About This Chapter

Let us show you about various weather conditions and their causes. In these videos and texts you'll see how tornadoes, hurricanes and thunderstorms form, and learn about how hurricanes can be predicted.

Weather Conditions & Severe Weather Phenomena - Chapter Summary

In this chapter's lessons you'll explore the causes of important dimensions of the weather such as air pressure and temperature. Our expert instructors will explain how the atmosphere circulates, and describe weather fronts. Other lessons look at specific weather events and their causes, including thunderstorms, cyclones and hurricanes. After watching these lessons, you should be prepared to:

  • Discuss atmospheric variables how they influence weather
  • Explain atmospheric circulation
  • Name types of weather fronts and their effects
  • Define causes of weather events including tornadoes, hurricanes, thunderstorms and cyclones
  • Describe how hurricanes are forecast
  • Examine causes and types of floods along with preventive measures
