Atmosphere
Thunderstorms
Fronts
Clouds
100

Iced caused by small droplets found in layered clouds that is rough and white 

Ryhme Ice

100

These two gases compose 98.5% of the atmosphere 

Nitrogen and Oxygen 

100
These three conditions lead to the development of thunderstorms 

Unstable Atmosphere, Moisture, Lifting action 

100

Large region of Air that has the similar characteristics of the surrounding area

Air Mass
100

a surface based cloud composed of either water droplets or ice crystals.

Fog

200

Ice formed by larger drops usually from in cumuliform clouds that freeze on contact 

Clear ice 

200

The lowest levels of the Atmosphere where almost all weather occurs  

Troposphere 

200

A line of multiple thunderstorm/cells that advance together 

Squall line

200

The front moves fast close to the ground and develops thunderstorms and cumulous clouds 

Cold Front 

200

The Latin Suffix of -Nimbus denotes what in clouds 

Rain 
300

 a change in wind speed and/or direction over a short distance. It can occur either horizontally or vertically and is most often associated with strong temperature inversions or density gradients.

Wind shear 

300
The point at which the Troposphere and Stratosphere meet 
Tropopause 
300

a localized column of sinking air (downdraft) within a thunderstorm and is usually less than or equal to 2.5 miles in diameter.

Microburst 

300
This front has high humidity and a stratiform layer of clouds, with light drizzle and low visibility. 

Warm Front 

300

 possess a flat and uniform type texture in the mid levels

Strato type clouds 

400

 Air movement that normally cannot be seen and often occurs unexpectedly

Turbulence 

400
This force caused by the rotation of the earth causes rightward deflection in the Northern hemisphere. 

Coriolis Affect 

400

menacing looking multi-level clouds, extending high into the sky in towers or plumes

Cumulonimbus clouds

400

a weather front or transition zone between two air masses (cold and warm), when neither air mass is advancing into the other at a speed exceeding 5 knots at the ground surface.

Stationary Front

400

Clouds formed by vertical currents in unstable air that are characterized by their lumpy, billowy appearance.

Cumulus clouds 

500

very small solid particles ejected from a volcano during an eruption which have intermediate axes measuring between 1/16 (0.625) mm and 2 mm

Volcanic Ash  
500

Energy from the sun that hits the earth causes all weather and wind 

Uneven Heating and cooling 
500
The highest altitude a strong thunderstorm can develop to

75,000

500

forms when a warm air mass gets caught between two cold air masses.

Occluded Front 

500

 thin, feather-like ice crystal clouds in patches or narrow bands. Usually found at high altitude.
