Statistical relationship between aerological data and daily precipitation at Buenos Aires

The basic statistics of aerological variables obtained from radiosonde data at Ezeiza, Buenos Aires, Argentina, for 1986 are examined, and their relationships with occurrence and non-occurrence of daily local precipitation are analysed. The resulting samples are statistically different for nearly al...
