Weather refers to the conditions in the atmosphere at any given time and place, including temperature, humidity, wind speed, and precipitation. This dynamic environment is influenced by a variety of factors, such as the sun’s energy, the rotation of Earth, and its surface features, including mountains, oceans, and forests. And yet, despite scientific advancements and sophisticated forecasting tools, the local weather that impacts people’s daily lives continues to remain a mystery to many.
Gain a better understanding of what weather is and how it works with meteorologist Edward Graham as he surveys the core science behind the operation of Earth's weather and climate systems. After an introduction to the planet’s atmosphere, Graham explains air pressure and how it drives the movement of air from place to place. He explores the formation of air masses, their often-stormy interaction with one another, and why weather systems tend to spin in a particular direction. He also discusses how Earth is monitored daily and how millions of weather observations are gathered to make the weather forecast for tomorrow. Graham is an atmospheric scientist based at the University of the Highlands and Islands in Scotland.
