1. Why do Single-Cell Thunderstorms dissipate fairly quickly? a. Because the Unstable Lapse Rate no longer exists b. Because the airmass isn't humid enough to support continued growth c. Answer: Because the precipitation-induced Downdrafts cut off the Updrafts d. Because the initial Lifting Action s...
1. Why do Single-Cell Thunderstorms dissipate fairly quickly? a. Because the Unstable Lapse Rate no longer exists b. Because the airmass isn't humid enough to support continued growth c. Answer: Because the precipitation-induced Downdrafts cut off the Updrafts d. Because the initial Lifting Action stops 2. How does a Thunderstorm form large Hail? a. Cyclonic action forces the hail stones to combine through centrifugal force. b. Answer: Strong downdrafts in the storm accelerate the speed of the hail towards the Earth, allowing the hail to grow through collision and coalescence. c. Answer: Strong updrafts keep the hail suspended in the storm while it continues to grow through collision and coalescence. d. Lightning causes the hail stones to combine through electromagnetic forces. 3. When does the Mature Stage of a Thunderstorm begin? a. When Thunder begins b. When the Storm consists entirely of Updrafts c. When Lightning begins d. Answer: When precipitation contacts the Earth's Surface Why do Squall Line Thunderstorms form? a. High Pressure causes a large-scale Lifting Action and clockwise rotation. b. Answer: Lifting Action is produced by a Front that can run for hundreds of miles. c. Wind pushes the storms further away from the initial source of Lifting Action. d. Low Pressure causes a large-scale Lifting Action and counter-clockwise rotation. How does a Supercell thunderstorm, that can grow extremely Large and last for many hours, differ from a Single Cell Thunderstorm? a. The Supercell is produced from Multicell storms, rather that being a single, isolated cell. b. Answer: The Supercell has a tilted vertical structure that separates the updrafts from the downdrafts. c. Supercell storms produce thunder and lighting, while Single Cell storms do not. d. Supercell storms do NOT require an initial source of Lifting Action, while Single Cell storms do.
