Summary

Course description:

Ocean model is a representation of a numerical mathematical equation of the ocean and its interaction with atmosphere and land. The ocean model in Maritime Continent aims to capture the complex interaction between ocean and atmosphere in this region, therefore configuring an ocean model for certain area needs to specify specific domain, type of the equation and numerical methods used, the parameterization of subgrid 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, and salinity data, and other variables, and run over a period of time, typically several years, to simulate the evolution of the ocean under different conditions.

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

BMKG OFS consist of 3 primary components: Ocean Wave Model, Ocean Circulation Model, and Drifting model. Ocean Wave Model named Ina-Waves used to support sea waves information. Ocean Circulation Model named Ina-Flows, 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 on ocean modelling in terms of marine warning and forecast. The way that ocean numerical modelling systems developed by BMKG support operational analysis and forecast of ocean parameters (waves, ocean currents, sea temperature, salinity, and sea water level ) will be also discussed.  The processing and visualization met-ocean data set from BMKG-OFS using open source applications will be discussed briefly as supporting tool for data observation in the provision of marine meteorology services.
