Reducing The Effects of Tropical Storms Flashcards
how can TSs be monitored?
by satellites and aircrafts
how can satellites predict TSs?
cloud pattern/altitude/What is the satellite called launched in 2004?/what does it do?/at how many degrees?
by satellites:
there is a classic cloud pattern that is associated with TSs. if rainclouds reach 16km in altitude, they are m ore likely to indicate TSs will intensify in 24h.
in 2004, The Global Precipitation Measurement Satellite was Launched. It monitors precipitation every 3 hours between 65 degrees north and south of the equator.
how can aircrafts help monitor TSs?
how many feet do they go through TSs?/what data do unmanned aircrafts collect?/what do they release and what does that do?
Aircrafts:
specially equipped and unmanned aircrafts frequently go through TSs at 10,000 feet to collect Datta: air pressure, wind speed data.
they release dropsondes (sensors) which send measurements to radio
what is the aircraft called that NASA uses to monitor TSs?
where does it monitor TSs?
what 2 things do they have that help scientists to do what ?
NASA monitors weather across the Atlantic using two unmanned aircrafts called the ‘Global Hawk Drone’.
they have on board radar and microwaves to help scientists understand more about the formation of TSs to improve forecasting models.
which company develop supercomputers?
what can supercomputers predict? (2)
What was predicting TSs like in 1992 compared to now ?
pros and cons of supercomputers?
NOAA developed 2 supercomputers which can predict the path and intensity of the TS.
in 1992, the location of TSs could be [predicted within 3 days before the TSs hits but could be wrong by 480km.
supercomputers now give 5 days warning and accurate location by 400km.
name a cyclone that was successfully prevented thanks to supercomputers and another example where it wasn’t.
How many people died or survived in each year
in 2013, cyclone Phailin in India was successfully predicted. 12 mill people evacuated.
in 1999, a similar cyclone hit a similar area but more than 100,00 people died.
what 3 things can help prevent storm surges?
what 2 things can trees do to reduce wind energy?
slat marshes, wetlands, and ,mangroves can protect against storm surges by reducing the waves’ energy.
Trees reduce wind energy and trap debris that is wanting is cause damage.
is protection possible?
what example of mitigation can homeowners do to protect against TSs?
what does FEMA advise homeowners to do to protect against TSs?
buildings cane be reinforces to reduce damage form TSs, this is called mitigation.
FEMA advises homeowners to:
1) install hurricane straps Protective layer of metal) between roofs and walls
2) install storm shutters on windows
3) install an emergency shelter
4) remove trees close to buildings
how can planning reduce the risks ?
what week encourages people to plan what they need to do in an event of a TS.
American National Hurricane Preparedness Week in May aims to encourage people to plan what they need to have and do in an event of a TS. Advice included:
preparing disaster supply kits
1) Having fuel in vehicles
2) Knowing where official emergency shelters are
3) Planning with family what to do
