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….)

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
