Ocean Environment Prediction
(South Chine Sea)
Coupled ocean wave and circulation models have been implemented using the third generation wave model, WAM, and SEAOM (South East Asian Ocean Model, based on POM - Princeton Ocean Model). The models are coupled through wave-current interaction terms. The modelling capability has been further improved from altimeter data in terms of better boundary inputs such as tidal elevations generated by data driven techniques. Data assimilation of altimeter data and physical measurements, if any, is a new feature of the prediction system. WAM and SEAOM run in parallel, exchanging data as they execute. This work is aimed at a comprehensive ocean modelling system for the regional seas surrounding Singapore waters. These models are currently used operationally by the Meteorological Services Division of the National Environment Agency (MSD/NEA) in Singapore.

IOEPAS 2.0
IOEPAS 2.0 (Ocean Environment Prediction and Assimilation System) is a TMSI-created package consisting of coupled WAM and SEAOM programs featuring a graphical user interface (GUI) which allows for: convenient entry of parameter values; convenient execution of the backend programs; monitoring of the program executions; and convenient viewing of results.
