Abstract

The properties of the solar constant variability are considered according to the results of satellite observations (http://lasp.colorado.edu/home/sorce/data/tsi-data/). The obtainment of satellite data with an accuracy of 0.01% that is devoid of atmospheric influence allows a detailed analysis of variations in this index of solar activity and space weather for solar-activity cycles 21–24. The use of wavelet analysis demonstrates the properties of the 11-year cycle in the variation of the solar constant. With the exclusion of variations of the 11-year cycle, it is possible to study short-period processes in each solar cycle. The variations in the solar constant demonstrate their own local spectrum of power periods, which differs from the activity periods according to sunspot observations. The most significant decrease in the solar constant occurs during the passage in the center of the solar disk of large groups of spots and activity complexes that block the solar constant. Thus, the basic properties of the intrinsic variability of the solar constant differ from the properties of the magnetic cycle.

太阳常数的变化作为太阳活动指数的性质

摘要

根据卫星观测结果（http://lasp.colorado.edu/home/sorce/data/tsi-data/）考虑太阳常数变化的特性。在没有大气影响的情况下获得精度为0.01％的卫星数据，可以对太阳活动周期21-24的太阳活动指数和空间天气变化进行详细分析。小波分析的使用证明了11年周期的太阳常数变化特性。排除11年周期的变化，可以研究每个太阳周期中的短周期过程。太阳常数的变化表明了其自身的功率周期局部频谱，根据太阳黑子的观测，其与活动周期不同。太阳常数的最显着下降发生在阻止大量太阳光常数的大量斑点和活动配合物穿过太阳盘中心的过程中。因此，太阳常数的固有变化的基本特性不同于磁循环的特性。
