本文介绍并研究了一个从平流层波带流相互作用霍尔顿和质量模型中截取的简单动力学模型。该模式由三个常微分方程组组成，并由两个参数控制：行星波的初始振幅和纬向风的垂直梯度。与季节变化和太阳变率的变化被引入作为纬向风梯度的周期性调制。气候对这些变化的主要反应是通过调节寒冷和温暖的冬天的数量。
A simple dynamic model, truncated from the stratospheric wave‐zonal flow interaction Holton and Mass model, is introduced and studied. This model consists of three ordinary differential equations controlled by two parameters: the initial amplitude of planetary waves and the vertical gradient of the zonal wind. The changes associated with seasonal variations and with the solar variability are introduced as periodic modulations of the zonal wind gradient. The major climatic response to these changes is seen through modulation of the number of cold and warm winters.
