PART I ATMOSPHERIC SYSTEMS: Weather and Climate

PARTI

ATMOSPHERIC SYSTEMS: Weather and Climate

33

The Sun’s heating of Earth’s surface and water vapor in the atmosphere give rise to gentle breezes and gale-force winds, sunny afternoons and torrential downpours. Part I explores the work of solar energy and water in creating atmospheric systems, and it explores the changing climate system.

CHAPTER 1

Portrait of the Atmosphere

An envelope of gases surrounds Earth, makes weather possible, and makes Earth habitable.

CHAPTER 2

Seasons and Solar Energy

Solar energy and seasons create temperature differences and atmospheric motion.

CHAPTER 3

Water in the Atmosphere

Solar energy evaporates water into the atmosphere, forming water vapor and precipitation.

CHAPTER 4

Atmospheric Circulation and Wind Systems

The Sun’s energy drives global wind and precipitation patterns.

CHAPTER 5

THE RESTLESS SKY: Storm Systems and El Niño

Atmospheric motion organizes into different systems, from gentle sea breezes to deadly storms.

CHAPTER 6

The Changing Climate

Earth’s climate system changes naturally and from human activity.
