SEATTLE — The Q13 Information digital staff has a saying:
“There are not any silly questions… in terms of climate.”
We’ve requested the climate workforce some doozies through the years, together with our on a regular basis winter ask of “is it going to snow quickly?”
So once we questioned allowed “why is the bottom moist when it’s sunny out,” we thought we’d get an eye fixed roll.
Sure, the reply is pretty easy. Nevertheless it’s not with out nuances.
A fast Google search of the query brings again a easy phrase: Dew. Q13 Chief Meterologist Walter Kelley confirms the wettness on the concrete and within the shadows is certainly dew.
“The air cools to the dew level,” Kelley stated. “That’s the temperature through which air condenses sufficient to type dew or on this case make the bottom moist. If there’s sufficient moisture you get fog. You’ll be able to visualize ‘morning dew.’”
We’ve seen a variety of foggy mornings these days. However even when it isn’t foggy, the air continues to be cool sufficient to condense the air.
Q13 Information Meterologist M.J. McDermott says the longer we keep in a sunny, dry sample, the much less moisture we’ll see on the bottom.
“The longer the excessive strain, the drier it will get,” McDermott stated. “The dewpoint will get actually low because the environment dries out. Till there isn’t any fog, no frost, no ice, simply bone dry circumstances.”
Fog and dew get rarer in drier circumstances. With no rain within the forecast for a minimum of the subsequent seven days, we might see much less and fewer moist concrete.
