Weather Systems

Question 1

Three things needed for cloud formation

Answer 1

Condensation, cooling, lift

Question 2

Height at which clouds form

Answer 2

Lifting condensation level

Question 3

Four lifting mechanisms

Answer 3

Topographic, frontal, convection, convergence

Question 4

What is a front?

Answer 4

The boundary between two air masses

Question 5

Three sources of air mass

Answer 5

Polar, tropical, arctic

Question 6

Track of air mass

Answer 6

Continental and maritime

Question 7

Cloud progression in the warm front

Answer 7

Cirrus, cirrostratus, altostratus, nimbostratus

Question 8

Cloud progression in cold front

Answer 8

Cumulonimbus, cumulus

Question 9

Cold fronts are represented by

Answer 9

Triangles

Question 10

Warm fronts are represented by

Answer 10

Semi-circles

Question 11

Around mountainous areas, topographic lift can cause

Answer 11

Rain shadows

Question 12

Winds which are warmed and dried on the lee side of a mountain

Answer 12

Foehn winds

Question 13

Clouds formed when air is lifted topographically and then is unstable

Answer 13

Wave clouds (lenticular)

Question 14

If air still has momentum at the top of the mountain, it can form

Answer 14

Cumulonimbus

Question 15

Stable planetary boundary layer is when temperature

Answer 15

Increases with height then inverts

Question 16

Convective planetary boundary layer is when temperature

Answer 16

Decreases with height then double inverts

Question 17

Clouds formed by air rises by convection then sinks either side

Answer 17

Boundary layer rolls

Question 18

Boundary layer rolls with a background wind can be organised into

Answer 18

Cloud streets

Question 19

Synoptic scale convergence

Answer 19

Low pressure systems, cyclones, ITCZ

Question 20

Mesoscale convergence

Answer 20

Topography, sea breeze, gravity currents

Question 21

Heat flux which increases temperature

Answer 21

Sensible heat flux

Question 22

Heat flux which increases humidity

Answer 22

Latent heat flux
