hurricanes Flashcards
what us the most important measurement when deciding category of a cyclone
wind speed in cyclone
a county regularly effected by cyclones
indonesia
which latitudinal zone is most effected by tropical cyclones
10-30
explain two ways why a map which shows risk of flooding at different areas is useful when countries prepare
- threat to high-value infrastructure
- low lying areas
explain why tropical cyclones lose their power over land
there energy source of warm water - above 26 degrees - is cut off
explain one reason why low-lying coastlines are vulnerable to tropical cyclones
- vulnerable to storm surge flooding = caused by low air pressure within cyclones
- vulnerable to large waves =. driven onshore by intense winds
explain why GIS cyclone track map is useful for preparation
- shows intensity of wind speeds = measures can be put in place to evacuate people
- shows speed at which storm is moving = populations given accurate predictions
- shows coastal areas that might be effected by storm surges = evacuation
- enables countries to predict the path of cyclone = which areas to evacuate
explain two reasons for the link between sea surface temp and cyclone distribution
warm sea surface temp are near equator = correlates to pattern of hurricane around equator
cyclones only form north or south of the equator, but not on equator = where there is rotation of air caused by the coriolis force
explain one economic impact of tropical cyclones
repair costs high = government had to reinvest in infrastructure = other services such as education having reduced spending
production of oil fell = meant that global price of oil rose = having a negative effect on consumers around the wall
