Welcome to Low-Pressure Area, a podcast from Campbell Scientific that explores the weather around us and the environmental measurements that help us understand it. Each episode tackles the questions people really have about the weather, climate, and meteorological phenomena shaping our everyday lives. In episode 4 we explore precipitation in its many forms; how we define precipitation, where the word comes from, why there are so many sub-categories (including one called diamond dust) and how you can even have precipitation that falls from a cloud but never reaches the ground.
