About This Chapter
Atmospheric, Weather & Wind Patterns - Chapter Summary
So many factors have an impact on weather! These fun, informative video lessons explain how air and pressure circulate in the atmosphere, the effects of weather fronts, and how features on the surface of the Earth can have a major impact on climate. Video transcripts make it easy to locate key vocabulary terms, and students can submit weather questions to our instructors for additional help.

1. Atmospheric Circulation: Scale & Observation
Atmospheric circulation is responsible for the weather you experience. This lesson will explain how atmospheric circulation works and then it will explore how it impacts the weather in a couple of different locations.
2. The Single-Cell Model of General Circulation
Have you ever wondered how air circulates in the atmosphere? This lesson will explain an early model of air circulation, the single-cell model. It will also look at some of the problems with this early model of air circulation.
3. The Effects of Semi-Permanent Pressure Cells
Although semi-permanent pressure cells don't sound particularly exciting, they actually are. This lesson will describe how pressure systems develop and examine four semi-permanent pressure cells.
4. 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.
5. 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.
6. 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.
7. Rossby Waves & Cyclonic Activity
Chances are you've never heard of a Rossby wave, but these waves are important players in the weather patterns you observe on a daily basis. This lesson will explore Rossby waves and then we'll explain how Rossby waves are related to cyclones.
8. 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.
9. Air Conditions of Different Types of Wind
Winds are all the same, right? Actually no. This lesson will examine different types of wind including the Chinook, a type of foehn wind, and the Santa Ana winds, a type of katabatic wind.
10. Air Conditions of Different Types of Breezes
Breezes are light winds, but did you know there are different types of breezes? This lesson will examine sea, land, valley and mountain breezes, explaining how they form and where you can find them.
11. 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.
12. El Niño, La Niña & Walker Circulation
This lesson will explore how the Walker Circulation works, as well as El Niño and La Niña. It will include how these weather patterns impact weather patterns around the world.
13. 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.
14. Arctic Oscillation & North Atlantic Oscillation
You've probably never thought much about the Arctic Oscillation or the North Atlantic Oscillation, but these weather phenomena impact global climates. This lesson explores each oscillation and describes the weather patterns associated with them.
15. 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.
16. How Continents & Oceans Influence Global Pressure Distribution
The movement of air in Earth's atmosphere is driven by several variables, including differences in pressure. Here we will examine how the presence of land and ocean affect differences in pressure, followed by a brief quiz to test your knowledge.
17. Oceanic & General Atmospheric Circulation
The movement of air and water across the planet is the driving force of climate and weather patterns. There are many factors that affect ocean and atmospheric circulation, and here we will explore what they are and how they function. At the end, you can test your knowledge with a brief quiz.
