Trung Nguyen Quang of Vietnam's  Institute of Meteorology, Hydrology and Climate Change (IMHEN) presents the Heatwave Trigger he has developped together with the Vietnam Red Cross and German Red Cross team. As there is little data on past impact, the team uses a Heat Index, combination of temperature and relative humidity. If a 6-day forecast indicates that the Heat Index will exceed the 97th percentile for two consecutive days in Hanoi, the EAP is triggered. This corresponds to a 1-in-5 years event. Trung and the team are now working to expand this trigger system to 12 cities in Vietnam.
