Weather hazards

Question 1

Global atmospheric model

Answer 1

the equator receives more direct radiation from the sun so it is warmer than the rest which warms the air which rises. it reaches the upper atmosphere then spreads cooling down before it cools. areas of high pressure form where the air comes down and low pressure where it goes up.

Question 2

polar cell

Answer 2

the cells of air movement at the poles

Question 3

ferral cell

Answer 3

the ‘wild’ cell between the hadley and polar cells

Question 4

hadley cell

Answer 4

the cell of air movement at the equator where the heat rises and falls, influencing the feral cells

Question 5

coriolus force

Answer 5

winds that have formed going from areas of high pressure to low pressure across the earth

Question 6

equator

Answer 6

the band around the middle of the earth which receives the most sunlight as it is closer to the sun

Question 7

tropics

Answer 7

tropic of cancer or capricorn, where there is heavy rainfall due to the falling humid air that has cooled after coming from the equator

Question 8

poles

Answer 8

the tips of the world where the earths axis goes through

Question 9

tropical storm

Answer 9

formed within the hadley cell or intertropical conversion zone, they rotate and cause damage through huge wind speeds and really heavy rainfall their fuel is warm water or water vapour

Question 10

intertropical conversion zone

Answer 10

where the trade winds cross, it is a low pressure belt of air

Question 11

cyclone

Answer 11

tropical storm in/from the indian ocean

Question 12

typhoon

Answer 12

tropical storm in/from the pacific ocean

Question 13

hurricane

Answer 13

tropical storm in/from the atlantic ocean (or from USA)

Question 14

eye of the storm

Answer 14

air descends at the centre of the hurricane, the eye is an area of calm conditions with a ring of clouds around it

Question 15

condensation

Answer 15

water vapour in the air changed into liquid

Question 16

evaporation

Answer 16

water it heated and becomes water vapour

Question 17

cumulonimbus

Answer 17

dense towering vertical cloud associated with thunderstorms

Question 18

distribution

Answer 18

how things are spread

Question 19

frequency

Answer 19

the amount of things in a certain time

Question 20

intensity

Answer 20

the degree or strength of something that happens

Question 21

climate change

Answer 21

the century scale rise in the earths average temperature

Question 22

thunder storms

Answer 22

usually include heavy rainfall and lightning occurs with thunder

Question 23

drought

Answer 23

severe lack of water over an extended time which leads to cracked soils and parched flora

Question 24

tropical continental air mass

Answer 24

warm and dry air mass that comes from southern Europe and north Africa (south of UK)

Question 25

polar continental air mass

Answer 25

cold and dry air mass from northern Europe (east of UK)

Question 26

tropical maritime air mass

Answer 26

warm and wet air mass from the atlantic ocean (south west of UK)

Question 27

polar maritime air mass

Answer 27

cold and wet air mass from the north atlantic (west of UK)

Question 28

arctic maritime air mass

Answer 28

very cold from the arctic ocean (north of UK)

Question 29

extreme weather

Answer 29

unexpected unusual and unpredictable weather which can have a devastating impact on the world
