Modified Convective Stratiform Technique (CSTm) Performance on Rainfall Estimation in Indonesia

Autor: Endarwin, Safwan Hadi, Bayong Tjasyono HK, Dodo Gunawan, Meteorology Division, Agency for Meteorology, Climatology and Geophysics, Jalan Angkasa I No. 2 Kemayoran, Jakarta 10720, Indonesia

Publikováno v: Journal of Mathematical and Fundamental Sciences, Vol 46, Iss 3, Pp 251-268 (2014)

This study has analyzed a rainfall estimation using a modified convective stratiform technique (CSTm). Unlike the original convective stratiform technique (CST), which only utilizes infrared (IR) data, CSTm applies not only IR data but also passive m

Analysis of Surface Wave Attenuation in Mangrove Forests

Autor: Safwan Hadi, Hamzah Latief, Muliddin

Publikováno v: ITB Journal of Engineering Science, Vol 35, Iss 2, Pp 89-108 (2003)

This paper presents an analytical study on surface wave attenuation in mangrove forest using analytical model developed by Massel et.al. (1999). The energy dissipation in the frequency domain is determined by treating the mangrove forest as a random
