Abstract：Based on the observation data of the ground atmospheric electric field in Licang weather station from March to August in 2016,the atmospheric electric field characteristics of the ground are analyzed by the absolute mean of the daily atmospheric electric field and the differential ground electric field.Whether it is peak or pulse,it is easy to see the thunderstorm process after timing difference curves of electric field.And the polarity distribution is obvious.Combined with multi-level threshold warning,the use of timing differential electric field for early warning can reduce the rate of return.
