PENGARUH ENSO TERHADAP POLA ANGIN DAN CURAH HUJAN DI DAS LARONA, SULAWESI SELATAN
Main Article Content
Abstract
Ketersediaan air di danau-danau yang berada di DAS Larona sangat penting karena air yang mengalir keluar dari danau digunakan untuk menggerakkan turbin pembangkit listrik. Kajian pola cuaca dan iklim di wilayah ini sangat dibutuhkan untuk mengetahui waktu yang tepat dalam melakukan tindakan antisipasi kekurangan air, termasuk mengadakan kegiatan teknologi modifikasi cuaca untuk menambah curah hujan. Hasil analisis dengan data angin permukaan NCEP menunjukkan bahwa pola pergerakan angin di wilayah ini dipengaruhi oleh kondisi ENSO. Pada saat El Nino Angin Timuran bertambah kuat, dan angin dari selatan melemah. Curah hujan pada saat El Nino dapat berkurang sampai 22% dari normalnya, namun pada saat La Nina dapat bertambah sebesar 50%.
Water availability in Larona watershed is very important as it is used to drive turbines of Hydro electric power. Study of weather and climate patterns is needed to anticipated water shortages, as well as to conduct the weather modification technology for rain enhancement. NCEP surface wind data analysis indicate that the pattern of wind movement in the region is affected by ENSO. During El Nino, easterly wind is getting stronger, and the southerly wind is weaker. during El Nino rainfall reduced to 22% of normal, but during La Nina it increased by 50%.
