Question 2

Which of the following best describes tornado development?
 
  A) Evaporation over warm ocean waters leads to convective thunderstorms; as laten energy is released as the water vapor condenses, tornadic activity is spawned.
  B) A horizontally rotating body of air is tipped vertically by an updraft with a cumulonimbus cloud, forming a mesocyclone, which can generate tornado activity.
  C) Strong downdrafts in a cumulonimbus cloud cause the formation of funnel clouds, which pulse from the bottom sometimes forming tornadoes.
  D) Orographic uplift near warm ocean currents forces warm, moist air to rise and cool to dew point. The latent heat associated with condensation leads to strong downdrafts and tornado formation.
  E) Bands of rapidly moving thunderstorms create powerful, straightline winds.
