Relation between Meteorology and Lightning Charge Transfer Observed at Nikaho Wind Farm in Winter

In recent years, with the increase of wind turbines on the coast of the Sea of Japan, damages caused by winter lightning are often reported. The authors have carried out measurement of the current waveform on winter in 2013 to 2015 at Nikaho wind farms. In this paper, we discuss the relation between the meteorology and the charge transfer observed at Nikaho wind farm in winter.
