Water vapour is water in it's gaseous state, also known as steam. This is created when water is heated above 100 degrees Celsius and evaporates. What is evaporated is water vapour.
In weather, this condenses in the atmosphere, which is generally cooler than the surface of earth, to form clouds. When water vapour condenses, droplets join together and eventually become a denser state - liquid. When the clouds become too dense to remain suspended in the atmosphere, they fall to Earth as rain.
That is the effect of water vapour in our atmosphere.

When liquid water passes into the gaseous state, the process is called vapourisation of water-the particle is called water vapour.Atmospheric air always contains a small quantity of water in the form of invisible vapour called water vapour.The water vapour mixed with air behaves like any other gas.So it also contributes its own pressure to the total pressure of the atmosphere.Moreover the proportion of water vapour to air is also constantly changing.

Water vapor(also vapour) is the gas phase of water. It is water in the form of a gas, produced by evaporation.

Water vapour comes from the Evaporation /sublimation of water or ice its made from water molecules that have heated up and risen above the water /ice surface

As you can see from the answers you're getting, the exact nature of your quesion is not clear.
However, since you've posted it in the Weather category, I'm guessing that you are asking what significance water vapor levels have on weather conditions.
High water vapor levels in the troposphere indicate humid conditions and a higher likelyhood of rainfall. Weather satellites gather water vapor information using radar and infared cameras.

Water vapor, also aqueous vapor, is the gas phase of water. Water vapor is one state of the water cycle within the hydrosphere. Water vapor can be produced from the evaporation of liquid water or from the sublimation of ice. Under normal atmospheric conditions, water vapor is continuously evaporating and condensing.
