海气耦合随机模式的CO_2温室效应的研究

THE RESEARCH OF CO_2 EFFECT WITH AIR-SEA COUPLING STOCHASTIC MODEL

从海－气相互作用的角度出发，研究了ＣＯ_２温室效应对海温距平的影响；建立了非线性海－气耦合随机模式及绝热条件下的朗之万动力学方程和福克－普朗克方程，并给出了方程组的解析解为高斯分布，在稳态情况下为布朗运动，得到了在ＣＯ_２加倍时海温距平平均值增温为１．８１℃，与当前研究ＣＯ_２对大气温度影响的结果一致。

This paper researches sea temperature affected by CO_2 effect with air-sea interaction andbuilds-up nonlinear air-sea coupling stochastic model which turns into Langevin Equation andFokker-Planck Equation with fastest method. Solution of model is Gaussion distribution; state solutionof model is Brownian motion. The average value of sca-temperature declinalion adds 1.81℃ with doub-ling CO_2.
