Ocean Modeling
The ocean plays a leading role in shaping our climate and weather patterns like precipitation, extreme heat, and cold. Even though the ocean plays a role in everything from the air we breathe to daily weather and climate patterns, we know very little about our ocean. Ocean models are numerical models with a focus on the properties of oceans and their circulation.
Challenges in ocean modelling
Uncertainties
-
IC; BC; Terms; Equations
-
Sparse and Gappy Data
-
Intermittent Features
-
Non-stationary, non-Gaussian statistics.
Nonlinear multiscale ocean dynamics
-
Tides, Internal waves, river inflow, fronts, eddies, upwelling, etc.

ROMS
Development and applications of stochastic and deterministic primitive equation ocean modeling systems. Currently working on the Regional Ocean Modeling System (ROMS) for the Northern Indian Ocean.
ROMS is an open source, free-surface, terrain-following, primitive equations ocean model solves the conservation of mass and momentum equations.
