Ch 11: Weather Disturbances

About This Chapter

Watch online video lessons about weather disturbances. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of cyclones, thunderstorms, tornadoes and more.

Weather Disturbances - Chapter Summary and Learning Objectives

If you've ever wondered what causes a superstorm or even how thunderstorms in general form, this chapter on weather disturbances could provide the answers you're looking for. You'll learn how hurricanes are forecast and how the Enhanced Fujuta Scale is used to rate the intensity of tornadoes while likely encountering some weather terminology you haven't come across before, like 'haboob' (a type of dust storm) and 'derecho' (a form of wind storm).

By the end of this chapter, you should be able to:

  • Describe the formation of various types of weather disturbances, including cyclones, tornadoes and hurricanes.
  • Distinguish among the cumulus, mature and dissipative stages of the air mass thunderstorm cycle.
  • Discuss different types of lightning.
  • Differentiate between hurricane watches and warnings.
