| Zusammenfassung |
| The Climate Analysis Seoul (CAS) being tailored for simulating detailed climate was applied
to investigate the temperature distribution around the Seonjeongneung Royal Tombs that
includes forest and grassland and in the surrounding high-density buildings in Seoul, Korea
for a hot summer days of August 6-7, 2015.
In this study, we used the digitalized topographical and land-use data of the 5 m
resolution and wind and air temperature fields of 100 m resolution produced by the numerical
model MetPhoMod (MPM), part of the CAS for the area of interest with an area of
25,000,000 m2.
The difference of the temperatures compared with the representative meteorological
station of Seoul was analyzed by considering the presence or absence of the Seonjeongneung
Royal Tombs. For the case of heat wave issued in Seoul from August 6th, 06 LST to 7th, 18
LST, 2015, the simulation results presented that averaged temperatures in the green area were
2 ∘C lower than the one of the standard weather station, whereas they showed 1.5 ∘C higher
when the green area was replaced with the building area. From this simulation
result, we can suggest that the green area has a temperature reduction effect of 1-3
∘C and its influence can be extended up to 150 m from the boundary of the green
area.
This fact reconfirms that the urban green area generates a micro-scale cool-island effect
and this local phenomenon can reduce heat stress produced by surplus thermal sources of the
surrounding buildings and paved roads during the hot summer days.
