| 摘 要： | 我们对第12周至第22周的太阳黑子月平均面积数进行统计分析,并与相应的太阳黑子月平均数相比较,结果表明太阳黑子月平均面积数活动周与太阳黑子月平均数活动周有一定的关系。在多数情况下,太阳黑子出现最大值的时间与太阳黑子面积数出现最大值的时间上不一致;太阳黑子平滑月平均数活动周上升期与太阳黑子平滑月平均面积数上升期在大多数情况下不相同;太阳黑子平滑月平均数活动周平均效果的瓦德迈尔效应(Waldmeiereffect)一般要比太阳黑子平滑平均面积数的活动周明显;文中还对太阳黑子平滑月平均面积数活动周的特征进行了分析。

Statistical Characteristics of Solar Cycles Described by the Monthly Averages of Sunspot Areas |
| |
| Abstract: | The monthly averages of sunspot areas in solar cycles 12 to 22 Cycles are employed to analyze their statistical characteristics. The parameter values of solar cycles and then the statistical characteristics of the parameter values of solar cycles are clearly given. Accordingly, the relation of the maximum smoothed monthly averages of sunspot areas and the maximum smoothed monthly averages of sunspot numbers, the relation of the smoothed monthly averages of the sunspot areas with the smoothed monthly averages of sunspot numbers, the relation of the difference of the ascend phase of the smoothed monthly averages of sunspot areas with the smoothed monthly averages of sunspot numbers with solar cycles, the relation of the ascend phase of the smoothed monthly averages of sunspot areas and their maximum values, the relation of the ascend phase of the smoothed monthly averages of sunspot areas and their cycle length, and the relation of the maximum of the smoothed monthly averages of sunspot areas and the asymmetry are presented in this paper.In the mean time,the comparison of the monthly averages of sunspot areas with the monthly averages of sunspot numbers is made. Our results show that the maximum time of sunspot numbers and the maximum time of sunspot areas are not always the same, and the ascent periods of the sunspot-number cycles differ from those of the sunspot-area cycles, and the Waldmeier effect of the monthly averages of sunspot active cycles is more obvious than the monthly averages of the cycles described by sunspot areas. The other statistical characteristics of cycles described by the monthly averages of sunspot areas are also given. |
