Show Does Dew Fall? DEW DOES now fall. However, dew is an interesting weather element and close observation of it can tell you . something about the weather to follow during the day. Dew collects on surface objects, ob-jects, like blades of grass, and is moisture taken from passing, pas-sing, warmer air. THE EARTH objects which collect it from the air must be colder than the air so as to condense some of the moisture out of the surrounding air. Seeing dew, either at night or early morning, is a clear weather indication though not a foolproof one. THE ABSENCE of dew tells you that chances are good that rainfall is ahead sometimes in the next 24 hours. |
