Preface

Like the serendipitous traveler in Robert Frost's The Road Not Taken, we decided to follow a path "less traveled by" in writing this introductory guide through meteorology. Sometimes, the broadening experience of travel is limited by taking a traditional tour. We have written this book with the aim that students do not merely go sight-seeing along the superhighway of meteorology. Rather, we hope that students become real travelers, willing to detour off the beaten path and to actively seek new adventures that will broaden their appreciation and understanding of how the atmosphere works.

The Blizzard of 1993. Hurricane Andrew. The Great Flood of 1993. These mighty forces of nature awakened the awe of weather in many people. Students who bring a sense of wonder about weather to an introductory course expect to study such events -- but not in a passive way. Henry David Thoreau once wrote: "The traveler must be born again on the road, and earn a passport from the elements". Throughout A World of Weather, students will earn their passport from the elements by working with historical weather data, affording them opportunities to unravel the back-road secrets of some of the greatest storms on earth. It is this "hands-on" approach that makes students active travelers rather than passive tourists on the road to learning meteorology.

A World of Weather is a text book. It is also a laboratory manual. Real-life examples and non-traditional problems, as well as a hands-on approach, make our book a valuable teaching tool for introductory courses at both large and small universities, including colleges that do not have a meteorology program and offer only one course in weather. Though the text is streamlined for college students with a non-meteorology major, we firmly believe that A World of Weather will also serve as a well-rounded foundation for students intending to major in meteorology.

Fundamentally, we want students to be good weather consumers. They will be bombarded by all types of weather information throughout their lives. Some of it will be scientifically accurate; some of it will be fuzzy and misleading. For example, the notion that the heat index represents "the temperature the air feels like" is not meteorologically or physiologically sound. Humans do not all "feel" the same. Moreover, the heat index is based solely on temperature and humidity, and does not take other factors into account. But it's undeniable that cooling summer breezes sometimes. Yet the heat index neglects the cooling power of the wind. Thus, any attempt to quantify exactly what "the air feels like" becomes a bit futile. Students who use A World of Weather as a guide through meteorology will be aware of such pitfalls. They will learn that wind-chill values are not based on human physiology but on how fast it once took water in plastic bags to freeze under varying wind conditions in Antarctica.

Like Robert Frost's traveler who came upon two roads diverging in a wood, we believe that, by choosing A World of Weather, you have taken "the one less traveled by." And it will make all the difference.
