Why is it more windy at night?
The layer of fluid in contact with an underlying surface is called the boundary layer. The atmospheric boundary layer moves through a daily cycle based on heat from the sun. This cycle of daytime heating and nighttime cooling explains why, under most circumstances,
higher winds are confined above the surface at night
.
Why is wind gusty?
Friction, atmospheric pressure and air warming
can all play a part in sudden bursts of wind. Gusts are sudden but short-lived increases in the speed of the wind. They’re often created as wind brushes past buildings, trees or other obstacles, with the friction causing it to slow and then speed up again.
Why does the wind drop at night?
The wind speed tends to decrease after sunset because
at night the surface of the Earth cools much more rapidly than does the air above the surface
. As a result of this difference in cooling ability, it doesn’t take long for the ground to become colder than the air above it.
