【摘要】 太阳每年给地球大气的热量基本上是一个定量,这个定量不因大气变化而改变,即大气的热量是守恒的。由此引出大气状态的平衡问题:地球上任何一个区域的大气吸收的热量若出现明显偏多或偏少,必有另外区域大气吸收的热量出现偏少或偏多。它是分析厄尔尼诺和拉尼娜现象成因机制和它们对全球气候变化影响的科学依据。基于此,根据我国浙北地区的气象资料和全球年气温变化,以1997-1998年强厄尔尼诺为例,分析了它们的成因和对气候变化的影响。更多还原

【Abstract】 The heat in atmosphere received from sun annually is basically a constant,which does not change when climate changes,i.e.,the heat in atmosphere is conserved.A balance problem in atmosphere arises: any apparent increase or decrease in the heat absorption of atmosphere in any region of earth will be compensated by corresponding decrease or increase in another region.The fact is a scientific foundation to analyze the formation mechanism of El Nino and La Nino phenomenon and their influence on global climate change.Based on meteorological data in the north of Zhejiang and the annual global temperature change,the typical El Nino phenomenon between 1997-1998 are taken as examples to investigate their formation mechanism and its influence on climate change.更多还原
