SCIENCE Elements of Numerical Ocean Modelling

Numerical ocean models are essentially the mathematical representation of the physical processes that govern the state of the ocean. They are extensively used in the field of oceanography to analyse and predict the behaviour of the ocean. Powerful computers are used to integrate these models to get the values of the ‘state variables’ at desired spatial/temporal intervals. This article takes a close look at the core elements of the numerical ocean modelling that serves as a virtual diving gear to delve into the unfathomable depths of the enigmatic marine world that has captured the imagination of man since time immemorial.
