Tropical cyclones – Much of Vietnam’s coastline of 3,260 km is exposed to typhoons, which strike the country an average of 6-8 times per year. The storms bring strong winds, heavy rain and flooding, and result in human, economic and agricultural damage in coastal areas that can be exacerbated by high tides and storm surges. As shown in Figure 3, storms resulted in nearly US$ 4.5 billion in damage in Vietnam over the past century, and, due to population growth in exposed areas, as well as a rise in infrastructure assets, the damage potential from typhoons is increasing.Although rising sea surface temperatures are expected to increase tropical cyclone intensity in the Atlantic, uncertainties remain with regard to projections of the impact of climate change on typhoon frequency and intensity in the Pacific Ocean. A southward shift has been observed for the country in typhoon trajectory in the past five decades; if this continues, Ho Chi Minh City, a major contributor to national GDP (23%) and FDI (20%), would be at greater risk of being directly hit.
