How is air pressure usually measured?
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.
What time of day is wind the slowest?
The early night is the time from about 10 pm to 2 am. Typically, temperatures will continue to cool off during this time frame. This is a time where the atmosphere will often reset from being less stable to much more stable. The wind speeds tend to be lighter due to less mixing of air and stable air.
Why is there no wind 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.
What is the coldest hour of the day?

Resulting in it being the warmest time of the year.
