Abstract

With the global temperature rises, South Korea frequently experiences heat wave, tropical nights and abnormal high temperature phenomena. Impacts of such heat wave, even if at the same intensity, can vary according to individuals' adaption to heat wave and regional climate characteristics. This study thus aims to examine the impacts on regional heat-wave frequency on heat-related disease deaths, and to propose heat-wave reduction measures for the minimization of heat wave damage. Various domestic and overseas heat-wave criteria and regional heat-wave criteria were examined. Based on the domestic heat wave criteria, guidelines for watch and warning over heat wave, the regional heat wave occurrence frequency was analyzed, and the correlation between the frequency, and heat-wave-affected deaths, and death rates was analyzed. Regional heat wave occurrence days and heat-wave-affected death rates were analyzed, revealing that regions with more occurrences of heat wave had a high heat-wave-affected death rate (about 76%), and that even regions with a low correlation between heat wave and death rate had a death rate of about 24%. In addition, heat wave reduction measures to minimize such heat wave damage were proposed, and a need to prepare differentiated heat wave countermeasures considering the aforementioned regional characteristics was indicated.
