dycore

Abbreviation of dynamical core.

• IPA^(key): /ˈdaɪ.kɔɹ/

dycore (plural dycores)

1. (meteorology, climatology, computing) A computational module within a numerical weather prediction or climate model that solves the fundamental equations governing atmospheric or oceanic dynamics, such as the Navier–Stokes equations, to simulate fluid motion on Earth.

     Based on the results of Fox-Rabinovitz (2000) and Fox-Rabinovitz et al. (1997, 2000, 2001), whose stretched-grid GCM has successfully produced variable-resolution global predictions, we have made predictions with the SEAM dycore and simple HS physics applying global and regional scaling concurrently, to check SEAM's skill using LMR under conditions similar to Fox-Rabinovitz et al. (2001, hereafter F-R).

     The notion of multi-scale applies to dycore computations both spatially and temporally.

     So, it is important to be aware that the dynamical core (dycore, for short) is not the only piece of a GCM responsible for the challenging numerical task of advecting fluid.
