Effect of solar activity and geophysical disturbance on physical-chemical processes in liquid medium: Preliminary analysis of storm-glass activity

Changes in the state of a solution in storm glasses (Fitzroy retort) have been recorded by measuring the height of the level of crystals. Devices manufactured by a group of Crimean researchers have been used to measure these characteristics daily since 1995. Fragments of an accumulated observation dataset have been processed employing standard meteorological and cosmophysical indices. It is found that, 2–3 days before isolated sharp drops in the atmospheric pressure, crystal formation intensifies synchronously in two devices. A relationship is found between the activity under study and changes in the A _p geomagnetic-disturbance index and the flare-intensity index. There is a set of quasi-stable periods in variations of the activity of storm glasses, of which the 120-, 185-, and 360-day periods are most significant. The obtained results are generally consistent with views that changes in the background electromagnetic low-frequency fields are a physical agent influencing the process of crystal formation.
