一、前言 在长期天气过程和气候形成的理论中,海洋起着重要的作用。但是海洋是一种缓慢流动的介质,比热也远比大气的比热大,从大范围运动角度来看,大气运动特别大尺度天气过程,相对说来比较活跃和变化速度较快,这种较快的天气起伏,将影响海水的潜热和感热输送,使海温发生变化,然而海温的气候变化是一个缓慢过程,而且是一个大范围现象,因此可以将天气过程的起伏看成一种随机强迫,从这一观点出发,Frankignoul.andHasselman采用简单的随机模型,探讨了海温异常的成因与变化,得到了引人注目 I. Preface The oceans play an important role in the theory of long-term weather processes and climate formation. However, the ocean is a slowly flowing medium, and the specific heat is far greater than the specific heat of the atmosphere. From a large-scale movement point of view, the atmospheric movement, especially the large-scale weather process, is relatively active and changing at a relatively fast speed. Faster weather fluctuations will affect the seawater latent heat and sensible heat transfer, the sea temperature changes, but the temperature of the sea temperature is a slow process of change, but also a wide range of phenomena, so the weather process fluctuations can be seen as a Randomly forced, from this point of view, Frankignoul.Hasselman using a simple random model, discussed the causes and changes of SST anomalies, get the attention
