Puffy,lumpy looking clouds that occur below 2000m
What are cumulus clouds?
Air rises because of unequal heating of Earth's surface within one air mass causing
What is an air mass thunderstorm?
The amount of water vapor in the atmosphere at a given location on Earth's surface.
What is humidity
An instrument used to measure the direction of the wind.
What is a wind vane?
Layer closest to Earth's surface.
What is the troposphere?
Wispy indistinct appearance
What is cirrus?
a violent and oppressive wind blowing in summer, especially in Sudan, bringing sand from the desert.
What is a haboob?
Occurs when the amount of water vapor in the air has reached the maximum amount.
What is saturation?
Instrument used to measure air pressure.
What is a barometer?
A layer in which the air temperature mainly increases with altitude and contains the ozone layer.
What is the stratosphere?
All forms of water that fall from clouds to the ground are called this.
What is precipitation?
Self sustaining extremely powerful storms
What are supercells?
The amount of water vapor in a volume of air relative to the amount of water vapor needed for that volume of air to reach saturation.
What is relative humidity?
This measures wind speed.
What is an anemometer?
The layer between about 85km to 600km above Earth's surface. Low density of air.
What is the thermosphere?
Layered sheet like clouds. Forms when fog lifts from Earth's surface
What is stratus?
A violent whirling column of air in contact with the ground.
What is a tornado?
The temperature to which air must be cooled at constant pressure to reach saturation.
What is the dew point?
An instrument that measures humidity.
What is a hygrometer?
The air temperature decreases with altitude in this layer which is above the stratopause.
What is the mesosphere?
When an air mass is forced to rise over a topographic barrier.
What is orographic lifting?
The scale used to measure tornado damage
What is the Fujita tornado damage scale
Extra thermal energy contained in water vapor compared to liquid water.
What is latent heat?
Measures rain fall over a length of time.
What is a rain gauge?
Outermost layer of Earth's atmosphere.
What is the exosphere?
