👉 Rainbands are a type of precipitation that forms in the atmosphere when water vapor reaches liquid or gas state. They occur when warm, moist air rises and cools rapidly due to the condensation process, creating tiny droplets or ice crystals. Rainbands can form over land or on the ocean surface, and they can be observed as streaks or streams of raindrops falling from the sky. Rainbands are often associated with thunderstorms because they produce a loud and distinctive noise when they form.
