How Does the Wind Blow?
Wind cannot move by itself. It takes the Sun to get it going. Because of Earth’s shape and rotation, the Sun does not heat our plant evenly. This leaves some part of Earth, such as the North and South poles, cold. Other areas, near the equator for example, are hot.
Earth’s different temperatures cause the atmosphere to be different from place to place. The differences in the air pressure cause the air to move from side to side across the land and water. Wind is what we call this moving air.
How exactly does the wind blow? Think of it as a dance between warm and cold air molecules…

The Wind Blew ME Away!
As I began researching about the wind, this every day phenomena blew me away from the start.
I became so fascinated in the wind that all I could do for days (and weeks) is read books, books, and more books, and journal articles, and research documents, and interview meteorologists, and blow around in the wind with my niece, Olivia, to learn as much as I could.
Now, that I know a lot about the wind, I want to know more. I guess that’s what learning does to you. The more you know, the more you want to know. Learning also changes you.
I don’t think I'll ever look at or think about the wind in the same way ever again. I hope that when you read my windy book, you will feel differently about the wind, too.
“Chapters are kept short, and they include follow-up questions that check readers’ comprehension
...Beautiful, full-color, captioned photos appear on nearly every page, breaking up the text and offering visual context...tailor-made for young report writers.”
"Each title has five chapters of short sentences with easy vocabulary and a review question with a one-word answer. Interesting color photos and an activity are included."
--School Library Journal, December 2006
"If you need science material to support a standards-based inquiry science program, look no further."
--Library Media Connection, April/May 2007
"What a delightful book! HOW DOES THE WIND BLOW? fulfills a real need for a very well-written children's book about the types, causes, and reasons for the winds of the earth. I highly recommend it for school libraries everywhere."
--Harry Volkman, Retired TV meteorologist and Chicago legend, Chicago, IL
“HOW DOES THE WIND BLOW presents the complicated subject about the hows and whys of wind in an easy-to-understand manner.”
--Dennis Cain, Meteorologist, National Weather Service, Austin, TX
"Wind is 'air that is in motion,' and its most important job is to bring us weather, this nonfiction 32-page book in the "Tell Me Why, Tell Me How" series explains. One of the five chapters touches on the types of winds including the Chinook wind, California's Santa Ana wind, the north wind, the west wind, the polar easterlies, the westerlies, and the northeast and southeast trade winds. Author Patricia Murphy does a good job of providing definitions for wind-related terms such as air pressure, jet stream, hurricanes, and tornadoes. The book also provides a description of both the anemometer and the wind vane and how they work. And, of course, the answer to the book's title question: "Wind blows because the earth is unevenly heated by the sun." In the back of the book, there is a manageable classroom activity: building a wind vane. A curious student reader with an interest in science would gain inspiration and ideas from this book."
