Learn about the relationships among the Sun, clouds, and weather in this video excerpt from NOVA's Cloud Lab. The Sun heats Earth's surface unevenly, driving global weather patterns that carry heat and humidity around the world. Differences in air pressure result in wind, causing air masses with different temperature and humidity to move. Clouds and powerful storms can form at a frontal boundary, where two air masses meet. For example, the uplift of warm, humid air over cold, dense air can create strong thunderstorms. Studying atmospheric conditions on a large scale can help forecast local and regional weather as well as the global climate.
