What causes humidity to rise?

Answer 1

The idea is that the greenhouse effect, caused by excessive waste gases in the atmosphere, trap heat on the earth and are therefore rising the temperature of the Earth. This causes the ice caps to melt, and ice is frozen water, so it melts into the sea. Of course, since there is an increasing amount of water in the sea, the sea rose, and it continues to do so right now.

Answer 2

1) Change the amount of water vapor available; if there is liquid

water present, for instance, a lake, you can have an increase in

relative humidity by evaporation from the surface of the lake. This is

pretty obvious. You're adding water vapor, so the humidity increases.

2) The other way is to change the temperature of the air, while

holding the water vapor constant. Even though there is no water

source, and no water vapor is added, a lowering of air temperature

results in a rise of relative humidity. This is automatic. The amount

of water vapor that could be present at saturation is less at the

lower temperature, so the existing amount of water vapor represents a

higher percentage of the saturation level of the air. Similarly, a

rise in temperature results in a decrease in relative humidity, even

though no water vapor has been taken away.

Key point to remember: Given that the amount of water vapor is held

constant, then if you

--reduce the temperature, the relative humidity goes up

--increase the temperature, the relative humidity goes down.?

3) At a given temperature, the quantity of water vapor is inversely proportional to changes in pressure: falling pressure will increase the moisture content.?

Answer 3

Low air temperature will cause water vapor to condense and rise. This also causes the water vapor to become visible.
