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

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
