    WASHINGTON (DC News Now) — Lately, we’ve been seen a rollercoaster of weather across the DMV. Some days temperatures are cold and other days the temperature is warm. Sometimes we see lots of flooding and other days we see no rain. But how does this affect the weather?

    WASHINGTON (DC News Now) — Now that fall is in the DMV leaves will continue to change across the area. But what is the science behind the leaves changing?

    WASHINGTON (DC News Now) — During the day, the sun heats the earth’s surface, and heat is released back into the atmosphere at night in a process called radiational cooling. According to the National Weather Service, traditional cooling is “the cooling of the Earth’s surface.”The Earth suffers a net heat loss to space at night due to terrestrial cooling, which is more pronounced when the sky is clear. Radiational cooling is greater when we see clear skies and light winds across an area.
