The Challenge Of Natural Hazards Flashcards
what is the parts of the global atmospheric
its split into 3 polar cell ferrel cell hardly cell
what is global atmosphere circulation
is the tansfer of heat from the equator to the poles by the movement of air i.e
how air moves heat around the wold
why dose air move in the first place
air moves due to difference in air pressure wind blow from high pressure to low pressure
what did difference between worn air and cold air
warm air rises and its low pressure
cold air skins and its high pressure
how dose global atmospheric work
the hole system is driven by the equator (which is the hottest part if the earth) the air rises(air warming) at the equator leading to low pressure and rainfall when the air reaches the edge of the atmosphere it cannot go any further and so it travels north and south the air becomes colder and denser and falls creating high pressure and dry conditions at around 30 degrees north and south
why dose it become colder and denser
because its no longer where the equator is
what are the causes of trophicak storms and sequence of their formation of development
sea levels above 27
around summer autumn time
the distance from the equator
8-20 and 5 of the equator
how dose tropical form
the sun heats the ocean to 27 causing it to evaporation
the most warm air rises quickly
the air rises ir cools and it condenses creating large clouds (coulombs)
the large clouds bring lots of rainfall
as makes in form clouds the storm beak up the centre of the storm in strong winds
the air skins in the eye
tropical storm travels across the ocean
how might climate affect tropical storms
increase in temperature may affect where tropical storms occur they might affects places that haven’t experienced it
its fiffuclt to predict
topical storms are getting more intense
why do tropical storms spin
the Coriolis effect makes tropical storms spin
case study typhoon Haiyan
the storm started at 9am Friday in the Philippines it headed south and west
what date did typhoon Haiyan start
feb 2013
how fast did the storm go
195mph
how warm did the sea levels go up to
39 degrees
what was the effects and response to typhoon Haiyan
primary effect
40000homes damaged
strong wind damaged buildings and power lines cut off
secondary
flood caused landscape black roads
30000 fish boats destroyed
power supplies were cut off for a mouth
immediate effects
aid agencies replaced the fishing boats lost
us aircrafts and helicopters helped with search and resume
long term response
cyclone shelter were built to accommodate people evacuated from coastal areas
