摘要
本文首先用超熵产生作为判据,讨论了北半球气温的突变情况。其结果,与记录相符.而后,在气候层次理论和非线性动力理论的基础上,我们提出了气候突变的三种机制;跃迁突变、“贯穿”突变和转换突变。
First, the catastrophe of modern air temperature of Northern Hemisphere is discussed by using excessentrophy production as a criterion, and the result is good qualitative agree with the record. Then, three mechanisms of climatic catastrophe: jump catastrophe, penetrating catastrophe and transform catastrophe are raised on the basis of the climatic hierarchial theory and nonlinear dynamic theory.
