3 region of tropical cyclone
Hurricanes/ cyclones and typhoons
1 of 27
how do tropical cyclone form
tropical cyclines only form where seawater temperature s are above 26.5 degrees
2 of 27
where do tropical cyclone occur
they occur in the tropics 5o and 30obof latidude
3 of 27
what are tropical cyclone measured in
saffir simpson
4 of 27
key characteristic of a tropical cyclone low pressure
Very warm moist air rises through the atmosphere , sucking more air up behind it
5 of 27
key characteristic of a tropical cyclone rotation
the earth spin helps the rising air to spiral and drags in strong winds
6 of 27
key characteristic of a tropical cyclone structure
tropical cyclone form a cylinder of rising, spiraling air surrounding an eye of descending, high pressure air
7 of 27
Coriolis force
a force created by the spin of the earth
8 of 27
where is hurricanes
caribbean sea - south east and east of the usa
9 of 27
where is typhons
south asia - north Atlantic, eastern north Pacific
10 of 27
where cyclones located
south east asia
11 of 27
saffir simpson scale
hurricanes are classified according to wind speed using a scale it measures and then categories each storm
12 of 27
what makes cyclones intensify
water temperature is nover 26.5 degees and there is low wind shear and there is high humidity
13 of 27
what makes tropical cyclones dissipate
reach land because they lose energy / move into areas of cold water and run into a system where winds blowing opposite direction
14 of 27
secondary hazards of tropical cyclone
storm surges/ landslides/ coastal flooding
15 of 27
storm surge
A storm surge is a massive wave of water that sweeps onto land where the eye of a hurricane comes a shore(dangerous for people living along the coast)
16 of 27
a storm can intensify into what
A tropical cyclone since warm ocean water gives it more power
17 of 27
social impacts of tropical cyclone
category 4 and 5 tropical cyclone have winds speed that can knocck down houses, leaving people homeless, as well as destroying power lines, leaving people without power and blocking roads with fallen trees and debris
18 of 27
impacts of storm surge
they do damage to people and the enviroment.storm surges drown people, sweep away buildings,destroy crops,contaminate agricultural land with salt, and cause se```````````````````wage spills that threaten public health through waterborne diseases
19 of 27
how countries are physically vulnerable to tropical cyclone
low lying coastal areas are vulnerable to storm surges
20 of 27
how countries are socially vulnerable to tropical cyclone
poor people are often hit worst because poor people live at high density on low lying area, in poor quality housing
21 of 27
how countries are economically vulnerable to tropical cyclone
rich,developed countries have better prediction,protection and evacuation technology.
22 of 27
how countries can prepare to tropical cyclone
To prepare for a tropical cyclone means to pre-empt the event before such as evacuating people and warning people who live in dangerous area.
23 of 27
how countries respond to a tropical cyclone
To respond to a tropical cyclone mean to react during or after the even to reduce the impacts the cyclone could cause such as rebuilding damage area and rescueing
24 of 27
xplain how people can respond to a tropical cycline
Teams of rescue workers can search for trapped people in collapsed people. The speed at which these teams can get to affected areas will change the umber of deaths in an area
25 of 27
explain how people can prepare for a tropicla cyclone
people are told to craete emrgency packs with bottled water, battery powered torches and tinned food.warm clothing and bedding is also encouraged
26 of 27
how do developed countries have more protection to tropical cyclone
people in developed countries can afford cars to get away and have mobile phones, tv, which gives them warning/ developing countries have low-quality housing and material and the education bad so might not understand government warning
