From the observational results we find that stratiform precipitation is predominant than convective precipitation in cyclone induced precipitation clouds. Where as in the case of NE monsoon thunderstorm precipitation convective cloud fraction is more than stratiform clouds. The cyclone induced precipitation is associated with higher concentration of small drops (small and middrops) in stratiform region (convective region) than NE monsoon precipitation. The average mass weighted diameter, Dm of cyclone induced precipitation is less than the NE monsoon precipitation both in stratiform and convective cloud regions. The observed RSD are found distinctly vary from cyclonic and NE monsoon thunderstorm precipitating clouds. 出版者： India Meteorological Department 出版日期： 2013-01-01 出處： MAUSAM, 2013-01, Vol.64 (1), p.35-48 識別號： ISSN: 0252-9416 識別號： DOI: 10.54302/mausam.v64i1.653
