Hurricanes and Severe Weather Concepts

The video tutorial covers severe weather phenomena, focusing on thunderstorms, tornadoes, and hurricanes. It explains how these weather events form, their characteristics, and their impacts. Thunderstorms are common near the equator and involve warm, humid air rising to form clouds and precipitation. Tornadoes are violent wind storms with a rotating air column, often forming from thunderstorms. Hurricanes, also known as tropical cyclones, require warm water to form and have distinct parts like the eye and eye wall. The Saffir-Simpson scale classifies hurricanes by intensity, and they lose energy when moving over land or cooler waters.

What is the primary factor that contributes to severe weather?
