Severe Weather Foldable Design Thunderstorms Form from warm temperatures, moisture, and rising air Three-stage life cycle 1. Cumulus Stage – dominated by cloud formation and updrafts 2. Mature Stage – heavy winds, rain, and lightning 3. Dissipation Stage – updrafts stop, winds die down, lightning ceases, and precipitation weakens Tornadoes A violent, whirling column of air in contact with the ground Formation – thunderstorm updrafts begin to rotate Classification – Fujita Scale – F0 to F5 Hurricanes An intense tropical storm with winds exceeding 119 km/hr Formation 1. Warm moist air rises, Water vapor condenses, Clouds form 2. As air continues to rise, a tropical depression forms – 37 to 62 km/hr 3. Air continues to rise, Storm builds, Tropical storm forms – 62 to 119 km/hr 4. When winds exceed 119 km/hr, the storm becomes a hurricane Blizzard A violent winter storm characterized by freezing temperatures, strong winds, and blowing snow Usually form when an air mass of cold, dry, Canadian air moves south and interacts with a warm, moist air mass moving north from the Gulf of Mexico
