要約(英語): The authors analyzed the relation between height of －10℃ air layer derived from Meso-Scale Model and 51 examples of damage at low structures by winter lightning at the coastal areas of the Sea of Japan in Tohoku in three winter seasons. We also discussed the number of lightning discharges detected by the Japanese Lightning Detection Network (JLDN) and height of －10℃ air layer when those damage occurred. In the results，the characteristics of lightning discharges were often similar to single lightning flash when height of －10℃ air layer was less than 2000 m. Most damage at low structures by winter lightning occurred when height of －10℃ air layer was higher than 2000 m. The number of lightning discharges tended to become large when a cold front passed over the coastal area of the Sea of Japan in Tohoku. The damage caused by winter lightning concentrated between the middle of November and early January and did not occur when height of －10℃ air layer was less than 1200 m.
