Abstract：Based on data from X-band vertically pointing weather radar and ground rainfall stations,this article takes a convective precipitation process and a stratiform precipitation process in Ding'an,Hainan in the summer of 2020 as the research objects.Through the vertically pointing observation mode,it explores the echo characteristics of different types of precipitation clouds at different heights and their relationship with ground precipitation,and analyzes the differences in these characteristics in precipitation intensity inversion.The results show that the inversion accuracy of the Z-R relationship is significantly affected by raindrop spectra,with stratiform precipitation being overestimated and convective clouds underestimated.Furthermore,the correlation between reflectivity and ground precipitation gradually weakens with increasing height,requiring adjustments to parameters based on cloud type.In stratiform precipitation,the inverted rainfall intensity is generally higher,and its correlation with ground precipitation gradually decreases with increasing height.In convective precipitation,there is a significant temporal difference between the inverted rainfall intensity and the actual ground rainfall intensity.The research results can provide a reference for the future application of weather radar in precipitation observation.
