Curah Hujan, musim, klimatologi, Papua Barat DayaAbstrak
Provinsi Papua Barat daya terkenal dengan wilayah yang didominasi oleh pegunungan sehingga akan mempengaruhi kondisi curah hujan di wilayah tersebut. Tipe hujan lokal umumnya mempunyai bentuk huruf “A” dengan satu puncak curah hujan tertinggi di pertengahan tahun dan pola hujan ini biasanya terjadi di wilayah yang dipengaruhi oleh karakteristik lokal seperti topografi pegunungan ataupun angin lokal, hujan maksimum pada saat pola lokal biasanya terjadi pada bulan Juni dan Juli. Sebagai upaya mewujudkan hasil prakiraan iklim yang baik BMKG telah memperbarui data rata-rata klimatologi dari Normal Curah Hujan periode 1981 – 2010 menjadi Normal Curah Hujan periode 1991 - 2020. Pedoman terbaru ini telah digunakan sebagai acuan untuk penentuan tipe pola hujan di wilayah Indonesia termasuk Indonesia bagian timur, Papua Barat Daya. Berdasarkan hasil pengolahan curah hujan di beberapa pos hujan wilayah Papua Barat Daya tahun 2020 - 2024 hasilnya menunjukkan terdapat dua tipe pola hujan yaitu tipe Lokal 1 di pos hujan Majener, Malagusa, Klasmelek, Stasiun Meteorologi DEO Sorong, Stasiun Geofisika Sorong, dan terdapat juga tipe Lokal 2 di pos hujan Walal, Klamalu, Mariyai dan Waisai. Puncak curah hujan tertinggi umumnya berada pada bulan Juli dan Agustus dengan kisaran 300 - 600 mm/ bulan, sedangkan puncak curah hujan rendah umumnya terjadi pada bulan Februari dengan kisaran 0 - 100 mm/bulan.
