Towards a Fluctuation Theorem in an Atmospheric Circulation Model
arXiv:1211.1181 · doi:10.1103/PhysRevE.87.052113
Abstract
An investigation of the distribution of finite time trajectory divergence is performed on an Atmospheric Global Circulation Model. The distribution of the largest local Lyapunov exponent shows a significant probability for negative values over time spans up to 10 days. This effect is present for resolutions up to wave numbers l=42 (~ 250km). The probability for a negative local largest Lyapunov exponent decreases over time, similarly to the predictions of the Fluctuation Theorem for entropy production. The model used is hydrostatic with variable numbers of vertical levels and different horizontal resolutions.
