Why is it typically windy during the day but not so much at night?
In: Earth Science
Must be a local thing where you are, possibly because you are a long way from the sea, here in Ireland it is now gone ten PM and where I am the wind is blowing a hooley.
Because of the sun: it warms the earth up so there is a difference in temperature: cool air (more dense than warm air) at ground level, warm air (less dense than cold air) higher up. And that triggers air moving.
The sun heats up the air, which causes density differences, which causes sinking and falling air. Then you get wind.
During the day when it’s warm. The warm air will rise up into the atmosphere. This leaves behind an area of lower air pressure on the ground, and air will move to equalise that pressure. Sort of like when you have high pressure air inside of a balloon and you let go of the tip. The air rushes out of the balloon to equalise the pressure inside and outside of it.
Why do people ask ELI5 questions that you can literally get an ELI5 as the top search of Google?
