This paper analysed variety ef raindrop spectra and their characteristic parameters along a horizontal level. Within horizontal scale ranging 60km (elevation 1.-1.8km) Existed apparently three peaks of raindrop concentration and precipitation intensity.Raindrop spectra and their characteristic parameters were different at peaks and troughs of precipitation intensity. Raindrop spectra may be fitted with exponential form n(D) = NO exp (-XD). Samples of correlation signification level a<0.01 hold 71. 8% of total samples.
