Abstract

The current standard level of Heat Health Watch Warning System consider both daily maximum temperature and daily maximum heat index(HI), but current standard could not consider daily maximum HI due to the difficulties in forecasting when we consider both daily maximum temperature and daily maximum HI and no considering HI because relative humidity could not observed for some regions. So, Newly established standard level of Heat Health Watch Warning System is based on daily maximum temperature exceeding for two consecutive days or daily minimum temperature exceeding and daily maximum temperature exceeding . These days are called heat days. On extreme heat days, the standard of extreme heat advisory is based on daily maximum temperature among exceeding and not exceeding , and extreme heat warning is based on daily maximum temperature exceeding . ANOVA analysis was carried out using the data of Seoul Metropolitan City in 1994 to check the robustness of the new standard level of Heat Health Watch Warning System from this study, in particular for mortality variable. The results reveal that the new standard specifies excess mortality well, showing significance level of 0.05 in the difference of excess mortality for each phase.
