Development of Heatwave Crisis Alert Standard for Administrative Districts Using Heatwave Risk Index

The current heatwave crisis alert system considers the daily maximum temperature alone; therefore, present study proposed a new method for estimating level. Specifically, risk index was calculated by combining regional vulnerability, as estimated using principal component analysis, and normalized temperature. level classified according to value natural breaks method. correlation coefficient between heat-related morbidity rate approximately 0.4. In addition, analysis of variance confirmed significant differences in among different levels. is limited that it does not take into account various environmental characteristics, which may results an ambiguous standard; however, this shortcoming be resolved index. Therefore, valuable assessment management Korea.
