PDF-ir always contains a certain amount of water in the air in the form of water vapour

This amount of moisture is commonly known as the humidity The capacity of the air to hold water vapour increases with the temperature This is why in our homes as soon as the temperature decreases the vapour contained in the air condenses as is evide. This is commonly known as humidity This determines the level of humidity in an atmosphere The capacity of the air to hold water vapour increases with temperature This is why in our homes as soon as the temperature decreases the vapour contained in t The . sole responsibility for the content of this publication lies with the authors.

Water in the atmosphere – in all its phases. Last week, we focussed on the weather systems found in the mid-latitudes.. The heart of the mid-latitudes is the polar front, where warm, tropical air from the south meets cold, polar air from the north.. Vapour Pressure. , . Relative Humidity . and . Dew point temperature. .. . The partial pressure in air due to water vapour alone is called “vapour pressure”.. . It is expressed in energy units viz., millibar or millimetre of mercury..
