Véderdő telepítésének lehetséges jövőbeli hatásai Szeged hőterhelésében

Absztrakt

In this study the possible future thermal consequences of a fictional protective forest around Szeged were examined. The aims of this installation are the adaptation to climate change and reducing air pollution. However, the complex effects of local urban climate should be taken into consideration as well. Therefore, the changing of heat load due to the forest was studied by presenting the change of climate indices during the 21st century. In order to simulate the local circumstances of the city, a MUKLIMO_3 local scale model was applied. EURO-CORDEX regional model simulations ensured the climate data for periods 2021–2050 and 2071–2100 using scenarios RCP4.5 and RCP8.5. Our results show that the effect of the protective forest is not favourable in certain parts of the city due to the reduction or block of the ventilation. The forest induces cooling effect mostly during daytime, but the extent of unfavourable effects exceeds the advantages especially at night time.
