Chapter 13 - Cloud Formation

Question 1

What can cause air to cool when it is moving

Answer 1

A different surface below ie sea to land

Question 2

What happens when air meets the isothermal part of the atmosphere

Answer 2

It is false to spread out - this can be the anvil

most common for air to be stable above this

Question 3

Give the process of up life to form a cloud

Answer 3

air is false to rises
as it rises it is cool adiabatically because it is expanding
starts to condense which creates a cloud

Question 4

Turbulent uplift / mixing =

Answer 4

is causes by surface friction or surface heating to a height of 3000ft
Air will mix to an extent that it reaches dew point and forms a cloud.
Inversion stops it from rising any higher

Question 5

Orographic / Topographical clouds

Answer 5

The air meets a mountain range and it false to rise which means it cools adiabatically. reaches dew point and forms a cloud

Question 6

What happens if it is warm stable air going over a hill

Answer 6

it will be using the SALR and cause condensation quicker and have to precipitate. Once over the hill the air will be dryer and warmer

Question 7

What cloud is form on a hill in dry condition?

Answer 7

Lenticular

Question 8

Convergence uplift

Answer 8

Two air masses are converging of the ground and get heat by the surface it causes the air to rise and cool adiabatically. forms a cloud.

Question 9

Frontal clouds

Answer 9

A warm front moves and will false the air upwards when it meets cold, causing adiabatic cooling
A cold front moves and meets warm air which will false itself underneath therefore causing the air to rise - adiabatic cooling.

Question 10

What causes the cold nose

Answer 10

surface friction causing warm buoyant air to be below and rise rapidly

Question 11

Give names of cloud for St,Ns,As,Cs,Ci

Answer 11

Stratos
Nimb-stratos
Alto-stratos
Cirrus-stratos
Cirrus
