1
Q

beyond the eye wall

A

clouds but not too tall, tornadoes

2
Q

the eye of storm

A

calm conditions
cold air is sinking towards ground
no evaporation or condensation nor clouds

3
Q

further away from wall

A

heavy rain thunder

4
Q

eye wall

A

tall black clouds

lots of evaporation and condensation that creates clouds

5
Q

stage 1 of storm

A

sun warms the ocean to 27 oc , evaporation happens

6
Q

stage 2 of storm

A

the moist, wet warm air rises rapidly, causing low pressure conditions

7
Q

stage 3 of storm

A

as the air rises it cools and condenses and the rising air draws in more moisture from the oceans causing strong winds

8
Q

stage 4 of storm

A

the Coriolis effect causes the air to spin upwards. some cooled air sinks back down to create calm central eye

9
Q

stage 5 of storm

A

as the air rises and condenses it forms cumulonimbus clouds, which causes heavy rainfall

10
Q

stage 6 of storm

A

air rushes in forms higher pressure areas outside the storm to lower pressure areas at the centre of the storm creating winds

11
Q

names of tropical storms

A

hurricanes - the Americas
cyclones- indo-Australian plate location, eastern Africa western Australia.
typhoons- east Asia

12
Q

how many tropical storm happen per year

A

80-100

13
Q

where do they occur

A

they develop in the tropics (Capricorn and cancer).

warm tropical air rises to create an area of very low pressure

14
Q

layout of tropical storm

A

diverging air flow in
upper atmosphere

                                    eye             

near surface convergence
of moist warm air

cold air is sucked in to replace the rising air this in turn is
warmed

                                                                spiral band of 
                                                                 thunderstorms                   

                                          ocean
15
Q

what direction do storms travels

A

east to west
due to earth’s spin, when they hit land they lose energy, the warm moist ocean and friction increases so storms die out , decay.
once they hit land it becomes less predictable, but in the northern hemisphere it moves north and the southern moves south

16
Q

coriolis effect

A

makes the tropical ocean spin
they spin to the right in the northern hemisphere n to the equator
left in the southern hemisphere

17
Q

warm atmosphere

A

warm air holds more water meaning heavy rainfall

18
Q

sea levels will rises

A

bigger storm surges
