall. It is estimated that one inch of rain on one acre of land weighs about 118 tons! On average, the Earth receives 32 inches of rain per year.

You’ll be amazed to know that lightning is constantly happening somewhere in the world or in space. Even while you’re reading this, lightning is flashing somewhere on Earth. In fact, around 100 lightning flashes happen every second worldwide!
