15: Thunderstorm Hazards

  • Page ID
  • The basics of thunderstorms were covered in the previous chapter. Here we cover thunderstorm hazards:

    • hail and heavy rain,
    • downbursts and gust fronts,
    • lightning and thunder
    • tornadoes and mesocyclones.

    Two other hazards were covered in the previous chapter: turbulence and vigorous updrafts.

    In spite of their danger, thunderstorms can also produce the large-diameter rain drops that enable beautiful rainbows (Fig. 15.1).
