| 摘 要： | 本文将非线性热力学理论应用到大尺度海洋系统,找到了一个适合于描述海温扰动发展的热力学判据。计算表明:这种热力学判据能够较好地报出海温异常事件,估计海温异常的强弱。本文还利用这种热力学判据分析了海洋与大气之间的热交换和平流效应对海温扰动演化的影响。

| Abstract: | Nonlinear thermodynamical theory is used to investigate large scale ocean systems. A Lyapunov function which is suitable for describing the stability of sea surface temperature disturbance is found and a thermodynamical criterion of development of sea surface temperature disturbance is proposed. The calculations demonstrate that the therxnodynamical criterion predicts sea temperature anomalies and estimates their intensities quite well. The thermodynamic criterion is also used to analyse the effects of heat exchange between the ocean and the atmosphere and ocean current transference on the development of sea temperature disturbance. |
