Summary

Course description:

The Ocean model represents a numerical mathematical equation of the ocean and its interaction with the atmosphere and land. The ocean model in the Maritime Continent aims to capture the complex interaction between ocean and atmosphere in this region, therefore configuring an ocean model for a certain area needs to specify a specific domain, type of the equation and numerical methods used, the parameterization of sub grid-scale processes and forcing data used to drive the model, such as atmospheric data and boundary condition.

One of the most commonly used ocean models is the three-dimensional numerical model, which divides the ocean into a grid of cells and uses mathematical equations to simulate the physical processes within each cell. The model is initialized by ocean currents, temperature, salinity data, and other variables, and run over some time, typically several years, to simulate the evolution of the ocean under different conditions.

Among those models that existed, BMKG developed the BMKG Ocean Forecast System (BMKG-OFS) as one of the Meteo-Oceanography modelling systems used to support prediction and information about waves, ocean currents, salinity and sea temperature for the communities. The development of BMKG OFS is an attempt to fulfil community needs in various sectors such as sea transportation, fisheries, mining and energy, and marine-related activities.

BMKG OFS consists of 3 primary components: the Ocean Wave Model, Ocean Circulation Model, and Drifting model. The Ocean Wave Model named Ina-Waves is used to support sea wave information. The Ocean Circulation Model named Ina-Flows, is used to support current, salinity and sea temperature information at every depth. The drifting model is used to support object trajectory, sea level and coastal flood information.

This training will provide participants with a basic knowledge of ocean modelling in terms of marine warnings and forecasts. The way that the ocean numerical modelling system developed by BMKG supports operational analysis and forecast of ocean parameters (waves, ocean currents, sea temperature, salinity, and seawater level) will be also discussed.  The processing and visualization of met-ocean data set from BMKG-OFS using open-source applications will be discussed briefly as supporting tools for data observation in the provision of marine meteorology services.
