Using Remote Sensing to Manage Cyclones
Edward Morrison
The application of remote sensing to manage cyclones can be
broken down into four categories mitigation, preparedness,
To mitigate damage from a storm before it arrives, analyst use
high resolution historical data. To plan for future hazards you need
to know the frequency and intensity of huricanes in the area.
Catagorizing land cover can help determine how much damage
and costs an area will face. building assesment uses mediam and
high resolution visual specteral bands.AVHRR and MODIS
are examples of sensors used for checking building dammage.
Remote sensing data from the U.S. National Oceanographic and
Atmospheric Administration (NOAA) are used. The Advanced Very
High Resolution Radiometer (AVHRR) is
the best type of sensorwith red & thermal bands used.
Durring a weather event forecasters need
sensors that relayinformation in near real time, this
informationis vital for early warnings of incoming
cyclones.
Microwave sensors are epically important because
they can identify areas inidated by floodwater.
Passive microwave sensors can predict total water
in a storm, the rate of rainfall and ocean surrface wind
speeds. Active microwave sensors are also used to
messure sea winds. Onshore radio wave sensors are
also important in storm detection. Agian, to prepare
durring a weather event geostationary microwave
sensors are used.
After a storm has hit remote sensing and vector
models can be used to help make the region safer in
the future. (see case study)
