利用1979-2010年间的JRA-25再分析资料、太阳常数观测资料,重现了1979-2010年间的各能量的时间序列,并对整层大气、对流层大气和平流层大气这三个大气层的能量的演变规律及其与太阳活动的关系进行了分析。结果表明:(1)整层大气的总能量和对流层大气的总能量,两者都存在一个显著的3.7年的周期;而平流层大气的总能量具有一个显著的11-22年的振荡周期;平流层大气对太阳活动的响应,与对流层大气对太阳活动的响应有所不同:平流层大气的总能量的变化略落后于太阳常数的变化,但是整层大气和对流层大气的总能量的变化均是超前于太阳常数的变化。(2)整层大气、对流层大气和平流层大气这三个层次的总能量和太阳常数分别具有显著的4-11年的共振周期、5.5-7.3年的共振周期和3.7-11年的共振周期。 |

Abstract: |
Using JRA-25 reanalysis data form 1979~2010,integrate the expression of all kinds of energy .Taking the shape of the earth into consideration, we add the weight to the zonal integral before further study. Then, we repeat the time series of all kinds of energy form 1979 ~2010. Using observational data of solar constant from 1979 to 2010, the evolution of the energy of the total atmosphere, the energy of theStroposphere atmosphere and the energy of the stratosphere energy and the relationship between the energy and solar constant have been analyzed with the spectrumSand the wavelet technique. The results of continuous spectrum indicate that the energy of the total atmosphere has a significant period of 3.7 a , and the troposphere atmosphere also has the same oscillation in the same frequency band. However, the energy of the total atmosphere has a significant period form11 to 22 a . The results of Cross spectrum indicate that the solar constant and the energy of the total atmosphere present a significant oscillation period from 4 to 11 a, the solar constant and the energy of the troposphere atmosphere present a significant oscillation period from 5.5 to 7.3 a and the solar constant and the energy of the stratosphere energy present a significant oscillation period from 3.7 to 11 a. |
