100

You'll find all the weather there.

What is the Troposphere?

100

It is decreased when there is warming from below.

What is stability?

100

Frost forms when the dewpoint is at or below this.

What are freezing temperatures?

100

These stand between two air masses.

What is a front?

100

These three (unstable air, lifting action, and high humidity) will get you one of those.

What is a thunderstorm?

200

Named for the French scientist who discovered anything in flight will have a curved path due to this force.

What is the Coriolis force?

200

Described as "getting warmer as you get higher."

What is an inversion?

200

Calculate that to predict the possibility of fog and low clouds.

What is the temperature-dewpoint spread?

200

When you fly across a front, you can notice these changes.

What is a change in temperature, wind direction or speed?

200

Cumulus, Mature, and Dissipating are defined as these.

What are the stages of a thunderstorm?

300
It reduces the Coriolis force and causes wind to shift to the right at higher altitudes.

What is Frictional force?

300

The surface-based inversion must have this kind of wind and clear nights.

What is calm winds?

300

It's this type of air that result in stratus clouds.

What is stable air?

300

Steady precipitation and little turbulence is the product of that kind of front.

What is a warm front?

300

Severe turbulence, lightning, and hail... reason enough to stay away from these clouds.

What are cumulonimbus clouds?

400

The result is cool, dense air moving inland from over the water.

What is a sea breeze?

400

This is the temperature when the air can hold no more vapor; it is saturated.

What is dewpoint?

400

The wind blows moist air over cool surfaces to produce this type of fog.

What is advection fog?

400

It is not a front, but only a difference in moisture levels between two air masses.

What is a dry line?

400

Keeping a level one of these protects the airplane from over-stress when subjected to severe turbulence.

What is a flight attitude?

500

These variations are due to unequal heating.

What causes variations in altimeter settings?

500

Condensing water vapor will cause these.

What are clouds?
500

Those are the cloud types which come from unstable air.

What are cumulus clouds?

500

As cold fronts go, the unstable air is on that side of it.

What is the warm side?

500

Thermals produce these, and cause convective turbulence.

What are towering cumulus clouds?
