Abstract：Based on the data of atmospheric electric field,the weather processes of rainfall,snowfall and thunderstorm occurred in Lishui from 2017 to 2018 were compared by using the difference and wavelet analysis methods.It is found that the difference amplitude of thunderstorm is the largest in all processes.The difference value of thunderstorm occurrence period is one order of magnitude larger than that of rainy weather process,and more than one time larger than that of snowfall .After wavelet transform analysis,rainfall and snowfall are increased by one order of magnitude.After the transformation of rainfall and snow,the amplitude is lower than that of the original model,the fluctuation of wavelet signal becomes smooth,and the rapid jump of positive and negative poles no longer occurs.The small wave shape fluctuates smoothly without sudden jump.The wavelet transform signal shows active up and down wave fluctuation during the thunderstorm period,and the amplitude is significantly larger than that of rainfall and snowfall.
