chapter 9

Question 1

Clouds are composed of what 2 things

Answer 1

water droplets and ice crystals

Question 2

3 main factors that determine cloud characteristics

Answer 2

Stability of the air (type of cloud)Moisture content of the air (thickness of cloud)Temperature of the air (type of droplet)

Question 3

Stratiform clouds are what type of clouds

Answer 3

Layer clouds

Question 4

Cumuliform clouds are what type of clouds

Answer 4

clouds of vertical development

Question 5

Most clouds form as a result of?

Answer 5

Adiabatic cooling

Question 6

In stable air, when will vertical motion cease?

Answer 6

When the lifting agent ceases to operate at a given altitude

Question 7

In unstable air, when will vertical motion cease

Answer 7

Only when the temperature of the air reaches equilibrium with the temperature of the surrounding air

Question 8

what are the 5 types of cloud classified as vertical development clouds

Answer 8

CF CU TCU CB ACC

Question 9

List the 5 lifting processes

Answer 9

Convection
Convergence
frontal lift
orographic lift
mechanical turbulence

Question 10

List the major factors that which contribute to the formation and dissipation of clouds formed by orographic lift

Answer 10

Formation:
Slope steepness
Height of terrain
wind direction
wind speed
humidity
stability

Dissipation: change of air mass
change of wind direction

Question 11

List the major factors that which contribute to the formation and dissipation of clouds formed by Mechanical turbulence

Answer 11

Formation:
Wind speed
stability 
humidity
rough ground

Dissipation:
change of air mass
decrease in wind speed

Question 12

List the major factors that which contribute to the formation and dissipation of clouds formed by Convergence

Answer 12

formation:
Humidity
stability
horizontal and vertical extent of the convergence

dissipation:
change in air mass
filling of the low

Question 13

What is the product of condensation/sublimation of atmospheric water vapor which is deposited on the ground

Answer 13

precipitation

Question 14

Describe the Bergeron effect

Answer 14

when ice crystals and water droplets are present in the same environment, the water droplets will evaporate and then sublimate onto the ice crystals

Question 15

by what 2 processes do cloud particles grow

Answer 15

The Bergeron Effect and the Collision process

Question 16

What 3 types of precipitation are created by stratus clouds

Answer 16

Drizzle, Freezing drizzle, and snow grains

Question 17

What 2 clouds produce freezing rain

Answer 17

NS and AS

Question 18

How are Ice Pellets formed?

Answer 18

Snow flakes that have melted and refrozen

Question 19

Explain the difference between intermittent, continuous, and showery precipitation

Answer 19

Intermittent and continuous precipitation fall from clouds formed in stable air. intermittent precipitation falls from thinner clouds (SC,AC, ST, AS) Continuous precip falls from thick clouds (SC,ST,NS,AS) Showery precipitation falls from cumuliform clouds.

Question 20

Snow pellets can fall from which cloud if CU is embedded

Answer 20

SC

Question 21

List 3 conditions required for the formation of fog

Answer 21

Condensation Nuclei
High relative humidity
Cooling of the air or adding water vapor

Question 22

Name the 6 types of fog

Answer 22

Radiation fog
Advection fog
Steam Fog
frontal fog
ice fog
upslope fog
