气象资料分析表明,太阳活动与我国某些地方的降水量之间存在一定规律,由于淮河洪水属于雨洪径流,因这,太阳活动与淮河洪水也可能存在联系。基于这种设想,我们对它们之间的关系作了一些分析。太阳活动是指太阳局部区域经常发生的太阳黑子、光斑、耀斑等现象的总称。由于太阳黑子增多时,上述各种现象发生频率也增大。通常即以太阳黑子的多少作为太阳活动强弱的一个指标,国际上用一个没有单位的量叫黑子相对数来表示。根据苏黎士天文台1749年以来太阳黑子连续记录分析,其变化有明显的周期性,平均
The analysis of meteorological data shows that there is a certain law between the solar activity and precipitation in some parts of China. Because the Huaihe River flood is a part of rainwater run-off, the solar activity may also be linked with the Huaihe River flood. Based on this assumption, we made some analysis of the relationship between them. Solar activity is a general term for the phenomenon of sunspots, flare and flare that often occur in the sun’s local area. As the sunspots increase, the frequency of these phenomena also increases. Usually the sunspots are usually used as an index of the intensity of the sun’s activity. Internationally, the amount of sunspots in the world is called the relative number of sunspots. According to the continuous record analysis of the sunspot in Zurich Observatory since 1749, the change has obvious periodicity, the average
