| Zusammenfassung |
| Since the industrial revolution, the geographical extent of cities has increased around the
world. In particular, following three decades of rapid regional economic growth,
many Asian megacities have emerged and continue to expand. Short-term urban
redevelopment is, therefore, inevitable. However, in this region the microclimatic impacts of
urban redevelopment have not been extensively investigated using long-term in-situ
observations. In this study, changes in surface sensible heat exchange, heat storage, and
anthropogenic heat emissions due to urban residential redevelopment were quantified
and analyzed based on a three-year micrometeorological record from the Seoul
metropolitan area. The results show that following urban redevelopment of compact
high-rise residential buildings, 1) the daily minimum air temperature near the ground
surface increased by ∼0.6 K; 2) the ratio between surface sensible heat and net
radiation increased by ∼ 9% (summer) to 31% (winter), anthropogenic heat emissions
increased by 12 Wm−2 (spring) to 26 Wm−2 (summer), and daily maximum heat
storage ranged by 35 Wm−2 (spring) to 55 Wm−2 (summer), and; 3) there was a
transition of local circulation with changes in the surface properties of heat sources and
roughness. |
