21
Q

What does a Altocumulus cloud look like.

A

Commonly found on a warm and humid summer morning.

Commonly followed by thunderstorms later in the day.

22
Q

What does a Stratus cloud look like.

A

Low layer cloud​

Resembles fog but does not rest on the ground.​

No waves or patterns

23
Q

What does a Nimbostratus cloud look like.

A

Dark, low-level clouds accompanied by light to moderately falling rain. ​

Low clouds are primarily composed of water droplets since their bases generally lie below 6,500 feet.

24
Q

What does a Stratocumulus cloud look like.

A

Low, lumpy layer of clouds ​

Sometimes accompanied by weak intensity precipitation.

25
Q

What does a Cumulus cloud look like.

A

Also known as “Fair Weather Cumulus” ​

Appearance of floating cotton and have a lifetime of 5-40 minutes. ​

Can later develop into towering cumulonimbus clouds associated with powerful thunderstorms.

26
Q

What does a Towering Cumulus cloud look like.

A

Growing cumulus cloud​

On the way to becoming a Cumulonimbus

27
Q

What does a Cumulonimbus cloud look like.

A

Cumulonimbus clouds are much larger and more vertically developed than fair weather cumulus. ​

Fueled by vigorous convective updrafts (sometimes in excess 50 knots), the tops of cumulonimbus clouds can easily reach 40,000+ feet.

28
Q

What distance is Low Level Clouds.

A

Up to 6,500ft.

29
Q

What distance is Mid Level Clouds.

A

6,500ft to 20,000ft.

30
Q

What distance is High Level Clouds.

A

20,000ft to 40,000ft.

31
Q

A

Cirrus (CI).

32
Q

A

Cirrostratus (CS)​.

33
Q

Somewhat rare​

Appearance: ​
white sheet with a pebbly patter.​

Characterized by ​
high ice crystals.

A

Cirrocumulus (CC).

34
Q

Layer cloud with no definite pattern​

Steely or bluish in color​

the sun or moon can be seen dimly through them.​

the sun can appear to be behind heavily frosted glass.

A

Altostratus (AS).

35
Q

on a warm and humid summer morning is ​

commonly followed by thunderstorms later in the day.

A

Altocumulus (AC).

36
Q

Can later develop into towering cumulonimbus clouds associated with powerful thunderstorms.

A

Cumulus (CU).

40
Q

Growing cumulus cloud​

On the way to becoming a Cumulonimbus​

A

Towering Cumulus (TCU).

41
Q

This cloud is much larger and more vertically developed than fair weather cumulus. ​

Fueled by vigorous convective updrafts (sometimes in excess 50 knots), the tops of cumulonimbus clouds can easily reach 40,000+ feet.

A

Cumulonimbus (CB).

42
Q

A

Heap.

43
Q

Translation for Stratus.

A

Layer.

44
Q

Translation for Cirrus.

A

Curl of hair.

45
Q

46
Q

What are 5 other unusual clouds.

A 
Fractus.
Mammatus.
Lenticular.
Roll cloud.
Cap cloud.
47
Q

What is downburst.

A

A strong downward current of air from a cumulonimbus cloud, which is usually accompanied by intense rain or a thunderstorm.

48
Q

What are thurmals.

A

A thermal column (or thermal) is a column of rising air in the lower altitudes of Earth’s atmosphere, a form of atmospheric updraft. Thermals are created by the uneven heating of Earth’s surface from solar radiation, and are an example of convection, specifically atmospheric convection.

49
Q

Whats the difference between weather and climate.

A

Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.

50
Q

What are deicing meassures.

A

A common approach is to route engine “bleed air” into ducting along the leading edges of wings and tailplanes.

51
Q

What is wind shear.

A

Wind shear is defined as a sudden change of wind velocity and/or direction. … Vertical wind shear is defined as change of horizontal wind direction and/or speed with height, as would be determined by means of two or more anemometers mounted at different heights on a single mast
