| description | Thunderstorm and cloud activities sometimes show a 27-day period, and this has long been studied to uncover a possible important link
to solar rotation. Because the 27-day variations in the solar forcing parameters such as solar ultraviolet and galactic cosmic rays
become more prominent when the solar activity is high, it is expected that the signal of the 27-day period in meteorological
phenomena may wax and wane according to the changes in the solar activity level. In this study, we examine in detail the intensity
variations in the signal of the 27-day solar rotational period in thunder and lightning activity from the 18th to the 19th centuries
based on 150-year-long records found in old diaries kept in Japan and discuss their relation with the solar activity levels. Such
long records enable us to examine the signals of solar rotation at both high and low solar activity levels. We found that the signal
of the solar rotational period in the thunder and lightning activity increases as the solar activity increases. In this study, we
also discuss the possibility of the impact of the long-term climatological conditions on the signals of the 27-day period in
thunder/lightning activities. |
