简单气候模式的随机分析解

ON THE STOCHASTIC ANALYSIS FOR A SIMPLE CLIMATE MODEL

中文摘要:

      本文根据热力学第一定律和随机函数建立了一个随机、非线性气候模式,并求出了模式的解析解。结果表明:模式的温度概率密度是一条有双峰值的曲线,太阳辐射的改变将使曲线上峰的数目发生突变;另外,在利用模式分析海温时还发现:各纬度海温对天气过程的扰动作用将呈现不同的响应。

英文摘要:

      using first thermodynamic law and stochastic function, a stochastic nonlinear climate model is proposed. Meanwhile, the model analytical solution is solved. The result indicates that global temperature probability density function have two peaks. If solar radiation variates, a sudden change of peak number will be happened.In addition, we find that there are different sea temperature responses because of different latitude.
