Atmosphere
The percent of oxygen in the air.
What is 21%
This is how winds are named.
One knot equals this.
What is 1.15 miles
Clouds, fog, snow, and rain are created when water vapor changes to liquid.
What is condensation
A huge body of air usually 1,000 miles across or more that has the same temperature and moisture characteristics.
What is an air mass
The layers of the atmosphere in order starting from the lowest to the highest.
What is troposphere, stratosphere, mesosphere, thermosphere
What are prevailing westerlies
This has average wind speeds of 120-150 mph, it's important to consider for flight plans, and it moves further south in the winter.
What is the jet stream
The continuous movement of water between the Earth and its atmosphere.
What is the water cycle
Name the front:
1. cold air comes in
2. warm air comes in
3. warm and cold air comes in but neither moves
What is:
1. Cold front
2. Warm front
3. Stationary front
What is 350 miles
This causes object to move to the right in the atmosphere in the Northern Hemisphere.
What is the Coriolis Effect
A downdraft of air that diverges as it hit land. It happens quickly with or without rain and is especially dangerous during take-offs and landings.
What is a microburst
Tell the difference between Cumulus, Stratus and Cirrus clouds. What they look like, what color they are and where they are found.
What is 1. white, fluffy cotton ball found low in the sky. 2. gray, thin and sheet-like found low in the sky. 3. white, wispy and patchy high in the sky
The Beaufort Scale estimates this.
What is wind speed
This can cause longer take-off times and sometimes even ground planes during extreme conditions.
What is warm/hot temperatures
The difference between the summer and winter solstice and the spring and fall equinox.
What is the solstice are the longest and shortest days and the equinox are the times of the year that the days and nights are of equal length.
What is conduction and convection
Precipitation
What is a general term for various types of condensed water vapor that falls the the Earth like rain, snow and ice.
Name the three stages of a thunderstorm.
What is building, mature and dissipating
Name three things about the troposphere.
What is: 1. this is where humans live, 2. it is the first layer of the atmosphere, 3. it is where most of the weather occurs, 4. temperature differences occur here, 5. temperatures decrease with increase altitude at constant rate, 6. it is from sea level to 60,000 approximately.
The Earth rotates on its axis in this direction.
What is counterclockwise
Barometers aneroid barographs measure this.
What is air pressure
Thunder, lightning, and tornados come from this type of cloud.
What is cumulonimbus
This is the difference between the Fujita scale and the Saffir-Simpson scale.
What is tornado strength versus hurricane strength
