A hydrological model is a useful tool to study the effects of human activities and climate
change on hydrology. Accordingly, the performance of hydrological modeling is vitally …

Systematic improvements in algorithmic design of regional ocean circulation models have
led to significant enhancement in simulation ability across a wide range of space/time scales …

Ocean currents play a key role in Earth's climate–they impact almost any process taking
place in the ocean and are of major importance for navigation and human activities at sea …

The Regional Ocean Modeling System (ROMS) is one of the few community ocean general
circulation models for which a 4-dimensional variational data assimilation (4D-Var) …

The generation and evolution of eddies in the ocean are largely due to instabilities that are
unpredictable, even on short time-scales. As a result, eddy-resolving ocean reanalyses …

Sri Lanka occupies a unique location within the equatorial belt in the northern Indian Ocean,
with the Arabian Sea on its western side and the Bay of Bengal on its eastern side, and …

We present the background, development, and preparation of a state-of-the-art 4D
variational (4DVAR) data assimilation system in the Regional Ocean Modeling System …

As with other Western Boundary Currents globally, the East Australian Current (EAC) is
highly variable making it a challenge to model and predict. For the EAC region, we combine …

A three-dimensional variational data assimilation (3DVAR) scheme has been developed
within the framework of the Regional Ocean Modeling System (ROMS). This ROMS3DVAR …

This 3-day hindcast case study focuses on the effects of the initial errors, a non-negligible
factor in oceanic prediction, on VTS prediction in the NSCS and provides scientific guidance …
