Answer:
A storm is categorized into different stages as its wind speed and air pressure change. The changes in wind speed and air pressure are used to determine the storm's intensity and classification. The most commonly used classification system for storms is the Saffir-Simpson Hurricane Wind Scale, which categorizes hurricanes based on their sustained wind speeds. Other storm classification systems may be used for different types of storms, such as tornadoes or thunderstorms. Regardless of the classification system used, the changes in wind speed and air pressure are key indicators of a storm's development and intensity.
