Title:
MS3
Hamiltonian dynamics of climate and forecast models
Type:
Atmosphere / climate / weather models
Room:

Conservation of energy plays a fundamental role in the dynamics of geophysical models for the Earth's ocean and atmosphere.  For many climate and forecast models the energy conservation law is embodied in the symmetries of the Poisson bracket of the Hamiltonian functional and these models can be systematically derived in terms of varitional principles.  This mini-symposium brings together researchers focused on developing computational methods for preserving Hamiltonian dynamics in climate and forecast models.
