太阳活动、大气臭氧和平流层温度相关分析研究

STUDY OF THE CORRELATION BETWEEN SOLAR ACTIVITY, OZONE AND TEMPERATURE IN THE STRATOSPHERE

本文分析了10.7 cm太阳射电通量、太阳耀斑爆发和低层平流层温度、大气柱体臭氧总量之间的相关联系。指出无论是年时间尺度或11时间尺度二者都存在一定的相关性。这种相关性主要发生在高纬地区,且以QBO为W型位相及冬季月份最明显。分析又指出,低层平流层温度、大气臭氧总量与太阳活动之间的响应关系在两种时间尺度上基本都同步。文中还简单地讨论了形成上述相关联系的可能物理机制,指出太阳紫外辐射和高能粒子流是影响地球大气的太阳活动主载体,通过对大气臭氧含量的调制来影响平流层温度。

The correlations between the 10.7 cm solar radio flux, the solar flare burst and the temperature in the lower stratosphere, the column ozone in the atmosphere has been analysed, respectively, in this paper. The results show that there are certain correlations between them on two time scales: 11 years and a few days. The correlations usually occur in the higher latitude, and are very obvious for the west phase of the quasi-biennial-oscillation (QBO) and in the winter. The correlations between the solar activity and the temperature in the lower stratosphere, or the column ozone are synchronization for two time scales. The possible physical mechanism above mentioned correlations are also discussed in the paper. The results indicate that the solar ultraviolet radiation and high-energy corpuscular stream are main carriers of solar variability to influence on the lower atmosphere. It is a possible mechanism that the variation of temperature in the stratosphere is modulated by the variation of the column ozone.
