The Frederick Carder Pre-K class was featured in this week’s Weather Wisdom.
Gabriella asked the question, “where does rain come from?”
Rain is a part of the water cycle. Of course, other weather factors come into play. Think of a low pressure system, which creates forms of precipitation. Temperatures then determine which type of precipitation we will see. Groundwater evaporates, rises up into the atmosphere, then cools and condenses to form clouds. Precipitation falls usually through cold air to start. We see rain then form as that precipitation falls through a warm layer of temperatures above freezing. When we have colder air aloft and warmer air at the surface, that is when we see sleet or freezing rain form. Of course, when temperatures stay at freezing or below from the surface up, that is when snow is formed.
