2 weather hazards Flashcards
name the pressure belts in order
plolar, ferel, hadley
how should you remember the pressure belts
peter fucks hayley
hot air is closest to the surface in every cell except the…
polar cell
what temperature does water have to be for there to be a tropical storm
27C
i terms of degrees, where are tropical storms located on the planet
5-30 degrees from the equator
what causes a tropical storm
hot water evaporates into gas and rises to the clouds where it the condenses and therefore rains at high pressure
why are storms located by the equator
more hot water there
what are the features of a tropical storm
hot, intense, high pressure in the eye
where does ascending air go and then descending air
descending goes through the clouds where ascending goes up through the eye
what increases as storms move over the ocean
energy and therefore windspeed
from the top, list the high pressure and low pressure belts
low high equator high low
what three factors of a storm will climate change affect and why
frequency- water stays hot for longer
distribution- more hot water
intensity- more hot water
three ways to mitigate the risk of a tropical storm
monitor plan and protect
social and economic effects of the bostcastle flood
social-75 businesses and builidngs destoryed/damaged
economic- 20 million claimed in loans and a collapse in local toruism
what were the long term responses of the bostcastle flood
car park was raised
trees were removed
flood defences were built.
describe the process of air circulation
- sun warms the air at the equator
-moves away from the equator as it moves between high and low pressure

what is your example of a tropical storm
hurricane katrina
3 primary effects of your tropical storm case study
80pc of the city was flooded
2000 dead
flood defences shattered
3 secondary effects of your tropical storm case study
10000 homeless
3 million no electricity
food shortages and looting
short and long term responses to your tropical storm case study
poor short term response, slow evacuation
50 billion in aid
big pumps to pump water out of the city
how was the bostcastle flood caused
tail end of a hurricane and low pressure. rain was stored and ready to go
two pieces of evidence for climate change
- tree rings have grown, which show that the temp has got warmer
- pollen analysis
- temperature records
