Tropical cyclones are powerful hydro-meteorological hazards. On average, over 78 million people are affected globally by between 50 to 60 events each year. Tropical cyclones are unevenly spread around the globe as their development depends on specific climatic and oceanic conditions. A tropical cyclone has multiple impacts on the affected areas, including:
- Extremely powerful winds.
- Torrential rains leading to floods and/or landslides.
- High waves and damaging storm surge, leading to extensive coastal flooding.

The complexity of the multiple forms of impact triggered by tropical cyclones would call for integrated modelling of wind, rain, storm surge and landslides. However given the limited time available for the present study, priority was given to modelling the winds and storm surge.
