Abstract

Data from a long-term experiment with monitoring of the vertical component of the electric field at the base from the surface to the bottom showed oscillations with quasi-periods of tens to hundreds of days in Lake Baikal. They are not caused by any internal sources, but they show a close relationship with intermittent oscillations of the solar X-ray radiation flux. This relationship is characterized by a high (up to 0.9) correlation with a large (multiday) delay. Variations in the electric field are naturally interpreted as a manifestation of the variability of the current in the hydrospheric segment of the global electric circuit over the Baikal Rift. The large delay can be explained by the indirect mechanism of influence in the fluxes of X-ray radiation from the Sun on the convection component of the current in the atmosphere through its complex effect on meteorological processes. In this case, the degree of correlation of X-ray radiation with the electric field is always very high, while the delay in different years can vary by an order of magnitude.

贝加尔湖电场垂直分量中太阳X射线辐射变化的表现

摘要

来自一项长期实验的数据，该实验监测了从表面到底部的底部垂直电场的分量，在贝加尔湖中出现了几十至数百天的准周期振荡。它们不是由任何内部来源引起的，而是与太阳X射线辐射通量的间歇振荡密切相关。这种关系的特点是相关性高（最多0.9），延迟大（多天）。电场的变化自然被解释为贝加尔湖裂谷上全球电路水圈部分电流变化的一种表现。较大的延迟可以通过间接影响机理来解释，该机理是来自太阳的X射线辐射通量对气象过程的复杂影响，从而对大气中电流的对流分量产生影响。在这种情况下，X射线辐射与电场的相关度始终很高，而不同年份中的延迟可能相差一个数量级。
