About This Chapter

Brush up on your knowledge of the causes of storms and severe weather. You'll learn about the circulation of the atmosphere, weather fronts and the forecasting of severe weather events.

Severe Weather & Disturbances - Chapter Summary

Use this chapter's lessons to review facts about atmospheric circulation and weather. Study variables such as temperature, and learn about the atmosphere's circulation and weather fronts. See what causes floods and how they can be prevented.

Other lessons look at the causes of storms, including tornadoes, thunderstorms, cyclones and hurricanes. After watching the lessons in this chapter on severe weather, you'll have a better understanding of the following:

  • Variables in weather, including air pressure, temperature and density
  • The circulation of the atmosphere
  • Types of fronts and their impact on weather
  • Definition and causes of tornadoes, and the Enhanced Fujita Scale
  • Types of thunderstorms and how they form
  • Causes of hurricanes and how they are forecast
  • Types of floods and their prevention

These lessons include short multiple-choice quizzes that let you assess your knowledge. Video tags make it easy to return to a spot that requires additional study and, if you have more questions, you are welcome to contact the instructor.

Weather Variables: Air Pressure, Temperature & Density

1. Weather Variables: Air Pressure, Temperature & Density

Weather is influenced by a number of factors. In this lesson, you will learn about three key variables that control weather and how they work together to do so.

The General Circulation of the Atmosphere

2. The General Circulation of the Atmosphere

The Sahara Desert, tropical rainforests, and cold polar winds are all due to Earth's rotation. In this video lesson, you will learn how this rotation has created global air circulation patterns on Earth and how it is responsible for such diverse climate patterns across the globe.

Understanding Weather Fronts: Types & Their Effect on Weather

3. Understanding Weather Fronts: Types & Their Effect on Weather

In this video lesson you will learn about how air masses with different characteristics create weather fronts. You will also identify the different types of fronts, as well as what type of weather occurs along them.

What Are Tornadoes? - Definition, Causes & The Enhanced Fujita Scale

4. What Are Tornadoes? - Definition, Causes & The Enhanced Fujita Scale

Tornadoes are dangerous storms that affect millions of people. In this video lesson, you will learn how and where they form, as well as how scientists classify tornadoes using the Enhanced Fujita Scale.

What Are Thunderstorms? - Definition, Types & Formation

5. What Are Thunderstorms? - Definition, Types & Formation

Thunderstorms are common all over the world. In this video lesson, you will learn what they are, how they form and how they create thunder and lightning.

What Are Cyclones? - Types, Causes & Effects

6. What Are Cyclones? - Types, Causes & Effects

The word cyclone refers to many different types of storms. In this video lesson you will learn about how cyclones form, what makes each type different, and what their effects are on both people and the environment.

Hurricanes: Types, Formation, Causes & Effects

7. Hurricanes: Types, Formation, Causes & Effects

Hurricanes are dangerous storms that affect millions of people each year. But what are hurricanes and how do they form? In this video lesson you'll learn about where and how hurricanes develop as well as the types of hurricanes that are possible.

Forecasting Hurricanes & Creating Advisories

8. Forecasting Hurricanes & Creating Advisories

Understand the severity of hurricanes and how they develop. Learn how scientists are able to gather data on, track, predict, and categorize hurricanes. Know how hurricane advisory systems work.

What Are Floods? - Causes, Types & Prevention

9. What Are Floods? - Causes, Types & Prevention

In this video lesson, you will study floods, their causes and their effects. You will learn to identify various methods that are used to prevent floods and explore how preventing natural flood cycles can lead to dangerous flood events.
