How do satellite infrared images help meteorologists?

Infrared imagery shows the heat radiated by cloud tops, so the colder the top, the higher the cloud and typically the stronger the convection underneath. This makes IR a powerful tool for gauging storm intensity and ongoing convection, especially when visible data aren’t available (like at night or through thick clouds). That's why infrared images are used to infer how vigorous a storm is when you can’t rely on visible light. Surface wind speeds aren’t directly measured by infrared, it doesn’t just detect fog, and it doesn’t directly monitor precipitation rates—the main utility is linking cloud-top temperatures to convection strength and storm vigor.
