The more water evaporates in a given area, the more water vapor rises into the air, and the higher the humidity of that area is. Hot places tend to be more humid than cool places because heat causes water to evaporate faster. It might sound like water evaporation is a bad thing. Liquid water is useful, plus, you know, essential for all life. Believe it or not, though, water evaporation and humidity serve a critical function of the natural world.
When liquid water evaporates into gaseous water vapor, it has completed one third of the all-important water cycle. When water vapor rises, water molecules in the vapor combine with each other and with other particles like dust, salt, and smoke.
The higher the water vapor rises, the thinner the air around it becomes. When temperatures cool down, the water particles in clouds condense into their liquid form and fall as rain.
There are a couple different means of calculating humidity in both absolute and relative terms. Without water vapour, we would not be able to live on Earth. As a greenhouse gas, water vapour lets energy from the Sun pass through and warm the Earth.
The Earth then radiates energy away, but some of this energy is trapped on the way out by greenhouse gases adding extra warmth. The average temperature of the Earth at the surface is Water vapour is important for moving energy around the Earth. Energy from the Sun evaporates water into water vapour, which can easily be moved around the atmosphere. The water vapour eventually condenses back into water releasing energy as heat.
This heat is a key component in the formation of storms. Humidity is essentially the amount of water vapour in the air, so if air has a lot of moisture in it, and it's a warm day, it will feel very close and muggy, making it difficult for us to keep cool. Relative humidity adjusts its percentage for that. When it comes to home comfort, relative humidity is most important.
You want to adjust for temperature when determining how much moisture is in the air. If the humidity in your home goes outside these guidelines, you could run into some problems. This affects home comfort and can even cause some health issues. It depends on just how humid it is. For starters, all that moisture can end up costing you extra money in energy bills.
The more humidity, the harder your system works to heat your home. Elsewhere, slightly high humidity can cause mugginess. This can make people in the house feel a little hot or generally uncomfortable. As the humidity climbs higher, you may notice condensation on your walls or in your window panes.
A smart thermostat can help you assess the air in your home to understand humidity levels. And if you are having challenges getting in the 30 to 50 percent range for humidity, there are humidifiers and dehumidifiers that offer a solution for getting to the right amount of humidity. If you see any of the warning signs listed above, or if you want an expert to come out and review the humidity in your home, Air Temperature Control can help.
