Abstract

A-14-year (1979-1993) image satellites of Solar Radiation, NOAA and SeaSurface Height Anomaly of TOPEX/POSEIDON and ERS-2 have been used to study a reducing solar radiation received by the Earth (global dimming) and to predict local weather anomaly for the future climate prediction in the Indonesian region. The result shows that a dimming of solar radiation is of 16.6% during 14-year observation. It is higher than the mean increasing of global dimming of 2 - 3% for every decade. This explicitly indicates that the air pollution in the form of aerosols from industrial sectors has large contributions to this this dimming process. At the other side, there is a trend of dominant warm water in the southern Jawa-Bali that affect on the increasing of rainfall intensity in the Indonesian region. We predict that flood and a longer dark during the day time, and more variative local weather change will be more frequently happen in the Indonesian region in the futu

Abstract

Dampak pemanasan pulau perkotaan (urban heat island (UHI)) pada curah hujan ekstrem dan aerosol telah dikaji dalam penelitian ini menggunakan data curah hujan harian dan konsentrasi aerosol bulanan (NO2, SO2, dan SPM) di stasiun Badan Meteorologi Klimatologi dan Geofisika (BMKG) pada megapolitanJakarta dan wilayah pegunungan Bogor dan Citeko dari 1986-2012. Analisis harmonik dilakukan untuk menghilangkan pengaruh musiman pada hasil tren data curah hujan dan selanjutnya signifikansi tren tersebut diuji dengan metoda statistik Mann-Kendall. Hasil penelitian menunjukkan dampak pemanasanpulau perkotaan (UHI) telah terjadi secara nyata dengan tren peningkatan curah hujan ekstrem dari indikator total hari hujan 40, 50 dan 100 mm/tahun dan konsentrasi aerosol di wilayah megapolitan Jakarta dan sekitarnya dengan laju tren masing-masing sebesar 0.17 hari/tahun, 0.17 hari/tahun, dan 0.04 hari/tahun, dan 3.7e-004 ppm/tahun (NO2) dan 0.148 ppm/tahun (SO2). Namun sebaliknya terjadi tren penurunan di wilayah pegunungan Bogor dan Citeko. Hasil penelitian ini menunjukkan ada indikasi peningkatan UHI menyebabkan kenaikan konsentrasi aerosol di megapolitan Jakarta dan kondisi ini menjadi trigger peningkatan curah hujan ekstrem yang berdampak pada intensitas banjir yang semakin meningkat sejak tahun 1986.Kata kunci: Pemanasan pulau perkotaan, curah hujan ekstrem, aerosol, tren
