• Cirrus cloud
• Cumulus cloud
• fog
• Stratus cloud

temperature at which water vapor condenses out of the air

• fog

• humidity

cloud that forms just above the ground surface

precipitation that falls as rain but freezes on contact with cold surfaces near the ground, forming a glaze of ice

• freezing rain
• hail
• snow
• rainice

precipitation that falls as balls of ice and forms when strong updrafts carry rain high into the troposphere, where the rain freezes

measure of what the temperature feels like because of humidity

• relative humidity

amount of water vapor in the air

• humidity

percent of water vapor in the air relative to the maximum amount the air can hold

• relative humidity
• humidity
• heat index
• warm front

 precipitation that falls as small ice pellets and forms when snow melts as it falls through a layer of warm air and then refreezes as it passes through a layer of cold air near the ground
