What is a rainbands?

Rainbands are elongated regions of precipitation that spiral outward from the center of a storm, particularly in tropical cyclones like hurricanes. They are typically associated with thunderstorms and can produce heavy rain, strong winds, and severe weather. Rainbands can extend hundreds of miles from the storm's eye and are crucial in determining the storm's overall impact on surrounding areas. Their formation is driven by the storm's rotation and atmospheric conditions.
