Description

Effect of urban growth in Jakarta on temperature rise at the originally urbanized area (old city area) was investigated using a meso scale meteorological model. After the validation of the model performance using observational data, calculation of the local meteorology in dry season was carried out based on the land use data for 1970s and 2000s presumed from the population density data. Calculated results showed that 1) the averaged daytime and maximum temperatures at the old city area in 2000 were 0.6°C and 0.9°C higher than those in 70s due to the advection of heat released from the surroundings. 2) The amount of advected heat under the weak sea breeze condition for the old city area was -0.7 [W/m2] in 70s and 77 [W/m2] in 2000, respectively.
