  1. Mechanical
  2. Convective
  3. Frontal
  4. Orographic (Mountain Wave)

9. Thunderstorms: Three criteria that must be met for the formation of a cumulonimbus (thunderstorm) cloud:

  2. Convection, unstable air (steep lapse rate), dry air
  3. Lifting agent, stable air (shallow lapse rate), moisture
  4. Lifting agent, unstable air (steep lapse rate), moisture

10. Radar: The type of precipitation weather radar (ground based or aircraft) can detect with the highest accuracy:

  1. Rain
  2. Snow
  3. Ice crystals
  4. Wet snow

11. Fog: The type of fog that forms when warm moist air advects over a cool surface is:

  1. Convection fog
  2. Steam fog
  3. Advection fog
