摘要/Abstract

摘要： 基于能量平衡气候模式,考虑了随机力对海气相互作用的影响和不同时空尺度耦合的作用,将描写海温和气温交互作遥随机动力模式化为一个FokkerPlanck方程,然后用矩阵连分法进行求解,并对CO₂增温效应进行了计算,当CO₂从330×10^-6增加到660×10^-6时增温12K,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.

关键词: 海气相互作用, 随机气候模式, 福克普朗克方程, 矩阵连分法

Abstract: The effects of stochastic forcing on air-sea interaction, energy baiance ciimate modei is considered.The noniinear source is dynamicai heat transport.The roie to coupiing different temporai and spatiai scaies of the atmosphere is examined.A stochastic dynamicai modei of air-sea interaction is derived via the Fokker-Pianck eguation (FPE).The FPE from statisticai mechanics is used to obtain a time evoiution of the probabiiity density function and the ciimatic potentiai function.The matrix-continued fraction method (MCFM) is appiied to get the soiution with which effect of greenhouse gases was caicuiated.As a resuit, sea surface temperature rises by 1.2 K,meanwhiie the basic period is about 3~4 years and becomes ionger on doubiing CO₂.

Key words: air-sea interaction, stochastic ciimate modei, Fokker-Pianck eguation, matrix-continued fraction method
