Dampak Asimilasi Data Radar Produk Cappi pada Prediksi Kejadian Hujan Lebat di Jabodetabek Menggunakan Model WRF-3DVAR

Abstract: Penelitian ini mengevaluasi dampak asimilasi data radar pada model WRF untuk prediksi kejadian hujan ekstrim di wilayah Jabodetabek pada tanggal 11 Desember 2017 yang disebabkan oleh angin monsun barat serta adanya konvergensi dan shearline di wilayah utara Pulau Jawa. Dua eksperimen model WRF, yaitu (1) tanpa asimilasi data dan (2) dengan asimilasi data reflektivitas radar cuaca produk CAPPI (Constant Altitude Plan Position Indicator) dengan teknik 3DVAR dilakukan untuk memprediksi 24 jam ke depan menggunakan… Show more

“…In addition, Paski et al (2017) also conducted the same study in Lampung region. Paski et al (2019) also did a new experiment with the latest engineering research on the assimilation of radar 3DVar data in Jakarta using Z data of Constant Altitude Plan Position Indicator (CAPPI) products as the results provide better spatial rain distribution simulations…”
