Transcript Tropical Cyclone Hazard Modelling and Mapping

Joy Papao, SPC - SOPAC
Tropical Cyclones, Typhoons & Hurricanes
Tropical Cyclone Overview - Formation
Tropical Cyclone Hazards
 Torrential rains (flash flooding & river flooding)
 Landslides
 Storm surges and waves
 Lightning
 Salt spray
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
 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
