Condensation and frost on the inside of windows occur when warm, humid air inside comes in contact with a pane of glass chilled by the outside air, according to the American Society of Home Inspectors. This reduces the temperature of the air in contact with the glass, forcing condensation of moisture. If the outside temperature is cold enough, this moisture can freeze on the glass and create interior frost.Know More
A number of factors can contribute to window frost. Single-pane glass or poorly insulated windows can allow interior heat to escape, chilling the interior surface of the glass panes. High humidity levels in the home can allow extra moisture to condense on these cold surfaces, contributing to window frost.
Removing excess moisture with exhaust fans or a dehumidifier can help reduce interior frost, as can keeping blinds or curtains open and allowing air to circulate across the surface of the glass. This prevents the air at the window from becoming too cold, thus reducing the chance of condensation and frost. Increasing the heat inside the home can also help dry out the air as well as keeping warm air circulating against the windows, which prevents the glass from becoming cold enough to form frost.Learn more about Weather & Tides
Most fog forms as a result of the combination of moisture in the air and an influx of cool air that causes the moisture to fall below its dew point and condense. Meteorologists consider fog to be a type of a cloud that forms just above the ground.Full Answer >
Rainbows occur when sunlight is refracted by water droplets. From the ground, a person only sees part of a rainbow. In reality, a rainbow is in the form of a complete circle rather than the arc most people are accustomed to.Full Answer >
Deep water currents are caused by denser, colder water sinking to the bottom of the ocean while warmer, shallow water rises towards the surface. This is known as thermohaline circulation, while the continuous movement of deep water currents in the world's oceans is called the Global Conveyor Belt.Full Answer >
Low barometric pressure is caused by warm air from the planet's surface rising, decreasing the amount of air pulled downward by Earth's gravity. This rising heat can lead to adverse weather conditions.Full Answer >
