About This Chapter
Precipitation - Chapter Summary and Learning Objectives
Explore various types of precipitation and how they're formed with the lessons in this chapter. Also, find out how worldwide precipitation is related to winds and pressure patterns. By the end of this chapter, you should be able to:
- Differentiate among convection, orographic uplift and frontal uplift.
- Explain how to measure rain and snow.
- Describe the processes of runoff and infiltration.
- Identify reasons for cloud seeding.
|What is Precipitation? - Definitions, Types & Formation||Describe how precipitation forms, and identify different forms of precipitation, including rain, snow, sleet and glaze, hail and rime.|
|Causes of Precipitation: Convection, Orographic Uplift & Frontal Uplift||Identify and describe various causes of precipitation.|
|Identifying & Describing Precipitation Processes||Identify and describe precipitation processes, including growth by condensation, growth in warm clouds (collision and coalescence) and growth in cool and cold clouds (Bergeron process and riming and aggregation).|
|Global Precipitation Distribution & Its Relationship to Global Winds and Pressure Patterns||Describe and explain how global precipitation is related to global winds and pressure patterns.|
|Measuring Precipitation Using Rain Gauges & Snow Measurement||Describe how precipitation is measured (rain gauges and snow measurement).|
|Runoff & Infiltration: Definition & Process||Describe what happens to precipitation after it falls to land.|
|Cloud Seeding & the Consequences of Cloud Seeding Experiments||Describe cloud seeding, and debate the efficacy and consequences of cloud seeding experiments.|
1. 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.
2. Runoff & Infiltration: Definition & Process
When water falls to the ground as precipitation, it can either fill the spaces in the soil below ground or run across the surface. In this video lesson, you will learn about the processes of infiltration and runoff, and how they are an important part of the water cycle on Earth.
3. Causes of Precipitation: Convection, Orographic Uplift & Frontal Uplift
Discover what precipitation is and learn about what causes it. Understand and visualize how air masses are affected by changes in temperature and topographical features to produce precipitation.
4. 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.
5. Global Precipitation Distribution's Relation to Wind & Pressure Patterns
The water cycle of evaporation, condensation, and precipitation isn't the only thing that determines if it will rain or not. In this lesson, we'll look at the effects of wind and pressure patterns on rainfall around the world.
6. Measuring Precipitation Using Rain Gauges & Snow Measurement
From old men sitting around playing checkers to suburban dads wanting to water their yards, it seems everyone talks about rain and snow fall. But how do we really know how much of either has fallen? This lesson explains how.
7. The Efficacy & Consequences of Cloud Seeding
Can we make rain? And not in a test tube either. Can we, like mighty Zeus, force nature to give us rain? Find out in this lesson as we go over the concept of cloud seeding.
