【摘要】 <正> 根据不同地区的许多观测表明,雨滴平均谱的极限状态趋于指数形式。1984年8月10日至10日受8407号台风减弱为低压的影响,长春降了大暴雨,降水量为112.3mm,从10日06时30分开始,用滤纸色斑法,每隔5分钟观测一次雨滴谱,到11日04时,共取雨滴谱259份。本文根据这次层状云大暴雨雨滴谱资料,研究了指数形式雨滴谱N_D=N₀e^-λD的参数N₀和λ的确定,并对不同方法拟合的经验更多还原

【Abstract】 Based on the data of raindrop spectra of stratiformis rain storm in Changchun on 10-11, Aug. 1984, the parameters N0 and λ for raindrop size distribution of the form ND = Ng e-λD were researched. The errors of different ways-which got No and λ were calculated. The results show that No and λ as a function of I are the best way to establish raindrop size distribution.更多还原
