Humidity and Dew Point

______________is the general term used to describe the amount of water vapor in the air.

Which of the following are terms that meteorologists use to express the water content of the air:

• Relative humidity
• Dew point temperature
• Temperature
• Precipitation
• Cloud cover

________________ is equal to the actual water content divided by the capacity of water the air can hold.

Relative humidity is:

• the measure of how close the air is to being saturated
• the temperature at which air saturation has been reached
• the altitude at which air saturation has been reached
• the temperature of the air based on the wind speed
• the temperature of the air based on water content
