Abstract

Telah dianalisis pengaruh Madden Julian Oscillation (MJO), Annual Oscillation (AO), ENSO dan Dipole Mode (DM) terhadap curah hujan di Kabupaten Kapuas Hulu. Metode yang digunakan dalam penelitian ini adalah metode Fast Fourier Transfrom (FFT). Metode FFT digunakan untuk melihat seberapa besar dan frekuensi atau fenomena atmosfer  yang paling berpengaruh terhadap peningkatan curah hujan daerah pengamatan. Berdasarkan hasil analisis, maka fenomena AO paling kuat pengaruhnya terhadap curah hujan dibandingkan dengan empat fenomena lain. Pengaruh ENSO dan DM diketahui dengan menggunakan data SOI dan DMI yang dikorelasikan dengan data anomali curah hujan. Secara umum fenomena ENSO lebih berpengaruh dibandingkan dengan fenomena DM. Nilai koefisien korelasi pada saat El Nino sebesar 0,13, La Nina 0,25, DM (+) 0,03 dan DM (-) 0,05.

Kata Kunci: MJO, AO, SAO, ENSO, DM, pola curah hujan.
