Description of the atmosphere in terms of wind, temperature, clouds and precipitation is called an Atmospheric condition
What measures atmospheric pressure (air pressure)? Barometer
What do you call wispy air weather clouds; rain or snow? Cirrus clouds
What do you get when a cold air mass is cutting under a warm air mass and lifting it? Cold Front
Cumulus clouds that have grown very tall; usually bringing severe storms are called Cumulonimbus clouds

Smooth gray clouds that block sunlight; can bring light rain and drizzle are called Stratus clouds
The measure of the amount of heat energy in the atmosphere is called Temperature
A storm with thunder and lightning and typically also heavy rain or hail is called a Thunderstorm
Dark funnel of strong winds that spiral upward is called a Tornado
The condition of the atmosphere at a place for a short period of time is called Weather
A map showing the state of the weather over a large area is called a Weather map
