Observation data (1981-2014) and climate change scenario data (historical: 1981-2005; RCP 2.6 and 8.5: 2006-2100) were
used to analyze occurrence and future outlook of the extreme heat days and tropical nights in Daegu and Jeju. Then we
compared the mortality and observations data (1993-2013). During 1981-2014, the average of extreme heat days (tropical
nights) was 24.41 days (12.47 days) in Daegu, and 6.5 days (22.14 days) in Jeju. Extreme heat days and tropical nights have
been similarly increased in Daegu, but tropical nights increased more than extreme heat days in Jeju. Extreme heat days and
tropical nights in both, Daegu and Jeju showed high correlation with daily mortality, specifically Daegu’s correlation was
higher than that of jeju.
The yearly increasing rate of extreme heat of the future (2076-2100) was 1.7-3.6 times and 7.8-37.7 times higher than the
past (1981-2005) in Daegu and Jeju, respectively. The yearly increase rate of tropical nights of future was 2.6-5.0 times and
2.9-5.6 times higher in Daegu and Jeju, respectively. During 2006-2100 periods, the trend of extreme heat days was observed
both in Daegu and Jeju. On the average, extreme heat days and tropical nights in Jeju increased more than that of Daegu.
However, the trend of extreme heat days increase in Daegu was higher than that in Jeju, whereas, the trend of tropical nights
in Jeju was higher than that in Daegu.
