摘要
本文从大气中的热量平衡和陆地下垫面的热传导方程出发,探讨陆-气耦合作用。发现在这耦合系统中存在两类长周期波动:一类是周期约为4—9个月的准半年波;另一类是周期为2—5年的准三年波。重点讨论了准三年波的振荡特性。
In this paper, the land-atmosphere coupling action is explored from the atmospheric heat balanc equation and the heat conduction equation on land underlying surface. It is found there are two long period waves in this coupling system: one is the quasi-half year wave with a period about 4—9 months; the other is the quasi-three years wave with a period about 2—5 years. In this paper, the emphasis is put on the discussion about the characteristics of the quasi-three years oscillation.
