About This Chapter
Atmospheric Conditions & Types of Weather - Chapter Summary
In this chapter, you'll find lessons that clearly explain atmospheric conditions and different types of weather. Topics presented here include a definition of weather and the effects of water's physical properties on weather processes. The process of cloud formation, including adiabatic and diabatic processes, plus the types and causes of fog are also covered. After you finish this chapter, you should be able to complete the following:
- Outline the formula and calculation used for dew point
- Discuss cloud formation, the environmental lapse rate and static stability
- Identify the types and formation of precipitation
- Detail the forming processes associated with precipitation
- Describe air pressure, density and temperature as weather variables
- Explain the vertical and horizontal movements of high and low pressure areas
- Outline the collection methods used for weather data
- Define the maps and symbols used for weather analysis
Take your time as you complete this chapter, going back to review as much as needed and taking the quizzes after the lessons to check your comprehension level. We've also provided a comprehensive test at the end of the chapter that makes a handy tool for test preparations. You can study whenever you'd like with these resources, which are accessible 24 hours a day on any computer or mobile device.
1. Weather: Definition & Types
Talk about weather is everywhere: on the news, in the papers, and in almost every conversation. What causes it all, though? In this lesson, we will define weather, take a look at the different types, and learn what causes weather changes to take place.
2. How Water's Physical Properties Affect Weather Processes
More than 70% of the earth's surface is covered by water. In this lesson, we will learn the relationship between the physical properties of water, the water cycle, and how this affects the weather we experience.
3. What is Cloud Formation? - Definition, Types & Process
There are many different types of clouds that form in the sky. In this video lesson you will learn about how clouds form, as well as the different types of clouds and how they are classified.
4. Adiabatic vs. Diabatic Processes: Cloud Formation
Why does air cool? And how is this related to cloud formation? This lesson will explore the adiabatic and diabatic processes, which are a couple of ways the air can cool, and then relate this to cloud formation.
5. What is Fog? - Definition, Types & Causes
In this lesson, we'll talk about fog - what it is and why it happens. Fog comes in many types, and here we'll cover the definition of each and how they are formed.
6. What is Dew Point? - Definition, Formula & Calculation
Learn what the dew point is and how to calculate it. Understand the characteristics of the dew point temperature and how it's a useful aspect of forecasting the weather.
7. Static Stability, Cloud Formation & The Environmental Lapse Rate
Here, we explore how the static stability of air in the atmosphere influences the vertical movement of air's likelihood of cloud formation. At the end, you can test your knowledge with a brief quiz.
8. What is Precipitation? - Definition, Types & Formation
Precipitation comes in many forms, but it all comes from the same general process. In this video lesson you will identify different types of precipitation, as well as how precipitation forms in the atmosphere from condensation.
9. Precipitation Forming Processes
In this lesson, you will learn how water molecules turn into precipitation. Also, you will discover how varying conditions can lead to different types of precipitation.
10. 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.
11. High & Low Pressure Areas: Horizontal & Vertical Movements
Weather is part of our daily lives. In this lesson, we will explore what causes stormy weather, dry weather, and the general movement of air called wind.
12. Weather Data Collection Methods
Learn how we collect weather data, which we can then use to make forecasts. Learn about the devices we use and where we place them. See how well you understand how to collect data by taking a quiz.
13. Symbols & Maps Used to Analyze Weather
In this lesson, you'll find out why we analyze the weather and learn the symbols we use to represent every possible weather condition. We'll talk about the station model, surface weather maps, and other air charts. See how well you work with symbols by taking a quiz.
