Ch 22: Air Masses & Wind

About This Chapter

You'll get an in-depth look at various air mass types while you're watching this chapter's fun video lessons. Major factors that have an impact on wind are discussed in these brief videos.

Air Masses & Wind - Chapter Summary

This chapter's videos make sure you are familiar with El Nino and La Nina, including their effects on land and at sea. You can learn about the Pacific Decadal Oscillation in one of the engaging lessons and study polar fronts and gradient forces. By watching the lessons in this chapter, you'll also be brushing up on these relevant topics:

  • The names of the major wind belts
  • The causes of jet streams
  • Types of monsoonal circulations
  • Gradient forces, Coriolis Effect and other factors that affect wind

Refresh your knowledge of wind and air masses by watching these videos on a computer or your Internet-enabled handheld device. Once you complete any of these videos, you can go back to double-check any of the main segments with the video tags. Every lesson comes with a practice quiz that enables you to quickly confirm your grasp of the material.

The Global Wind Patterns of the Three Wind Belts

1. The Global Wind Patterns of the Three Wind Belts

You are familiar with wind, but did you know there are different wind belts depending on where you are on the earth? This lesson will examine the three main wind belts: polar easterlies, tropical easterlies and prevailing westerlies.

Jet Streams & the Polar Front

2. Jet Streams & the Polar Front

You've probably heard about jet streams during the news weather segment. But what is a jet stream? This lesson will explain how jet streams form, what they are and then will focus on the polar jet stream.

Monsoons & Monsoonal Circulations

3. Monsoons & Monsoonal Circulations

Monsoons bring a seasonal change in weather to many parts of the world. This lesson will explore two monsoonal circulations and will also discuss how monsoons impact the people who experience them.

Factors That Affect Wind: Pressure Gradient Forces, Coriolis Effect & Friction

4. Factors That Affect Wind: Pressure Gradient Forces, Coriolis Effect & Friction

In this video lesson, you will learn about wind and some factors that affect it, such as air temperature and pressure, the Coriolis effect, and friction. By the end of this lesson, you will also understand how Earth's rotation plays a role in how winds travel.

The Relationship Between El Nino & La Nina

5. The Relationship Between El Nino & La Nina

In this video lesson, you will learn about El Niño and La Niña. You will understand the differences between them, as well as some of their effects on both ocean waters and weather patterns on land.

The Pacific Decadal Oscillation & El Nino

6. The Pacific Decadal Oscillation & El Nino

Understanding the Pacific Decadal Oscillation, or the PDO, and El Niño allows scientists to better understand weather phenomenon. This lesson explores the PDO, as well as its similarities with El Niño and La Niña.

Types of Air Masses & Their Effect on Weather

7. Types of Air Masses & Their Effect on Weather

Air masses affect weather in a number of different ways. In this lesson, you will learn about the different types of air masses found on Earth and how the movement of air masses creates changes in the weather.
