THROUGHOUT HISTORY, humankind has always been in awe of the weather. Ancient civilizations considered it to be the work of the gods. Even as recently as the 1700s, it was thought that weather occurred in only 1 place and simply stayed put. Benjamin Franklin was 1 of the first who published his speculations that this was untrue when he learned that a storm he experienced in Philadelphia, Pennsylvania, was followed by a suspiciously similar 1 in Boston, Massachusetts the next night. In the years that followed, forecasts continued to be based on folk knowledge as well as emerging science, such as the observations of courageous balloonists who went aloft in search of approaching storms. With the progression of technology, instruments were sent aloft instead. Today, satellites do much of the work of watching weather patterns. Weather information- sharing takes place on a global level. Many countries’ weather forecasts incorporate data gathered by U.S. satellites, which are shared with the entire world—even during times of disagreement. Weather plays a big part in our daily lives. It affects many of the things that we do, from the clothes we wear and the food we eat to where we live and how we travel. As a result, weather is of great interest to people everywhere, from meteorologists, the scientists who study it in great depth, to ordinary citizens pursuing everyday lives. A safe topic of polite conversation is always the weather, particularly in areas where the weather is changeable and unpredictable. The cowboy philosopher Will Rogers once commented about the constantly changing weather in his native Oklahoma: “If you don’t like the weather, wait 10 minutes.” Such change is not exclusive to Oklahoma. Hawaiian rental car operators chuckle at the familiar site of newly arrived tourists driving away from the airport only to stop suddenly and jump out of the car to snap photos of a rainbow. The newcomers do not realize that Hawaii’s weather can vary on opposite sides of the street—with sunshine on 1 curb and rain on the other, and lots of resulting rainbows.
