ANALISIS ANGIN ATAS DI WILAYAH JAWA BAGIAN BARAT SELAMA KEGIATAN TMC REDISTRIBUSI CURAH HUJAN
Main Article Content
Abstract
Intisari
Telah dilakukan analisis angin pada berbagai level ketinggian pada saat penerapan TMC yang dilakukan pada tanggal 26 Januari s.d 27 Februari 2013. Data yang digunakan adalah data angin tiga jam-an MERRA (1.25o x 1.25o), data angin harian NCEP (2.5o x 2.5o) serta angin gradient dari BOM Australia. Selama kegiatan, angin baratan mendominasi wilayah Jawa bagian barat. Arah angin di Jawa bagian barat sangat dipengaruhi oleh gangguan tropis yang muncul di Samudera Hindia sebelah selatan Indonesia. Terjadi pembalikan arah angin dari angin baratan menjadi angin timuran akibat pengaruh Siklon Tropis Gino di sebelah barat daya Sumatera. Kecepatan angin pada akhir kegiatan mencapai 20 m/s akibat pengaruh Siklon Tropis Rusty di sebelah barat Australia.
Abstract
The Application of weather modification has carried out to redistribute precipitation over Jakarta and the surrounding on 26 January to 27 February 2013. Data used in this study are 3 hourly MERRA wind data (1.25o x 1.25o), daily NCEP wind data (2.5o x 2.5o), and gradient wind analysis data from BOM Australia. The westerly wind dominated over western part of Java.The wind direction in the western part of Java is strongly influenced by the tropical disturbance in the Indian Ocean south of Indonesia. The Tropical Cyclone Gino over Southwest Sumatera caused easterly wind over west part of Jawa. The wind speed up to 20 m/s due to the effect of Tropical Cyclone Rusty in the west of Australia.
