海气耦合随机动力模式的Fokker-Planck方程

SOLUTION OF COUPLED AIR SEA STOCHASTIC DYNAMIC MODEL WITH MATRIX CONTINUOUS-FRACTION METHOD

将描写海温和气温交互作用的随机动力模式化为一个Ｆｏｋｋｅｒ－Ｐｌａｎｃｋ方程（ＦＰＥ），然后用矩阵连分法进行求解，并对二氧化碳增温效应进行了计算。当ＣＯ２从３３０ｐｐｍ增加到６６０ｐｐｍ时增温１．２℃，模式中存在的优势周期为３～４年，当ＣＯ２倍增时各周期有延长的趋势。

The stochastic dynamic model describing the air sea interaction is transformed into a Fokker Planck equation that is then solved by the matrix continuous fraction method. As an example of the solution, the warming by CO 2 increase is calculated and its increment is 1.2 ℃ while CO 2 concentration in the atmosphere increases from 330 to 660 ppm. In the model the dominant period is 3～4 years and it is revealed that the periods tend to get longer when CO 2 doubling occurs.
