Tropical Cyclone Risk Model
“assessing only wind hazard”
TCRM - users
Climatologists
Meteorologists
Natural hazard researchers
with limited or no programming experience
TCRM – configuration file
Input file – IBTrACS global database of tropical cyclones
www.ncdc.noaa.gov/oa/ibtracs
Domain – Country/Division/Location
Track Generator - No of years to simulate
Hazard – Return periods (25, 50, 100, 200, 250, 500….)
Viewing simulation results - graph
Cyclonic Wind Hazard for Lata, Solomon Islands
Simulation Results – Return Period
TC Track data – Quantum GIS
TC Tracking – Quantum GIS
TC Ivy - 2004
Wind field – Quantum GIS
Why Model?
To better understand the risk and potential impacts of
these natural hazard on our communities
Increase resilience
Could be used to improve early warning procedures for
TCs, in this case
May want to look at how different TC hazards affect areas
of interest
