地球大气温度起伏的一个简单模式的持久性

Persistence in a Simple Model for the Earth's Atmosphere Temperature Fluctuations

Arturo Berrones

摘要:

本文研究了在一个简单的地球大气温度波动随机模型中,由于存在一些不同的时间尺度而引起的效应。该模型由一组耦合的随机演化方程组成的耗散动力学描述。该系统显示出与最近观察相似的特征。与自回归模型等其他方法相比,大气温度的波动取决于具有明确物理意义的参数。一个简化版本的模型构造和时间自协方差函数明确地写。

英文摘要:

The effect caused by the presence of a number of distinct time scales in a simple stochastic model for the Earth's atmosphere temperature fluctuations is studied. The model is described by a dissipative dynamics consisting of a set of coupled stochastic evolution equations. The system shows features that resemble recent observations. In contrast to other approaches, like autoregressive models, the fluctuations of the atmosphere's temperature depend on parameters with clear physical meaning. A reduced version of the model is constructed and its temporal autocovariance function is explicitly written.
