Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water.
So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.

What causes barometric pressure?
Barometric pressure measures the weight of the air.
What causes increases in barometric pressures?
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
What happens when barometric pressure increases?
When the barometric pressure rises it means calm fair weather is coming or is already occurring. When the barometric pressure falls it means foul weather is on the way such as rain and storms and clouds.
What is Moisture condensed from the atmosphere?
Barometric pressure is not affected by moisture in the Earth's atmosphere
Is barometric pressure the same as atmosheric pressure?
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.
What causes barometric pressure?

The center of a hurricane is characterized by very low what?
A hurricane has very low barometric pressure.
What is Moisture condensed from the atmosphere?
Barometric pressure is not affected by moisture in the Earth's atmosphere
Does barometric pressure go up or down in tornadoes?
Barometric pressure goes down in a tornado.
What does sudden decreases in barometric pressure indicate?
A sudden decrease in barometric pressure is a sign that a storm is coming.
Is barometric pressure the same as atmosheric pressure?
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.
What is barometric pressure sensor?
A barometric pressure sensor is a type of sensor located within an engine system. It helps retain proper fuel mixtures at different altitude using barometric pressure measurements.
Sentence with the word barometric in it?
As the weather was changing, the barometric pressure continued to rise.
What is Air pressure on a station model?
the barometric pressure
