Microscopic particles on which water vapor condenses to form cloud droplets.
a wispy white cloud (usually of fine ice crystals) at a high altitude.
What you can predict when you see a cirrus cloud
Long, thin cirrus clouds with curved ends
A rainbow colored spot of light that forms when sunlight refracts off of six sided ice crystals in cirrus clouds
A narrow column of light at sunset.
The traditional fair weather cloud.
Air in a cumulus cloud is...
A rounded bottom
The most common mistake in drawing a cumulus cloud
dry adiabatic lapse rate
1 degree per 100 meters
wet adiabatic lapse rate
5 degrees per 1000 meters
the weight of the atmosphere above an object
Light shining down from a cloud (think light from heaven)
Rain that evaporates before hitting the ground
Clouds that layer over most or all of the sky
What does a uniform color in a stratus cloud indicate?
When cumulus clouds layer the sky
Prefix that means "higher than usual"
prefix that means "actively precipitating"
The general term for the amount of water vapor in the air.
The process whereby water vapor changes its form to a liquid state.
the energy stored or released during a phase change.
The conversion of a solid directly to a gas.
The process by which a solid changes phases into a liquid.
The temperature to which the air would have to be cooled to reach saturation.
when the environmental lapse rate is greater than the dry adiabatic rate
when the environmental lapse rate is less than the wet adiabatic rate
unit of heat defined as the quantity of heat required to raise the temperature of 1 gram of water by 1 degree centigrade at atmospheric pressure
form of condensation best described as a dense concentration of suspended water droplets, or tiny ice crystals
the process of changing from a gaseous to a liquid state
the occurrence of two or more things coming together
dew point temp
when air is cooled to reach saturation
the process by which water changes from liquid form to a gas
when water is below 0 degrees celsius and still in liquid state
when a cold front pulls in and warm raindrops condense to liquid state into the cool air
when cold air is over warm water
on clear nights Earth's surface cools rapidly and the moisture in the air contact fog below its dew point
warm air on cool surface
when air is moving on a gradually sloping mountain, making the air expand and cool adiabatically
