179 | +## Ocean Dynamics | |

180 | +- Global model: look like Perpetual Ocean, generally for climate simulations | |

181 | +- Regional model: see GoSL Observatory, generally for immediate use | |

182 | + | |

183 | +Based on the Navier-Stokes Equations for incompressible fluid in a rotating frame of reference | |

184 | +- 3 momentum equations (one for each component) | |

185 | +- 1 continuity equation | |

186 | +- Boussinesq approximation (ρ = ρ_0 + ρ', ρ ~ ρ_0 except for gravity) | |

187 | + | |

188 | +DNS: Direct Numerical Simulation | |

189 | +- Solve equations down to the smallest eddies | |

190 | +- Typically with periodic boundary conditions | |

191 | + | |

192 | +RANS: Reynolds Averaged NS equations | |

193 | +1. Decompose u = u\_avg + u', u'\_avg = 0 | |

194 | +2. Plug in NS, get NS\_avg + (u' · ∇ u')\_avg | |
