Sentences with phrase «complex numerical models»

Descriptive physical oceanography seeks to research the ocean through observations and complex numerical models, which describe the fluid motions as precisely as possible.

It's no secret that models — not just of climate, but * all * complex numerical models!

Climate models are complex numerical models based on physics that amount to hundreds of thousands, if not millions, of lines of computer code to model Earth's past, present and future.

Not exact matches

He uses a combination of analytic and simple numerical models to build physical intuition for complex phenomena.

For so many inputs and complex interractions, such large numerical models (which means A LOT of numerical approximations — even on supercomputers), clearly the fact that they more or less fit the 20th century temperature is not enought.

Experience with solution algorithms, data assimilation methods and tools, coupling of components and processes, nonlinear and linear solvers, limiters, and / or other numerical issues common with complex codes within earth system models of varying complexity

I'd be curious to know what quantative information you use to track what seems to me to be scores of sources of model and numerical errors in such a complex computer code as you are describing here.

JIGSAW (GEO) is a set of algorithms designed to generate complex, variable resolution unstructured meshes for geophysical modelling applications, including: global ocean and atmospheric simulation, numerical weather prediction, coastal ocean modelling and ice - sheet dynamics.

Among other reasons, small errors in the numerical modelling of complex processes have a nasty habit of accumulating with time.

It is, imho, not justified once the numerical model becomes complex enough, because the most part of the model is not from fundamental laws, but from numerical approximations, parametrisation, and a lot of interraction between different modules and physics.

I explore ideas using hierarchies of idealized atmosphere - ocean models, ranging from simple mathematical descriptions to complex coupled numerical calculations.
