能量平衡气候模式的敏感性试验

SENSITIVITY EXPERIMENTS AS SIMULATED WITH AN ENERGY BALANCE MODEL

本文利用简单的一维能量平衡模式模拟全球冰雪面积增减,太阳常数增减,地面反照率增减,大气中二氧化碳浓度增减以及气溶胶浓度增减等对全球温度的影响。同时还模拟多个因子综合对冰河期的影响。敏感试验给出各种自然变化和人类活动对全球温度影响的可能的数值结果,从而为保护大气与环境提供一定参考数据。

Changes of the global temperature induced by the changes ice and snow areas,solar con-stant,surface albedo,carbon dioxide,and aerosol have been simulated with a one—dimensionalenergy balance model.The effects of several factors on the ice age temperature have been ana-lysed.Possible numerical results of the global temperature change induced by the natural varia-tions and human activities are shown.Therefore,some reference values are given to protection ofthe atmosphere and environments.
