Deskripsi Kepakaran
I am a physical oceanographer specializing in ocean climatology, wave climate, ocean extreme climate (waves and marine temperature), and wave modeling, with extensive experience in analyzing long-term ocean variability and extreme events. My research focuses on the interaction between the ocean and atmosphere across seasonal, interannual, and decadal timescales, with particular emphasis on the role of large-scale climate modes such as the Madden–Julian Oscillation (MJO), El Niño–Southern Oscillation (ENSO), and Indian Ocean Dipole (IOD) in modulating ocean surface conditions. In ocean climatology, I work extensively with global reanalysis datasets (e.g., ERA5, NCEP, CMIP) and satellite observations to characterize historical trends and variability in wave and temperature fields. I develop composite analyses and statistical models to investigate the spatial–temporal patterns of ocean conditions and their teleconnections with atmospheric processes. In wave climate research, I analyze multi-decadal patterns of significant wave height (Hs), wave period, and wave direction, identifying seasonal cycles, long-term shifts, and climate-driven variability. I have conducted event-based analyses to quantify the influence of MJO phases, tropical cyclones, and monsoon winds on wave development, particularly in the Indonesian Maritime Continent, East Asian seas, and the Northwestern Pacific. My work on ocean extreme climate examines the mechanisms and impacts of extreme marine events, including the frequency, intensity, and duration of high-wave episodes and marine heatwaves. I assess their ecological and socio-economic implications for coastal communities, marine safety, and offshore infrastructure, and evaluate how these extremes may evolve under climate change scenarios. In wave modeling, I have advanced expertise in configuring, calibrating, and validating numerical models such as WAVEWATCH III (WW3) for both hindcast and forecast applications. This includes coupling wave models with atmospheric forcing, simulating extreme events, and applying high-resolution modeling to coastal and small-island environments. I have developed hindcast databases spanning multiple decades and operational forecasting tools for wave conditions, with applications in disaster preparedness, marine navigation, and sustainable coastal planning.
