Abstract:
Based on the radarbased lightning warning products of Zhejiang meteorological Observatory running for many years (60 min early warning, spatial resolution 1 km×1 km, four warning levels), considering the high false negative rate of Lightning Warning Products, a method of lightning warning is presented by blending lightning location data and atmospheric electric field data. The results from the new lightning warning method in 2018 are verified, with a POD (Percent of Doom) of 31.52%, FAR (False Alarm Rate) of 29.86%，and CSI (Critical Success Index) of 61.24%, which are better than those from the previous method based on singlefactor observation. It can be obviously seen that this method has more significant indication and reference for Zhejiang lightning forecasting and warning.
