Analysis of Lightning Activities of Lishui Bridge Based on Statistical Method


Article Preview

Using lightning location data of 9 stations in Hunan Province from 2007 and 2009, we analyze the lightning strength and frequency in Lishui bridge area and have a description of yearly and daily distribution. It shows that Lishui bridge regional lightning presented a mono-peak feature. Lightning mainly occurs from February to September, especially in August. Daily distribution here is extremely uneven. And lightning most happens in 6 a.m. and 4 p.m., which is different from most parts of China. Ground flash density near the bridge is 2.2 times /km2•a. Lightning intensity ranges from 25 kA to 65 kA. Strong lighting at 40-50 kA, even up to 200 kA, is more likely to take place. It has very important significance in choosing the lightning flow of surge protective devices.
