Validation of the simulations by the High-resolution Operational Ocean Forecast and reanalysis System (HOOFS) for the Bay of Bengal
Full text linkIn this report, we present a detailed comparison and validation of the simulations from high-resolution (1/480) ocean circulation model for the Bay of Bengal (BBHOOFS) using Regional Ocean Modeling System (ROMS) with the available ocean observations and the simulations by the relatively lower resolution (1/120) basinscale
general circulation model setup (IO-HOOFS), which is resently used to provide ocean forecasts for the Bay of Bengal. Comparison of vertical profiles of currents, temperature, Sea Level Anomaly (SLA) and Sea Surface Temperature (SST) for both model setups are carried for the period of 2013-2014. Comparison of the circulation features in the shelf and slope regions off the east coast of India
simulated by the model with the ADCP observations shows that simulations by the BB-HOOFS are superior in terms of its ability to capture the features and variability
in different space and time scales. In addition, simulations of currents by BB-HOOFS show high correlation and low RMSE values in the northern part of the shelf and
slope off the east coast of India compared to south. Comparison of temperature simulations by the two model setups with observation shows that the simulations of
BB-HOOFS is better, with high correlation and low RMSE values especially in the thermocline regions, compared to IO-HOOFS. However, comparison of SST and SLA simulated by BB-HOOFS with the satellite based observations is not showing any significant improvement compared to the imulations by IO-HOOFS
