要約(英語): Wind turbines at the coast of Sea of Japan are often exposed to energetic upward lightning flashes in winter, and it is essential to obtain the dataset of parameters for such lightnings for effective operations or inspections. Currently, the height of wind turbines are becoming taller for higher power generation, and this may change lightning performances such as the escalation of frequency of the lightning strikes. However, there are few studies of current observations for upward lightning flashes hitting wind turbines which height are over 100 m. In addition, the variation of the characteristics of upward lightning flashes currents depends on observation areas and the effect of the global warming remains unclear. Thus, the observation of upward lighting current has started at the Kashiwazaki-Kariwa power plant since 2020. This paper reports the summary of the observation system and observed data as of March 2022.
