Abstrak

Pada tanggal 11 Januari sampai dengan 14 Februari 2014 telah dilaksanakan penerapan teknologi modifikasi cuaca (TMC) untuk menanggulangi banjir di wilayah Jakarta dan sekitarnya. Selama kegiatan tersebut fenomena ENSO dan IOD dalam kondisi normal. MJO menunjukkan aktifitas konvektif netral di wilayah Indonesia pada pertengahan Januari hingga pertengahan Februari 2014. Temperatur  permukaan laut di perairan Jawa bagian barat sekitar 28-290C. Kelembagan udara pada level 850 mb sekitar 70-80%. Pertumbuhan awan umumnya berada di sebelah barat daya, barat dan barat laut Jakarta. Indeks Monsoon Australia positif berpengaruh terhadap peningkatan pembentukan awan hujan di Jawa.

Abstract
Application of weather modification has carried out to reduce precipitation over Jakarta on 11 January to 14 February 2013. During this period, El Nino Southern Oscillation and Indian Ocean Dipole Mode were normal condition. The Madden Julian Oscillation shows that the convection over Indonesia region was netral condition. The sea surface temperature over west part of Java waters was 29-30 290C. The 850 mb average of relative humidity on mid January - mid February 2014 was 70-80%. Based on visual and weather radar observation, cloud development mainly over northwest to southwest of Jakarta. Positive Australian Summer Monsoon Index affected to increase precipitation over Java area.
