100
How clouds are classified.
What are its height and its formation?
100
The main cause of airflow disturbance.
What is the change in temperature?
100
This cloud type will form in stable air.
What are stratus clouds?
100
Today's date.

The composition of low clouds.

What are water droplets and sometimes ice crystals?

300
The 4 categories of cloud height.
What are low clouds, middle clouds, high clouds, and clouds of development?
300
When displaced air does not resist to change.

400

Clouds that are white and puffy at an elevation of 18,000 feet AGL.

What are altocumulus clouds?

400
High clouds are not composed of this.
What are water droplets?
400

What happens when a mass of rising air is still warmer than the new air around it? What type of air stability does this cause?

The air will continue to rise due to physics, causing the air to become unstable.
400
Explain how clouds are formed.

A drop in temperature to the saturation point of the air or the temperature is constant but the amount of water in the air increases.

400
What is the elevation of a cloud by the name of altostratus and what type of formation is it?
Middle cloud, stratus type formation.
500

Clouds that are greyish and flat and at around 30 000 ft AGL.


What are cirrostratus clouds?
500
Explain clouds of vertical development.

Clouds that range from 1500 feet to the lower levels of the stratosphere which are associated with thunderstorms and other phenomena which occur during the summer months.

500
What are 3 flight characteristics of stable airflow?

All possibilities:

1. poor low-level visibility (fog may occur)

2. stratus type cloud

3. steady precipitation

4. steady winds


500

Briefly describe 2 of the following:

1. convection

2. orographic lift

3. frontal lift

Can buildings affect air stability? If so, how?

Yes, it can. Through friction.
