Question

why does the humidity affect the weather?

Answer 1

The amount of water vapor in the air varies from trace amounts to about 4 percent of all atmospheric gases, depending on a variety of factors. The percentage of water vapor—or humidity—determines how you feel when you are outside, as well as the health of the animals and plants around you. It also determines the formation of clouds and the probability of a weather event, such as a thunderstorm or crippling winter blizzard.
